Abstract:
In this paper, the multi-agent technology is applied in wireless sensor networks domain in order to adapt software architecture, and to optimize its performance in monitoring. We explore in particular the issues of topology control, especially some related work using multi-agent systems. In the third part, we will propose an agent-based algorithm for fault tolerance and topology control in a wireless sensor network. Our proposal consists of embedding an agent at each node that is responsible for selecting its parent or the next hop to the sink when transferring packets. The main contribution is the proposal of a new process of changing parent, which is based on the computation of a fault tolerance degree, calculated each time by the agent in cooperation with its neighboring nodes. Several parameters are exploited to calculate this metric, such as the number of hops, the energy and the quality of links. Simulation results show that this method of changing parent allows an enhanced lifetime, as well as network fault tolerance, when compared with the collection tree protocol.
