A mobile Ad Hoc network is a self organized. neworks which is composed of only moblie nodes and which topology is dynamically changed.A mobile Ad Hoc netwoks has no fixed infrastructure in which mobile nodes is both corresponging node and router.Because of its characterisation,it is very important to select routing.In existing routing protocol,these emphasis on uni traffic routing and multi traffic routing isn't taken into consideration.Therefore,we propose a novel multi traffic routing protocol that can support QoS and optimize power consumption.In our proposed protocol,a large power level routing is built up by transmission a large power,and at the same time by immediate node overhearing and redirecting,a optimizing power routing is discovered,at the end different routing is selected to communicate according to traffic class.By compassion with other related routing protocol,our proposed protocol can satisfy practical communication and improve overall integration performance in Ad Hoc networks.

Mobile Ad Hoc Network is collection of wireless mobile hosts forming a temporary and dynamically reconfigurable wireless networks with no fixed infrastructure or central administration. Because its topology is dynamic, its routing protocol is different from other networks. With the efficient support of transmitting data, this paper proposes a new routing protocol based on mobility prediction in mobile ad hoc wireless network. Considering the delay and the stability of the routing path, this protocol picks the steadiest path with the constraint of delay. The results of simulation show that the scheme enables get good network performance with shorter end-to-end delay and higher packet delivery ratio than stable link protocol, but its control overload is almost the same with stable link protocol.
