摘要: 在无线传感器网络中,保障数据传输的端到端可靠性,同时减少节点电池能量消耗,延长网络总的寿命,已经成为路由协议性能评价的重要方面.首先对传感器网络的生存周期建立优化模型,并以此为依据对ETX路由度量存在的不足之处进行了改进,采用能量分级的策略,提出了一种能量均衡的可靠路由度量——EBRM.NS-2仿真试验表明,该度量方法能够有效地延长网络的生存周期,同时也能够确保高可靠的端到端传输,更加适合于无线传感器网络的应用.

Abstract: Ensuring the end-to-end data transfer reliability, decreasing energy cost of batteries and prolonging the network lifetime have been the important factors for routing protocol design in wireless sensor networks. After developing an optimization model of lifetime, the disadvantage of ETX metric is analyzed and overcome by introducing an energy-balanced reliable routing metric-EBRM which is based on the strategy of energy hierarchy. Simulation test on NS-2 shows that the EBRM, which can prolong network lifetime effectively and ensure reliable end-to-end transfer, is more suitable for the application of wireless sensor networks.
