摘要: 针对IEEE 802.15.4网络的MAC层采用基于时隙的CSMA/CA标准算法可能引发数据封包碰撞和网络拥塞的问题,参考ABE算法对标准算法进行了改进,并采用NS-2网络模拟软件对基于时隙的CSMA/CA标准算法与ABE算法对2.4 GHz频段上的IEEE802.15.4星型网络性能进行了模拟实验。结果表明,基于ABE算法的2.4 GHz IEEE 802.15.4网络在网络吞吐量、数据封包成功传输率、网络公平性、LQI类型封包遗失数量等方面的性能都得到了有效提升。

Abstract: 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.
