To reduce the delay of channel contention at the Medium Access Control( MAC) layer for IEEE 802. 15. 4networks,a channel contention mechanism for nodes,with unsaturated load is designed. A mathematical model is built and a derivation is carried on to obtain the steady-state probability of the main state. According to the result of the model,the formula of channel access delay is derived based on the modeling of channel state conversion process. The impact of protocol parameters such as λ,NB and min BE on th...
