Research and implementation of a self-organizing network dynamic timeslot channel allocation mechanism

Aimed at the problem of hiding side and channel interference in wireless sensor network communication, a self-adaptively accessing network mechanism which nodes always choose LQI optimal network to access is proposed. On the basis of DSME network, getting the strongest anti-interference channel sequence by using greedy algorithms and avoiding interference through the sequence of timeslot based on dynamic interference channel jump channel to improve the anti-interference of the network. Test results show that under the environment of the new system, the packet loss rate of the network was greatly reduced, and network nodes got the ability of self-healing. It verified the correctness and feasibility of the new method.
