Abstract

In large-scale, complicated Wireless Sensor Networks, the cooperation among sensor nodes is a key topic, and has been receiving more and more attention. The dynamic coalition mechanism in Multi-Agent System is an important method for this topic, and then an energy-efficient coalition formation algorithm is needed since the energy resource of WSN is restricted. This paper proposes a WSN coalition formation algorithm based on Ant Colony System with dual-negative feedback characteristic. Coalition sponsor inclines to wake those sensor nodes which seldom or never joined coalitions before to form coalition, which can balance the energy consumption among sensor nodes, so as to extend the network lifetime for more tasks. The results of simulation experiment show the validity of this algorithm.
