An ad hoc network is a collection of mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. Several routing protocols have been proposed for ad hoc networks and prominent among them are Ad hoc On Demand Distance Vector Routing (AODV) and Dynamic Source Routing (DSR). Effort has been made to merge software Quality assurance parameters to adhoc networks to achieve desired results. This Paper analyses the performance of AODV and DSR routing protocols for the quality assurance metrics. The performance differentials of AODV and DSR protocols are analyzed using NS-2 simulator and compared in terms of quality assurance metrics applied.

The objective of this work is to improve the performance of a MANET multi-path routing protocol without increasing or decreasing its default transmission range of the nodes. The proposed work is to control the routing process and only allow hops with maximum possible distances in a route based on the received signal strength at each node. We propose topology aware and power aware ad hoc on-demand multipath distance vector routing protocol based on the
maximum transmission range. We call this model as AOMDV_RR Range Routing and implemented it under ns2 by improving the standard AOMDV protocol. We studied the proposed AOMDV_RR and the standard AOMDV under different network densities and measured the performance for suitable metrics. Measurable difference in performance was realized and the proposed AOMDV_RR performed better than normal AOMDV with respect to metrics network overhead, throughput and energy consumption.
