稳定高效节能且邻近相关的网络拓扑协议

Steady Energy-Efficient and Neighborhood-Relative Topology Protocol

现有的无线传感器网络拓扑协议未全面考虑节点位置、休眠、剩余能量的影响,且依赖于GPS等基础设施获得节点绝对位置,导致网络成本高,能量有效性不足。该文在DEAC协议的基础上,提出了一种分布、稳定、高效节能和利用邻近相关信息数据融合及节点休眠策略的无线传感器网络拓扑控制协议(SEENRT)。该协议利用剩余能量信息,平均各节点能耗负担;利用邻近相关信息和节点休眠,降低覆盖冗余,减少网络能耗。试验结果表明SEENRT协议和LEACH、HEED和DEAC协议相比,能有效地降低网络能耗、平均节点的负担及延长网络的生存时间。

Based on distributed energy-efficient adaptive clustering （DEAC）, this paper presents a new WSN node-location-irrespective topology protocol, named SEENRT. In this protocol, node location, Sleep, residual energy, and cost of WSN are sufficiently considered. This protocol uses the residual energy information to average the burden of the node energy consumption and uses neighborhood-relative information and node sleep to reduce coverage redundancy and WSN energy consumption. The result of test shows that SEENRT protocol is more effective in energy efficiency.
