改进的无线传感器网络路由算法
|
摘要
无线传感器网络(WSNs)节点部署的分散性以及节点本身的资源有限性要求WSNs路由算法必须满足低成本、低功耗的设计原则。对包括Cluster-Tree,AODV,LEACH和RPL在内的多种WSNs路由算法进行了对比分析,并以节点间的传输距离和节点剩余能量为度量单位,采用能量均衡策略对RPL算法进行了改进。在Cooja仿真环境下,构建不同节点数的网络,进行了仿真测试,验证了提出的路由算法能够延长网络的生命周期。
The dispersion of the wireless sensor networks( WSNs) node deployment,as well as own resources limitation of node require the WSNs routing algorithm must meet design principles of low cost and low power consumption. Various WSNs routing algorithms including Cluster-Tree,AODV,LEACH and RPL,are compared and analyzed. Using transmission distance between nodes and residual energy of node as unit of measurement,RPL algorithm is improved by using energy balance strategy. In cooja simulation environment,the network with different number of nodes is constructed,and the improved routing algorithm is used for simulation and test,which proves that this routing algorithm can prolong the life cycle of the network.
