L Zhen1, SUN Yan-fei1, LI Ya-jie1, et al. Synthetic optimized routing protocol of wireless sensor networks for coal-mine[J]. 2010, 29(4): 74-77. DOI: 10.13873/j.1000-97872010.04.030.
A synthetic optimized clustering routing protocol is proposed based on the in-depth analysis of special requirements for WSNs in the coal mine safety monitoring.Through the head election mechanism optimized in many aspects
distribution of cluster head and ’hot zone’ problem is improved.Creative "local consultation" strategy is presented and the "overlap" phenomenon is well solved
the node energy is saved in a maximum extent.Simulation and tests show that this routing protocol effectively prolongs the network survival time.
