Parallel Expanded Event Simulation of Tightly Coupled Systems

12:1--12:26
The technical evolution of wireless communication technology and the need for accurately modeling these increasingly complex systems causes a steady growth in the complexity of simulation models. At the same time, multi-core systems have become the de facto standard hardware platform. Unfortunately, wireless systems pose a particular challenge for parallel execution due to a tight coupling of network entities in space and time. Moreover, model developers are often domain experts with no in-depth understanding of parallel and distributed simulation. In combination, both aspects severely limit the performance and the efficiency of existing parallelization techniques.
We address these challenges by presenting parallel expanded event simulation, a novel modeling paradigm that extends discrete events with durations which span a period in simulated time. The resulting expanded events form the basis for a conservative synchronization scheme that considers overlapping expanded events eligible for parallel processing. We furthermore put these concepts into practice by implementing Horizon, a parallel expanded event simulation framework specifically tailored to the characteristics of multi-core systems. Our evaluation shows that Horizon achieves considerable speedups in synthetic as well as real-world simulation models and considerably outperforms the current state-of-the-art in distributed simulation.

Data Dependency based Parallel Simulation of Wireless Networks

291-300
Simulation of wireless systems is highly complex and can only be efficient if the simulation is executed in parallel. To this end, independent events have to be identified to enable their simultaneous execution. Hence, the number of events identified as independent needs to be maximized in order to increase the level of parallelism. Traditionally, dependencies are determined only by time and location of events: If two events take place on the same simulation entity, they must be simulated in timestamp order. Our approach to overcome this limitation is to also investigate data-dependencies between events. This enables event reordering and parallelization even for events at the same simulation entity. To this end, we design the simulation language PSimLa, which aids this process. In this paper, we discuss the PSimLa design and compiler as well as our data-dependency analysis approach in detail and present case studies of wireless network models, speeded up by a factor of 10 on 12 cores where time-based parallelization only achieves a 1.6x speedup.

EchoRing: A Low-Latency, Reliable Token-Passing MAC Protocol for Wireless Industrial Networks
2015
5
20
Spurred by recent industrial trends, such as factory automation or phase synchronization in the smart grid, there is a significant interest for wireless industrial networks lately. In contrast to traditional applications, the focus is on carrying out communication at very short latencies together with high reliabilities. Meeting such extreme requirements with wireless networks is challenging. A potential candidate for such a network is a token-passing protocol, as it allows to bound latencies. However, it lacks mechanisms to cope with the dynamics of wireless channels. In this paper, we present EchoRing, a novel wireless token-passing protocol. Cooperative communication and an improved fault tolerance allow this decentralized protocol to support industrial applications over wireless networks. Based on experimental results, we demonstrate the suitability of EchoRing to support demands of industrial applications. EchoRing outperforms other schemes by several orders of magnitude in terms of reliability for latencies of and below 10ms.

Semi-Static Interference Coordination in OFDMA/LTE Networks: Evaluation of Practical Aspects
2014
9
21
To minimize interference in LTE networks, several inter-cell
interference coordination (ICIC) techniques have been in-
troduced. Among them, semi-static ICIC offers a balanced
trade-off between applicability and system performance. The
power allocation per resource block and cell is adapted in
the range of seconds according to the load in the system.
An open issue in the literature is the question how fast the
adaptation should be performed. This leads basically to a
trade-off between system performance and feasible compu-
tation times of the associated power allocation problems. In
this work, we close this open issue by studying the impact
that different durations of update times of semi-static ICIC
have on the system performance. We conduct our study
on realistic scenarios considering also the mobility of mobile terminals. Secondly, we also consider the implementation aspects of a semi-static ICIC. We introduce a very efficient implementation on general purpose graphic processing units, harnessing the parallel computing capability of such devices. We show that the update periods have a significant impact on the performance of cell edge terminals. Additionally, we present a graphic processing unit (GPU) based implementation which speeds up existing implementations up to a factor of 92x.

Analytical Model of Proportional Fair Scheduling in Interference-limited OFDMA/LTE Networks
2013
9
Various system tasks like interference coordination, handover decisions, admission control etc. in upcoming cellular networks require precise mid-term (spanning over a few seconds) performance models. Due to channel-dependent scheduling at the base station, these performance models are not simple to obtain. Furthermore, upcoming cellular systems will be interference-limited, hence, the way interference is modeled is crucial for the accuracy. In this paper we present an analytical model for the SINR distribution of the scheduled subcarriers of an OFDMA system with proportional fair scheduling. The model takes the precise SINR distribution into account. We furthermore refine our model with respect to uniform modulation and coding, as applied in LTE networks. The derived models are validated by means of simulations. In additon, we show that our models are approximate estimators for the performance of rate-based proportional fair scheduling, while they outperform some simpler prediction models from related work significantly.

Rate selection analysis under semi-persistent scheduling in LTE networks
2013

1184,1190
Upcoming LTE networks have basically two different modes for scheduling data in the down-link by the base station. Dynamic scheduling brings the advantage of exploiting instantaneous channel state information while it puts on the other hand a significant burden on the system in terms of overhead and computation requirements. Especially for small packets that show up periodically, the overhead is typically too high. Therefore, the base station can serve such packet flows by the semi-persistent scheduling mode. In this mode, a certain resource allocation is fixed to a periodic schedule. While this does not allow any longer to exploit instantaneous channel states, it requires much less overhead. In this paper, we address the problem of selecting a modulation and coding scheme for such semi-persistent scheduling grants. The problem lies here in the stochastic characterization of the resource blocks over the next few seconds while on the other hand estimating based on such a characterization the blok error rate (and hence the average goodput). We provide a novel scheme, which outperforms all previously presented schemes significantly. The underlying model that we provide can also be used for any other long-term decision in an LTE system with semi-persistent scheduling such as interference coordination, handover decision etc.

On Semi-Static Interference Coordination under Proportional Fair Scheduling in LTE Systems
2013
8
In this paper we consider the design of semi-static inter-cell interference coordination schemes for LTE networks. In this approach, base stations coordinate the power settings per resource block over long time spans such as seconds. In order to optimize the power settings, one needs to employ models which predict the rate of terminals over the next coordination period under the usage of a given power setting. However, these models are typically quite simple and neglect the impact from fading as well as from dynamic resource allocation performed at the base stations on a millisecond basis. Ignoring such properties of OFDMA networks leads therefore to suboptimal transmit power settings. In this paper, we study the impact from a precise rate prediction model that accurately accounts for fading and dynamic resource allocation. On the down-side, this more precise model leads to a much more involved optimization problem to be solved once per coordination period. We propose two different heuristic methods to deal with this problem. Especially the usage of genetic algorithm results to be promising to counteract the complexity increase. We then study the overall system performance and find precise rate prediction models to be essential for semi-static interference coordination as they provide significant performance improvements in comparison to approaches with simpler models.

A Receiver-Based 802.11 Rate Adaptation Scheme with On-Demand Feedback
2012

1--7
Classical 802.11 rate adaptation algorithms rely on feedback from the receiver to correctly choose a sending rate, typically in the form of acknowledgments (ACKs). In the absence of such frames, novel techniques are required for rate selection.
We present OFRA, a receiver-based rate adaptation algorithm that works with ACK-less traffic. Feedback information is sent on-demand using a control frame to explicitly inform the transmitter about which bit rate to use on subsequent data frames. This approach guarantees standard conformity and exhibits fast and accurate bit rate adaptation at the cost of a modest overhead increase. We evaluate the performance of OFRA against various state-of-the-art rate adaptation schemes by means of simulations. If ACK frames are to be transmitted, OFRA performs better than related work in most considered scenarios, and on par in the others. In the absence of ACKs, OFRA provides large goodput gains under good channel conditions and comparable goodput in other situations.

Runtime Efficient Event Scheduling in Multi-threaded Network Simulation

Developing an efficient parallel simulation framework for multiprocessor systems is hard. A primary concern is the considerable amount of parallelization overhead imposed on the event handling routines of the simulation framework. Besides more complex event scheduling algorithms, the main sources of overhead are thread synchronization and locking of shared data structures. As a result, the overhead of parallelization may easily outweigh the benefits of parallelization in comparison to classic sequential simulation.
We introduce two efficient event handling schemes based on our parallel-simulation extension Horizon for the OMNeT++ simulator.First, we present a \emph{push-based event handling scheme} to minimize the overhead of thread synchronization and locking. Second, we complement this scheme with a novel \emph{event scheduling algorithm} that significantly reduces the overhead of parallel event scheduling. Lastly, we prove the correctness of our scheduling algorithm. Our evaluation reveals a total reduction in the event handling overhead of up to 16x when combining both schemes.

Expanding the Event Horizon in Parallelized Network Simulations

The simulation models of wireless networks rapidly increase in complexity to accurately model wireless channel characteristics and the properties of advanced transmission technologies. Such detailed models typically lead to a high computational load per simulation event that accumulates to extensive simulation runtimes. Reducing runtimes through parallelization is challenging since it depends on detecting causally independent events that can execute concurrently. Most existing approaches base this detection on lookaheads derived from channel propagation latency or protocol characteristics. In wireless networks, these lookaheads are typically short, causing the potential for parallelization and the achievable speedup to remain small. This paper presents Horizon, which unlocks a substantial portion of a simulation model's workload for parallelization by going beyond the traditional lookahead. We show how to augment discrete events with durations to identify a much larger horizon of independent simulation events and efficiently schedule them on multi-core systems. Our evaluation shows that this approach can significantly cut down the runtime of simulations, in particular for complex and accurate models of wireless networks.
