Abstract
NLC-BOP algorithm is proposed for the beacon collision problem in IEEE802.15.4. Beacon collision is divided into direct conflict and indirect conflict and NLC-BOP algorithm is used to solve these two kinds of beacon collision problems. NLC-BOP algorithm based on BOP uses neighbor tables to solve beacon collision. The coordinator establishes 1 hop and 2 hop neighbor tables at MAC layer and allocates the beacon transmitting order for other coordinators at the same time. Finally, the size of the BOPL can be estimated and we make assumption and processing for the coordinator of death and isolation. The simulation results indicate that new algorithm compared with the original algorithm greatly reduces energy consumption, packet loss rate. In the case of guaranteeing delay, it improves the throughput.
