Mobile-Ad-Hoc network is a spontaneous, self configurable network consisting with multiple mobile nodes. All the nodes that are communicating in network acts like router and follow a random, ever-changing topology for sharing data on any scalable scenario. Due to this ever-changing network topology, one of the challenging tasks in multimedia ad-hoc network is to provide Quality of Services (QoS) during streaming transmission. QoS refers as some application oriented parameters that provide some sort of guaranty to any large and scalable network. Improvement of QoS in multimedia streaming is very essential for smooth and effective transmission. This paper composed a variant and QoS resistant scalable network using lossless compression technique over multipath AODV mechanism. The main aspect of this paper is to enhance the streaming rate by improvement of QoS parameters (delay; bandwidth; jitter; packet loss; PDR) by apply Mpeg4 compression. Simulations were carried out in NS-2 and different QoS matrices are evaluated for proposed mechanism. Quantitative results clearly exhibit the performance of the proposed approach over the existing protocols.
