Optimizing Velocity Based Adaptive Zone Routing Protocol

This paper proposed a routing protocol named Optimizing Velocity Based Adaptive Zone Routing Protocol (OVBAZRP) that is more stable and better routing performance in scenarios where mobile nodes move with non-uniform speeds, an Optimizing Velocity Based Adaptive Zone Routing Protocol (OVBAZRP) is proposed which allows different nodes choose different zone radius according to each node´s distinct speeds. In OVBAZRP protocol, the intrazone active routing protocol and bordercast resolution protocol of ZRP are redesigned. Several examination control mechanisms to reduce the routing lookup overhead are also included. OVBAZRP 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 OVBAZRP can adapt well to the more complicated and practical Ad hoc applications.
