摘要
在无线传感器网络中,现有的路由协议是基于静态位置数据路径的多播协议,路由路径的节点可能由于能源耗尽而死亡,因而缩短网络的生命周期。首先提出了一种动态位置的多播协议,以通过改变路由路径来平衡网络能耗,从而延长无线传感器网络的生命周期。此改进的协议平衡了能源,但信号的干扰是主要问题,因此有必要研究干扰的影响并给出对策。于是首次在此基础上引进了MR防干扰方法,增强了路由性能。仿真证明了基于MR防干扰下的高效能多播路由协议在能源消耗和抗干扰两个方面的性能改进。这特别适合于受干扰范围大的情况下又要求平衡能源消耗的情形,符合当前的研究趋势。
In wireless sensor networks,the existing location-based multicast protocols through the static data path,routing path nodes may die because of energy depletion,thereby shortening the lifetime of the network.The paper presents firstly a dynamic multicast location protocol by changing the routing path to balance the energy consumption,thereby extending the lifetime of wireless sensor network.The protocol has balanced energy,but the signal interference is a major problem,therefore,it is necessary to study the effects of interference and get a measure.In the application the MR anti-interference method is introduced where expanded its superiority,which enhanced routing performance.The simulation proved that MR-based anti-interference of high-performance multicast routing protocol improves the routing performance in energy consumption and anti-jamming.This is particularly suited to the situation of bad interference and requirements of balancing energy consumption,especially in line with the current research trends.
