CoSMoS -: Communication scenario and mobility scenario generator for mobile ad-hoc networks

One of the most important components of mobile ad-hoc network simulations is the mobility model, since it defines the movement of mobile nodes and thus the network topology which in turn affects the performance of the ad-hoc network, e.g. the performance of routing algorithms changes with the mobility model. In this paper we introduce a communication and,nobility scenario generator for mobile multi-hop adhoc networks. The goal is to aid researchers in the design of 'realistic' simulation scenarios which emulate real cities. Our approach combines a wide variety of well understood random mobility models with a, graph based zone model, where each zone has its own mobility model. The combination of directed, weighted graphs, where the weights correspond to the flow of mobile nodes among zones, and zones with different mobility models, allows the researcher design more realistic simulation scenarios.
