Implementation of Adaptive Mobility Management Technique for Wireless Mesh Network to Handle Internet Packets

摘要

Hybrid Wireless Mesh Protocol (HWMP) has been specified for routing of packets in Wireless Mesh Network (WMN) for IEEE 802.11s. But external STAs' movement is not supported by IEEE 802.11s. There are many existing techniques for managing mobility of mobile nodes. But IEEE 802.11 s is not integrated with any of these techniques. The paper proposes adaptive mobility management technique to support movement of external STA in WMN. The scheme is combined with IEEE 802. 11s. NS-2 has been used to simulate both the schemes. Performance comparison shows that the proposed technique performs better than HWMP in respect of average handoff cost, average end to end delay, normalized routing overhead, and throughput in different network conditions.
