Interference Cancellation and Performance Enhancement in Coexistent Heterogeneous Wireless Packet Networks using Packet Transmission Time Sharing

G.M.Tamilselvan, Member, IACSIT, Dr.A.Shanmugam

Abstract—In ubiquitous networking environments, we generally need two or more heterogeneous communication systems coexisting in a single place. Especially, wireless local area networks (WLANs) based on IEEE 802.11 specifications and wireless personal area networks (WPANs) based on IEEE 802.15.4 specifications need to coexist in the same Industrial, Scientific and Medial (ISM) band. If the WPAN communication coverage is expanded using a cluster-tree network topology, then the 802.15.4 network is more susceptible to interference from neighboring WLANs. In this paper, we propose packet transmission management (PTM) scheme for mitigating the interference effects in WPAN. To evaluate the performance of the proposed scheme, the performance metrics such as bit error, throughput, average end-end delay and average jitter is measured using Qualnet 4.5 simulator. The measurement result shows that the proposed scheme is effective in an IEEE 802.15.4 network for various topologies in the presence of multiple IEEE 802.11 interferers.
