However, the video streaming in mobile ad hoc network, has still been a challenging task mainly due to its limited bandwidth and constrained energy resource. The bandwidth improvement alone made in the communication links using compression techniques, does not enhance the performance of the network proportionately because of inefficient energy paths which have low residual energy nodes resulting in shorter remaining lifetime. Therefore both bandwidth and energy have to be considered and improved simultaneously for effective streaming in MANET. The video compression technique SVC, an extension of H.264/AVC is used to improve bandwidth of links with Traffic Splitting strategy. To achieve a propagation of improved bandwidth with energy efficient paths through reliable multipath using SVC in non-overlapping zone routing network topology, an Energy Efficient Improved Bandwidth Video Streaming through Reliable Multipath Propagation (EEIB-RMP) protocol has been proposed in this work. It incorporates two algorithms namely Efficient Energy Path (EEP) Algorithm and Prioritized Bandwidth-Energy Path (PBEP) Algorithm. The former is used to find the efficient energy paths of higher hopcount and lower end-to-end delay, and the latter is used to determine the prioritized and improved bandwidth-energy paths from source to destination for establishing reliable propagation. The parameters PDR, Bandwidth Index Ratio and Energy Index Ratio have been used as performance metrics. The performance metrics of the proposed work are compared to those of the other existing multipath protocols SAFAR and MEER using NS 2.34 and the simulation results show that the performances of the proposed system get considerably improved.

I NTRODUCTION mobile ad hoc network (MANET) is typically used in the dynamic environments such as military operations, law enforcement, disaster recovery, emergency search and rescue operations. Digital video communication is a rapidly developing field with a progress made in video coding techniques [1]. Many digital video processing techniques [2] have been used in the multimedia networks for a decade. Such techniques need to be customized for adapting to video streaming applications in MANET. The role of video streaming is very crucial in the applications of MANET. Many issues of video streaming and the techniques to solve them have been discussed in [3]. One of the major issues in video streaming is bandwidth constraint and the bandwidth of MANET cannot be truly improved without managing the energy resources in the network [4]. In multi-path video streaming, the video packets which are propagated through the paths of high bandwidth, always will not offer a better performance since some of the packets may get lost in transition due to inefficient energy paths with the nodes of low residual energy resulting in shorter life time. Therefore, both bandwidth and energy have to be improved simultaneously to achieve appreciable results in the video streaming applications of MANET. This work is proposed to improve bandwidth of links, energy of nodes and reliability of network for effective propagation in video streaming applications of MANET. Bandwidth is like lanes on a highway which allows more traffic to go through at once, while still retaining high speeds. A high bandwidth connection can service many requests and users without sacrificing precious speed. A symptom of a bandwidth problem is always slow network performance. Many times bandwidth is simply increased when a network slows down. However, this is not always a good solution since it adds cost, and merely solves the symptom of the problem, not necessarily the problem itself. In view of improving the bandwidth of the network, different compression techniques have been introduced recently. Video compression techniques are gaining popularity since storage and network bandwidth requirements need to be reduced with compression. The different standards of video compression such as H.261, 263 and 263+, MPEG-1, 2, 4, 7 and H.264/AVC have been explained in [1]. The latest compression technologies, to some extent, have bridged the gap between the voluminous visual data required for video streaming and the limited bandwidth of communication channels. Still the compression technology must be customized and adaptable to video streaming applications in MANET. In that point of view, A
