无线传感网络技术应用于矿井安全监控是当前研究的热点之一。由于传感器节点的能量是有限的,节能优化技术是无线传感器路由研究的一个热点问题。为了延长整个传感器网络的存活时间及保证数据传输的实时性,提出了一种新的路由度量标准,它综合考虑链路质量,能量及传输时延。并基于此路由度量标准,提出了一种候选集选择算法和节点协调机制。仿真实验验证所提出的机会路由算法的有效性,相比于传统的机会路由,可以获得更好的网络性能。
Wireless sensor network technology used in mine safety monitoring is one of the hot spots in current research. As the energy of sensor nodes is limited, energy-saving optimization technology is a hot issue in the research of wireless sensor routing. In order to prolong the survival time of the whole sensor network and ensure the real-time performance of data transmission, a new routing metric is proposed, which considers link quality, energy and transmission delay. Based on this routing metric, a candidate set selection algorithm and node coordination mechanism are proposed. The simulation results show that the proposed routing algorithm is effective and can get better network performance than the traditional routing.
