无线传感器网络中基于节点对链路质量的任务分配.

In order to improve resource utilization efficiency in wireless sensor network, this paper proposed an algorithm to allocate tasks to a pair of collaboratively working sensor nodes based on their link quality. Specifically, it utilized link quality of two collaborative nodes to obtain the ability level of them. Then, allocated each node pair with a task whose task level ( e . g., measured by the computing intensity) could match with the ability level of this node pair, so that each node pair could perform task cooperatively and efficiently. Considering that a node may form different node pairs with multiple nod es, thus allocating redundant tasks( tasks with same task level), algorithm need to adjusted tasks to avoid redundant task execution. Simulation results show that the proposed algorithm can not only improve the task allocation efficiency, but also balance the energy consumption of wireless sensor network. [ABSTRACT FROM AUTHOR]
