A Hand-off Management Structure based on OLSR protocol for Wireless Mesh Networks

Wireless Mesh Networks (WMNs) [1] enlarge the wireless coverage area by interconnecting relatively stationary wireless mesh routers (MRs). Under the coverage, mobile nodes (MNs) can move around and connect to nearby MRs. Mobility management is one of the most significant management services for WMNs. In this paper, a Hand-off Management Structure based on OLSR protocol is presented. In this structure, any participation of MNs in the mobility-related signaling is not required. MNs' location information is distributed appropriately so that every MR can quickly recognize the new position of MNs. Significant benefits are shown by the performance analysis.
