一种高效节能的无线传感网络动态路由算法

摘要

Wireless sensor network is one of the technologies of the 21st century's most influential. But how to extend the network in a network vitality and reduce the energy consumption is the key, so people need to design a dynamic adaptive routing algorithm is critical. Existing LEACH algorithm based on a dynamic grounds based on rough set algorithm, the algorithm first to predict the load of all nodes in the wireless sensor network,then select an optimal multiple transition path to transmit data during transmission, the high similarity data integration, and eventually reach the base station. The simulation results show that the proposed algorithm and LEACH phase more effectively to reduce and balanced energy depletion,to extend the service life of the network,enhanced data transfer rate.%无线传感网络是21世纪最具有影响力的技术之一.但是这在个网络中如何延长网络生命力和减少能量消耗是关键,所以就需要设计一个动态的、自适应的路由协议算法至关重要.在已存在的LEACH算法的基础上,提出了一种基于粗糙集的动态理由算法,该算法首先预测出无线传感网络中所有节点的负载情况,然后采用多路跳变的方式选择一条最佳路径传送数据,在传送过程中,对于一些相似度极高的数据进行整合,最终到达基站.仿真结果表明,提出的算法和LEACH相比较,更加有效地减少和均衡能量耗损,延长网络使用寿命,强化数据传送率.
