关于无线传感器网络的路由算法研究，在能量均衡上的经典LEACH算法，用matlab进行的仿真，能够实现！(Abstract: The distributed wireless sensor net work and the technol ogy of wireless communicati on could realize the subsidence monit oring and measuring in coalmine goaf . One of the i mportant researcheswas r outing p r ot ocol in wireless sens or net works . Based on the design idea of the LEACH routing p r ot ocol for the wireless sens or net work, taking the net work communicati on capacity t o be increased and the re2 dundant data trans missi on t o be reduced as the target, according t o the available LEACH i mp r oved calculati on method, an i mp roved layer r outing p rot ocol algorithm was p rovided . With the introducti on of the forced cluster head and according t o the data relativity of the monit o2 ring and measuring variati on for the unit p itch pointswithin the continued ti me, the redundant data transmissi on quantitywas reduced .
