A Location Update Scheme Using Multi-Hop Pointer Forwarding in Low-Rate Wireless Mesh Networks
Recently, a Pointer Forwarding Scheme (PFS) was proposed to reduce location update overhead in wireless mesh networks. Using the PFS, location update is replaced with a simple forwarding pointer setup between two neighboring MRs until the forwarding chain K is less than or equal to the configurable parameter K-max for each MC. However, in PFS, if the two MRs are not one hop neighbors, the PFS fails to set up a forwarding pointer, and a location update event must be triggered, increasing location update overhead. To improve PFS, the authors present a novel location update scheme called a Multi-hop Pointer Forwarding Scheme (MPFS).
