2009年8月,随着‘感知中国’的提出,国内众多学者对无线传感器网络开展了日益深入的研究,而节省网络能耗则是研究的首要问题。主要针对延长传感器网络生存时间、增强网络的可靠性的目标,提出一种自适应区域路由算法(ARRA),它包括对WSN进行区域规划、区域自治以及区域负载均衡三个方面。分析和仿真同时表明,ARRA实现了传感器网络的能量均衡,降低了网络能耗,并能提升某些热点区域的生存周期和可靠性。
In August 2009, with the advent of ’Perceived China’, many scholars in China have conducted more and more in-depth research on WSNs, and saving network energy consumption is the primary issue to be studied. Aiming at the goal of prolonging the lifetime of sensor network and enhancing the reliability of the network, this paper proposes an adaptive regional routing algorithm (ARRA) which includes three aspects: regional planning, regional autonomy and regional load balancing. Analysis and simulation also show that ARRA achieves energy balance of sensor networks, reduces network energy consumption, and enhances the life cycle and reliability of some hot spots.
