摘要

能量问题是无线传感器网络中需要考虑的一个重要问题。由于网络中的传感器节点使用有限的电池源,导致其使用寿命有限。同时,由于传感器节点采用多跳通信方式,因此汇聚节点附近的节点比更远的节点传输更多的数据。这些现象导致的能量空穴问题是延长传感器网络寿命的关键问题。为此,我们提出了节能、低复杂度的绕行方案,以提前预防能量空洞问题。为了改善无线传感器网络的工作环境,在工作中采用了能量收集技术。虽然能量收集源收取的能量并不总是足以满足无线传感器网络的需求,但所提出的方案可以很好地满足网络的生命周期。该方法可以推迟能量洞的产生时间,延长网络寿命。

Low complexity energy-hole detouring scheme with energy harvesting
Energy problem is an important consideration in wireless sensor network. It is because sensor nodes in network use limited battery source which leads to limited lifetime. Also, sensor nodes in WSNs use multi-hop communication, so nodes near sink node transmit more data compared with farther nodes. These phenomenon results in energy hole problem which is critical to prolong lifetime of sensor network. So We proposed energy efficient and low complexity detouring scheme to prevent energy hole problem in advance. For better environment of WSN, energy harvesting technology is used in this work. Although the amount of energy charged by energy harvest sources is not always enough to meet the requirement of WSNs, proposed scheme can be good at lifetime of network. With this method, beginning time of energy hole can be postponed and it will network lifetime more extended.
