基于能耗均衡的无线传感器路由算法

为了延长无线传感器的使用寿命,弥补传统路由算法的不足,提出一种基于能耗均衡的无线传感器路由算法。首先,分析了无线传感器节点能量的消耗过程,建立了源节点到目的节点的路由表；然后,通过单跳消息方式确定每一个传感器节点的相邻节点,并把剩余能量信息传递给其相邻节点；最后,根据蚁群算法中的信息素浓度与局部能量来选择无线传感器传输数据时的下一跳节点。通过具体实验对其性能进行了测试,实验结果表明,该算法能耗低,保证了能耗均衡,最大程度地延长了传感器节点的寿命。

Wireless Sensor Routing Algorithm Based on Energy Balance

In order to improve the service life of wireless sensor and make up for the shortcomings of traditional routing algorithms,a wireless sensor routing algorithm based on energy balance was proposed.Firstly,the energy consumption process of wireless sensor node is analyzed, and the routing table from source node to destination node is built.Secondly,all nodes need to jump through a single message to determine its adjacent nodes,and the remaining energy information will be deliveried to its adjacent nodes.Finally,according to the concentration of pheromone in ant-colony algorithm and local energy,the next hop node of transmitting data for wireless sensor is selected.The experimental results show that the proposed algorithm has low energy consumption,ensures energy comsuption balance,and extends the lifetime of wireless senser nodes.
