Simulation Research of 2.4 GHz IEEE 802.15.4 Network Based on ABE Algorithm

For problems of data-package collision and network degradation caused by slotted CSMA/CA standard algorithm used in MAC layer of IEEE 802.15.4 network, the paper used ABE algorithm to improve the standard algorithm, and used NS-2 software to simulate performances of 2.4 GHz IEEE 802.15.4 network based on slotted CSMA/CA standard algorithm and ABE algorithm separately. The simulation results showed an overall improvement in network performances of throughput, successful delivery ratio of data-package, fairness and drops number of LQI data-package.
