Distributed Energy-balanced Dynamic Packet Forwarding Strategy in WSN

摘要

摘要: 针对无线传感器网络中存在的能量空洞问题，该文提出一种能量均衡的层次型数据转发策略。根据节点可用能量、节点之间相对位置及不同网络区域簇头能量消耗速率构建非均匀层次化结构。进而，综合考虑节点簇内通信开销和节点关系选取中继转发节点，并在多跳簇间数据转发时执行数据融合进一步降低转发数据量以实现簇间多跳通信的能量有效性。数值结果表明，所提机制可以有效地均衡网络负载，延长网络生命周期，改善网络数据转发性能。

Abstract: As for energy hole issue in Wireless Sensor Network (WSN), an energy-balanced dynamic hierarchical data forwarding strategy is proposed. According to the node usable energy, relative position and the energy consumption of cluster head in different area, the unequal hierarchical model is constructed. Furthermore, in order to realize energy efficiency of inter-cluster multi-hop communication, both node energy cost in the phase of inner-cluster communication and node relationship are considered for relay node selection, then the packet compression algorithm, a way to further reduce the forwarding packet, is performed during the process of multi-hop inner-cluster packet forwarding. The numerical results demonstrate that the proposed mechanism can balance the network load effectively, prolong the network lifetime, and improve the performance of network packet forwarding.
