Velocity based adaptive zone routing protocol

To gain a more stable and better routing performance of ZRP in Ad hoc scenarios where mobile nodes move with non-uniform mobility, a velocity based adaptive zone routing protocol (VBAZRP) is proposed which allows different nodes choose different zone radius according to each node´s distinct mobility. VBAZRP modifies the protocols of ZRP, and presents a new IARP named VBA-IA which uses asymmetric request and reply mechanism and symmetric mutual update mechanism to maintain node´s routing zone proactively and a new BRP named VBA -B which can forward routing query efficiently outside zones by using relationship of nodes. Simulation results show that VBAZRP can adapt well to the more complicated and practical ad hoc applications.
