QOS on multimedia streaming using compression in MANET

Abstract

Mobile ad-hoc networks are spontaneous, on the fly, self adaptive networks. Every mobile node acts as route. Data is transmitted from host to destination through an ever changing network topology. In recent day's scenario multimedia streaming one of the important challenging tasks in Mobile ad hoc network (MANET) as it affects the Quality-Of-Services (QOS) of the network as it needs more bandwidth for smooth transmission of data. The QOS constraints of the network that includes minimum delay, maximum bandwidth and effective throughput for real time multimedia streaming needs to be enhanced. Ad-hoc on demand Distance Vector Multipath routing (AOMDV) protocol is used on Mac layer or in network layer for frequent and constant streaming of audio, video and text type of data. This work proposes a new approach of data compression with Ad-hoc on demand multipath distance vector (AOMDVc) to enhance the QOS of the network. Simulations were carried out by Network simulator tool (NS2) and measure the effective minimization of end to end delay and improvement of throughput of the network and results were compared with existing techniques. Results clearly exhibit the performance of the proposed approach over the existing protocols.
