Parallel simulation environment for mobile wireless networks

Abstract

A parallel simulator has been designed for the evaluation of wireless, multihop, mobile networks. This

A Novel Approach for Distributed Simulation of Wireless Mobile Systems

“…A wide research work has been done in recent years in the field of tools and methodologies for modeling and efficient simulation of wireless systems [1,2,11,12,13,15,18,20,22]. Among the relevant scenarios considered Cellular systems, PCS networks and the Mobile Ad Hoc Networks (MANETs) are gaining an increasing relevance.…”

“…a Parallel Discrete Event Simulation (PDES) approach [7,8], e.g. Glomosim [22] based on PARSEC [1], Maisie [18], parallel and distributed implementations based on Network Simulator (ns-2) [10,15,16,20] based on RTI-KIT [15], on ANSE/WARPED [14], on TeD [13], USSF over Warped/Notime [Rao99], Wippet [11], SWiMNET [2], and many others [10,12,18]. In order to exploit the maximum level of computation parallelism, many research activities dealt with dynamic balancing of logical processes' executions (both cpu-loads and virtual time-advancing speeds) by trading-off communication, synchronization and speed-up, both in optimistic and conservative approaches [4,5,9,19,21].…”

A New Adaptive Middleware for Parallel and Distributed Simulation of Dynamically Interacting Systems

“…Examples of models challenging currently available simulation systems and tools range from large-scale wireless systems, like cellular, mobile ad hoc and sensor networks, up to biology-inspired models and molecular systems, elementary particles physics and cosmology systems [17,19,20,24,26,31,35,36,37,39]. The simulation-based investigation of complex systems is This work is supported by MIUR FIRB funds, under the project: "Performance Evaluation of Complex Systems: Techniques, Methodologies and Tools" widely adopted and it is often preferred, in practice, to the mathematical intractability and critical model-complexity of alternative numerical and analytical resolution methods [17,25,30,31,35].…”

“…a Parallel Discrete Event Simulation (PDES) approach [1,6,12,13,18,19,20,28,29,31,36,39]. More recently, the distributed simulation community contributed in the definition of a new standard, named IEEE 1516 "Standard for parallel and distributed modeling and simulation" [16].…”
