“…But using little timeout values to avoid stale paths can bound the benefit of using multiple paths. From [16], it is observed that AOMDV outperforms SMR in many aspects like less control overhead, less end to end delay and good packet delivery ratio. So AOMDV is chosen in this work for routing aware purpose.…”

Mobile Ad-hoc Network is capable of clearing lots of challenges involved in the real-world communication. They are used in emergency response schemes, military field operation, oil drilling and mining operations. Transmitting video over MANET is an active research area due to their potential wide spread applications. In the last decade, both mobile and multimedia communications have experienced unequal rapid growth and commercial success. However, transmitting multimedia flows over wireless Ad hoc network remains an extremely challenging issue due to the limited battery lifetime of the wireless nodes. Providing good quality end-to-end video communications over mobile ad-hoc networks is more challenging due to the dynamically changing topology of the ad-hoc networks and the unreliable wireless channels. Multiple Description Coding (MDC) is an effective coding approach to enhance the error resilience of video transmission over any lossy networks. When MDC is combined with multipath transmission, MDC enables traffic dispersion and it alleviates the error propagation caused by the packet losses and hence reduces the network congestion. The error prone nature of the adhoc network always causes the frame to get corrupted. When MDC is used with such a network, it uses these corrupted frames as a reference frame and through motion compensation it compares the current frame with the reference frame and leads to error propagation throughout the network which results in video quality degradation. So, in this work, routing messages of AOMDV is used as the feedback messages after estimating the packet loss in the network and video coding is adapted accordingly with respect to the feedback messages and thus the quality of the received video is improved. AOMDV also saves the energy of the nodes by multipath routing. This work deals with comparing video quality using MDC, MDC with feedback based SMR (Split Multipath Routing) and MDC with feedback based AOMDV (Ad-hoc On demand Multipath Distance Vector routing). The experiment has been conducted using NS2 simulator along with EvalVid for evaluating the video quality. The results demonstrate that MDC with feedback based AOMDV gives good PSNR value under different packet loss rate and guarantees good video quality for large number of users in the network and at the same time the PSNR is examined by varying the number of nodes in the network resulting in decreased PSNR while trying to increase the number of nodes involved in the network.

“…Multicast is an essential technology for many applications such as video distribution and group video conferencing, and results in bandwidth and power savings as compared to multiple unicast sessions. Many researches over the last several years have focused on unicast and multicast video transmission over wireless ad hoc networks (Wei & Zakhor, 2007;Agrawal et al, 2006;Chow & Ishii, 2008;Mao, Hou, Cheng, Sherali, Midkiff & Zhang, 2006;Mao et al, 2003). The main objective of these researches is to improve the quality of the received video by exploiting the error resilience properties of MDC along with multiple paths.…”

“…Such capability gives GA the unique strength in identifying promising regions of search space, rather than getting trapped in local optimum. A GA-based approach [4] represents a chromosome as a path, which consists of a sequence of genes (nodes). At each iteration a number of genetic operators are applied to the current individuals to generate individuals for the next generation.…”

Real-time multimedia transport has stringent bandwidth, delay and loss requirements. Providing support for such applications in infrastructure-based single hop wireless networks is a great challenge. Since mobile networks are characterized by host mobility, providing continuous streaming service in such an environment is an uphill task. In order to achieve continuous multimedia streaming, we propose an innovative multipath architecture for multimedia streaming. Existing multipath architectures are not efficient for mobile networks, where, in addition to normal streaming requirements, we need to handle the frequently occurring hand-offs. In our architecture, multiple paths, identified using an efficient genetic algorithm, are used to provide robust streaming in case of link failures. Dynamic encoding schemes are used in the server to adapt according to network conditions based on the feedback received from the network. In addition, hand-offs are predicted proactively and mobile agents containing the buffered data are migrated to the predicted base station. Altogether, the architecture provides robust multimedia streaming service under varying network conditions. We have simulated the performance of our architecture using Network Simulator (NS -2) and the results are promising.
