Simulation Tools in Wireless Sensor Networks: Ant Colony Optimization of a Local Routing Algorithm

Wireless Sensor Networks (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, and to cooperatively pass their data through the network. Network Management of such a sensor network is a very big challenge. Also the fast changing nature and the adhoc necessity of the network prevents the choice of a Centralized Solution which can decide the best route to route packets and at the same time minimize the different parameters like congestion, load, etc. Also no single node can take up the job of centralized manager due to the limited energy and processing capabilities of mobile nodes.
