New Scheme of Adaptive Zone Routing Protocol

This paper proposed a routing protocol named adaptive Zone Routing Protocol (NSAZRP) that is more stable and has achieved better routing performance than ZRP in Mobile Ad-hoc Networks by taking into consideration that nodes are mobile with a non-uniform speed. NSAZRP allows different nodes to choose different zone radius according to each nodes discrete mobility. NSAZRP modifies the ZRP and speed of the nodes in a MANET can be determined within a reasonable approximation by utilizing the signal strengths received from the neighboring nodes. Three protocols that are used in ZRP i.e. IARP, IERP and BRP are also used in our protocol. Only difference is that the radius of each node will be adapted to the mobility and traffic pattern. Any proactive routing protocol like DSDV can be used as IARP and any reactive routing protocols e.g. DSR, TORA etc can be used as IERP, and BRP will control the flooding of control packets in the network and utilizes the information maintained by IARP to find routes to distinct nodes. Simulation results show that NSAZRP can adapt well to the more complicated and practical Ad hoc applications.
