Delay-constrained video applications have stringent bandwidth, delay and loss requirements, which is a great challenge to support such real-time applications in wireless ad hoc networks. In this paper, to minimize the distortion of video received at the decoder, we propose a cross layer design (CLD) approach which combines the network layer and MAC layer to meet the stringent requirements by dynamically...
Existing on demand routing protocols for MANET's use shortest path as the routing metric, which leads to overuse of an existing path thereby creating hot spots leading to congestion and packet loss. Hence it is important for a routing protocol to adapt to increasing load conditions by timely estimating the load and avoid such congested nodes during route formation. Estimating the load is difficult...
The performance of networks is generally estimated through characteristic indices such as delivery ratio, latency, delay, jitter and loss. Such indices depend on network parameters such as TTL, buffer size, time and load which are at times highly correlated. Factors impacting network measurements include cross traffic, architectures of intermediate nodes, complex interaction of hardware resources...
