摘要
为了进一步降低无线传感器网络数据传输过程的能耗,在深入研究和分析PEGASIS协议及其相关改进算法的基础上,提出了一种能耗均衡的无线传感器网络路由算法(Energy Balance-PEGASIS,EB-PEGASIS)。该算法通过将网络区域划分为若干等宽的子区域,每个子区域内的所有节点形成一个链,由链首节点负责与基站通信。针对链首节点能量消耗太大有可能过早死亡的问题,提出采用链首节点轮换的方法来均衡和降低能量消耗,提高数据传输效率。在MATLAB中实验仿真结果证明,与PEGASIS算法相比,EB-PEGASIS算法将首个节点的死亡时间延长了2.9倍,在降低和均衡能量消耗等方面均具有较好的性能。
Based on the study and the analysis of PEGASIS protocol and its improved algorithm, a new algorithm named EB-PEGASIS is proposed to achieve further energy saving in the process of the wireless sensor network data transmission. The EB-PEGASIS divides the network area into some even sub-zones, all nodes in each sub-zone construct a data transmission chain. The leader-node is responsible for the communication with the base station. In order to reduce the amount of the leader-node energy cost and balance the energy consumption, the idea that the network can alternate the leader-nodes to the efficiency of data transmission is presented. Compared with PEGASIS algorithm, the simulation results in MATLAB show that EB-PEGASIS algorithm prolongs the first node death time to 2.9 times, and has better performance in reducing and balancing the energy consumption.
