The Problem of Placing Mobility Anchor Points in Wireless Mesh Networks

In English Hierarchical mobility management schemes such as HMIP and cellular-IP have been shown to be effective in providing low latency handoff in mobile networks. In this paper, we investigate the suitability of hierarchical mobility management schemes in Wireless Mesh Networks (WMN) and find that they are not directly suitable since MWNs have graph based topologies rather than tree based topologies. Because of this, there exist no natural locations for Mobility Anchor Points (MAP) sub that sub domains can be formed. In this paper, we present a scheme for finding the optimized placement of MAPs in WMNs, We validate our solution with experiments and argue that with optimized placement of MAPs, HMIP is applicable on WMNs and is able to give a close to optimal packet loss rate and handoff latency which is comparable to the performance of HMIP in fixed networks.
