Simulation of Large Wireless Sensor Networks using Cell-DEVS

The advancement of electronic sensing devices, microcomputers and wireless communication devices has lead to creation of new smart sensors, which can monitor actuate, compute and communicate. Typically, these sensors are deployed in non-deterministic mode (randomly) when deployed in large numbers. These sensor devices have the capability to self-organize into the so-called Wireless Sensor Networks (WSN). WSN are ad-hoc networks, consisting of these spatially distributed sensing and processing devices. We introduce a model and a simulation study of these Large Wireless Sensor Networks (WSN) by implementing the Topology Control Algorithm. We use the Cell-DEVS formalism, which enables efficient execution of cellular models. Thereafter, we observe and evaluate the behavior of sensor nodes and entire WSN from the simulation results obtained, under different test scenarios.
