Mobile Ad Networks is a class of self configured , infrastructure less networks. It basically represents complex distributed systems comprises wireless mobile nodes that can freely and dynamically self-organize into arbitrary and temporary , “ad-hoc” network topologies. Quality of service support is a very challenging task in MANETs because of time varying link capacity , limited bandwidth , and the most important of all is dynamic topology. Thus when it is even difficult to trace the route between mobile source node and mobile destination node , it actually becomes very difficult to locate and maintain the routes satisfying one or more quality of service constraints. This paper attempts to present some of the prominent Metric and Issues related to Network layer and MAC Layer Then the researchers also proposed a modification to the existing algorithm initially given by Wen-Hwa Liao [4] in the way by merging sending table (STx ) and receiving table (RTx ) per node as merged sending –receiving table ( STRTx ) per node , to further improve the performance of bandwidth reservation QoS routing protocol for mobile ad hoc networks .
