摘要: 为降低能耗,延长输电线路监测网络传感器寿命,提出一种新的媒体接入控制与路由联合优化策略。构建无线传感网通信框架,并基于该框架给出一种自适应的簇内调度策略,旨在减少传感器节点的空闲监听,从而降低节点能耗。给出一种按需路由协议,在确保能量等级和信道质量的同时在簇间进行最佳路由选择,基于簇头剩余能量及其到基站的距离,利用非均匀簇技术平衡节点能量分布,延长网络寿命,并构建能耗和延迟模型进行性能评估。实验结果表明,该方案在节能的同时能够显著降低数据传输时延。

Abstract: In order to reduce energy consumption and extend the life of sensors in the transmission line monitoring network,this paper proposes a joint optimization strategy for media access control and routing.A Wireless Sensor Network(WSN) communication framework is constructed,based on which an adaptive intra-cluster scheduling strategy is given to reduce the idle monitoring of sensor nodes and thereby to reduce the energy consumption of nodes.An on-demand routing protocol is proposed to ensure optimal inter-cluster routing selection based on energy level and channel quality.With consideration of both the residual energy of cluster head and the distance from cluster head to base station,the non-uniform cluster technology is used to balance the node energy distribution,which prolongs network lifetime.Energy consumption and delay models are constructed for performance evaluation. Experimental results show that the scheme can significantly reduce the data transmission delay while saving energy.

Key words: Wireless Sensor Network(WSN), low energy consumption, delay performance, multi-hop communications, cross-layer optimization
