一种能量消耗相关的传感器网络中继节点布局策略

摘要

在传感器网络技术应用的某些领域中,传感器节点位置固定,并且有些距离汇聚节点太远,需要加入中继节点转发数据.如果某些中继节点承担了过多的数据转发量,会过早耗尽能量.从而影响了网络的生存周期.针对该种情况,提出一种实现各节点能量均衡消耗的中继节点多级布局策略,基于该策略,还提出两种能够有效减少中继节点数目的策略:数据的分漉策略和数据的汇集策略.%in some applications of wireless sensor networks, the sensing nodes is so far away from base station that relaying nodes must be employed to forward data. Some relaying nodes use up their power early because they have heavier traffic load, which affects the network lifetime. This paper proposes the multi-phase placement strategy of relaying nodes, which implements an even energy consumption distribution among different nodes. And then, proposes two strategies to reduce the number of relay nodes: streaming data strategy and data pooling strategy.
