A new multi-objective routing protocol of ad hoc based on routing constrains

For the most existing MAODV protocol is only improved by a single performance, there is a problem that the comprehensive performance of the protocol cannot be improved as well. By uses of the routing selection mechanism with the constraints of bandwidth, delay and packet loss rate of the original protocol, a new multi-objective routing protocol RCQ-MAODV of mobile ad hoc network is put forward. Simulations are conducted to MAODV protocol and RCQ-MAODV by NS2, the simulation results show that RCQ-MAODV routing performance has greatly improved than MAODV, its transmission rate, delivery rate is increased and the network cost is greatly reduced. This shows that the RCQ-MAODV protocol can provide more comprehensive quality assurance for mobile ad hoc networks.
