GPS Based Distributed Routing Algorithms for Wireless Networks

Free registration required

Executive Summary

Recently, several fully distributed (localized) GPS based routing protocols for a Mobile Ad hoc NETwork (MANET) were reported in literature. They are variations of directional (DIR) routing methods, in which node A (the source or intermediate node) transmits a message m to several neighbors whose direction is closest to the direction of D. Authors also found an older, MFR (most forward progress within radius) method. Authors propose a new location based GEographic DIstance Routing (GEDIR) algorithm. When node A wants to send m to node D, it forwards m to its neighbor C which is closest to D among all neighbors of A and C.
