A cluster-based negotiation model for task allocation in Wireless Sensor Network

This paper studies task allocation in cluster-based Wireless Sensor Network (WSN) using negotiation model. We study both the negotiation reasoning model and the negotiation protocol for task allocation to achieve energy efficiency while balancing nodes energy. Reasoning model determines the offer generate scheme and gives control over negotiation process. A time depending Boulware function is used as the concession strategy in reasoning model to balancing efficiency and utility. Contract net protocol is used as negotiation protocol to regulate the interaction style of nodes. The goals of this study are: 1) energy efficiency task allocation; 2) maintaining energy balance of nodes in WSN after the task to prolong the network life cycle. Experimental results using this cluster-based negotiation model task allocation approach verify its performance.
