Abstract

Persistent sensing requires sensor nodes to keep functioning for a longer duration. Different amounts of incoming packets on some sensor nodes after deployment lead them to deplete their energy faster compared to other nodes without sending the information about their death to the sink node. It results in the formation of energy holes in the network and hence packet loss problem starts. In this study, this problem is overcome by prior notification to the sink about scarcity of resources by setting a dynamic threshold and also, packet delivery is sustained by using a fault tolerance strategy. Simulation analysis shows that proposed work is doing better in terms of packet delivery ratio and number of dead nodes. Also, network lifetime of the proposed work is found to be 73% of the total time duration while its competitor approach has network lifetime 64%.

改进的无线传感器网络能量消耗区域容错最优路由重构方法

持久感知需要传感器节点在更长的时间内保持功能。在部署后，一些传感器节点上传入的数据包数量不同，导致它们比其他节点更快地消耗能量，而不会向sink节点发送有关它们死亡的信息。它导致网络中形成能量空洞，从而产生丢包问题。在本研究中，通过设置动态阈值提前通知sink资源的稀缺性来克服这个问题，并且使用容错策略来维持数据包的传递。仿真分析表明，该算法在数据包传输率和死节点数方面都取得了较好的效果。此外，发现所提议工作的网络生命周期为总时间持续时间的73%，而其竞争对手的网络生命周期为64%。
