A Mobile-Agent-Based Role Switching Management Mechanism in WSN

Aiming at the problem of limited resource and unbalanced load in WSN, the paper proposes a novel role switching management mechanism by importing mobile agent. The sensor nodes can be scattered freely, which adapt actual military situation. We design a mobile agent immigrating randomly and working method among inner-cluster and inter-cluster, meanwhile put forward ´inner-cluster role table´ and ´inter-cluster role table´. Finally it gives the implementation of hardware design and software design. The result shows this mechanism is viable and efficient.
