Performance Evaluation of Multimedia Transmission in MANETs for AODV nthBR Routing Protocol

摘要

A mobile ad hoc network (MANET) is a self-configuring network of several independent nodes with each node acting as a router also. The network can be single hop or multihop and are characterized by frequent node movements. Various MANET applications include military deployment, formation of network in meetings and conferences, electronic classrooms etc. As the popularity of these devices increase, it becomes necessary for these devices to support real time and multimedia applications. These applications require stringent Quality of Service parameters and to support these parameters an efficient routing protocol with back up routing is necessary. The popular reactive routing protocols like AODV and DSR do not have an efficient back up routing system and hence any route failure in such systems makes it difficult for multimedia applications to be supported. In this paper AODV nthBR protocol, which has been proposed and implemented by the author previously for data transmission, is now implemented for multimedia transmission. This paper proposes AODV nthBR routing protocol for transmission of multimedia traffic. AODV nthBR routing protocol provides multiple backup routes in case of a node failure resulting in better QoS parameters for transmission of packets. Here, AODV nthBR has been implemented for transmitting an image and the results are compared with other reactive routing protocols.
