In the contention access period (CAP) of IEEE 802 154 beacon enabled mode collision probability Increases and network performance decreases as the number of contending devices increases In this paper we propose an enhanced contention access mechanism (ECAM) to reduce the collision probability in low rate wireless personal area net works (LR WPANs) In ECAM since the duration of each CAP is divided into multiple sub CAPs the number of devices contending for frame trans missions in each sub CAP can be reduced by approximately one over the number of sub CAPs Further this lowers the probability of collision due to two or more simultaneous frame transmissions In addition since ECAM shortens the channel access duration of devices devices with ECAM have lower power consumption To compare the performance of ECAM with that of the IEEE 802 15 4 standard we carry out extensive simulations The results show that ECAM yields better performance than the IEEE 802 15 4 standard especially for dense networks with a heavy traffic load |
