Research of Anti-collision Algorithm for Personnel Position System of Coal Mine Underground Based on WS

According to actual requirements of personnel position system of coal mine underground,the paper studied collision problem of multi-sensor nodes of asynchronous status of wireless sensor networks under low-power.It gave design and implementation of first listening later sending algorithm,time slice scheduling algorithm and consecutive misreading filter algorithm by single-chip microcomputer(programming.) The experiment result showed that the consecutive misreading filter algorithm was simple and(practical,) and could solve the collision problem efficiently under low-power.
