Abstract

In order to reduce the packet lost rate in 802.15.4MAC layer, this paper raised a model of channel competition mechanism based on Markov chain by analyzing the reason of packet loss rate. Then, throught the mathematical derivations of the steady-state probability on the network transmission, backoff and the channel detection state based on the model of channel access, this paper discussed the formulas of channel collision and the frame packet lost rate. Finally, this paper studied the impact of protocol parameters such as packet arrival rate, the number of nodes, bit error rate, backoff exponent, and number of backoffs on the collision probability and the packet lost rate. Experimental results show that, compared with IEEE 802.15.4 network without node sleep state, the packet lost rate is reduced by 23.7%. And the model describes the MAC layer channel access mechanism very well, and reasonable settings for parameters can optimize the frame packet lost rate. The research outcome can provide reference for the reliable transmission optimization in the practical application of wireless sensor network.
