Abstract: Mobile ad-hoc network formed by wireless hosts which may be mobile. Ad-hoc network without using apre-existing infrastructure. Routes between nodes may potentially contain multiple hops. In MANET nodes are free to move randomly and organize themselves arbitrarily, thus the network’s wireless topology may change rapidly unpredictably. Due to movement of nodes, QOS(Quality of Service)routing is difficult task in MANET. In this paper from the QOS, we differentiating traffic and services, QOS Provide a higher network PDR, maximum bandwidth, low delay, reduce control-overhead. In this paper we decrease the congestion and path failure during packet forward. Here multipath routes so packet goes to various path then hackers and unauthorized person does not get the packet and routes. By the QOS we increase the PDR and end to end delay, control overhead.

Keywords: QOS (Quality of Service), AODV and R-AODV, PHR-AODV.
