无线传感器网络中的节点协作算法研究

Collaborative Algorithm in Wireless Sensor Networks

由于受传感器节点存储能量、通信带宽等因素的制约,传统高功耗网络协议无法直接应用在无线传感器网络中。本文根据无线传感器网络的特点,以信息引导技术为研究方法,以最小化能耗为目标,提出了基于信息有效性函数的传感器节点信息协作算法,并通过理论及仿真计算验证该算法的有效性。

Because of some limits such as deficient energy storage and narrow communication bandwidth, the traditional network protocols which consume much energy can not be directly used on wireless sensor networks. With the purpose of overcoming those disadvantages, this paper, which uses the informationdriven method, proposes a algorithm based on information utility function to enhance the collaboration between sensor nodes, and did some experiments to prove the performance of the algorithm.
