Performance Evaluation of Micro-Mobility Protocols in Fail-Tolerant Mesh Networks

This paper describes a terminal´s independent mobility architecture, TIMIP/sMIP, which supports IP mobility of legacy terminals, and presents a complete performance evaluation to compare the proposed architecture with alternative solutions, via simulation studies in complex scenarios featuring wired mesh topologies and wireless disjoint channels. The NS2 simulation studies compare the selected micro mobility protocols under both stationary and moving conditions, but also when random link failures occur in the wired part of the network, which is a previously unstudied scenario. The results show that the TIMIP protocol has the best overall efficiency for handover latency and resources optimization, due to its localized handovers and tree-optimal routing features; and that HMIP has the best robustness to wired link failures, a result its data packets encapsulation feature
