QoS Enhancement using Efficient Routing Protocol for Video over Wireless Adhoc Networks
E. D. Kanmani Ruby, Nehru Kasthuri · 2011
ad hoc network (MANET) is an autonomous system of mobile nodes connected by wireless links. Power failure of a mobile node not only affects the node itself but also its ability to forward packets on behalf of others and hence affects the overall network lifetime especially while multicasting the real time video file in multiple paths over a large number of nodes . Due to network mobility, the power level of nodes gets drained. Therefore it is very difficult to find and maintain an optimal power aware route.The proposed work aims at discovering an efficient power aware routing scheme in MANETs. In this work, a scheme has been proposed to maximize the network lifetime and minimizes the power consumption during the source to destination route establishment. In this paper the routing is performed based on the available power level of nodes. That is, the multiple paths are formed based on average power level of intermediate nodes between source and destination. The path having maximum average power level is selected for routing of packets. Thus the proposed work is aimed to provide efficient power aware routing considering real and non real time data transfer.
