Abstract
Wireless Mesh Network (WMN) is one of the major technologies
for the 4G high-speed mobile network. In the WMN, a mesh backhaul connects the WMN with Internet, and mesh access points (MAPs) provide wireless network access service to mobile stations (MSs). The mesh nodes (MNs) (including mesh backhaul and MAPs) are stationary and connected through the wireless mesh links. Due to MS mobility in WMN, Mobility Management (MM) is required to efficiently and correctly route the packets to MSs in WMN. We propose an MM mechanism named Wireless mesh Mobility Management (WMM). The WMM adopts the location cache approach where MNs cache the MS's location information while routing the data for the MS. The MM is exercised when MNs routes the packets. We implement the WMM and conduct an analytical model and simulation experiments to investigate the performance of WMM. We compare the signaling and routing cost between WMM and other existing MM protocols. Our study shows that WMM has light overhead and low implementation cost.
