The node failure management is a puzzling task in Mobile Ad hoc Networks because of its dynamic nature . Even a single node or link failure can collapse the entire network. The source nodes are taking all responsibilities to manage node failures in the existing systems, but a link failure could be dealt dynamically with the help of alternative paths to deliver payloads without disturbing the source node. The end to end delay and the population of routing packets could be reduced enormously with an effective node failure management at intermediate level. The payload buffering at intermediate nodes need a special attention to decide the optimal buffer size . Here we propose a novel idea to handle node failures at run time to improve the following factors - high packet delivery ratio , low jitter effect and optimized usage of buffer space in mobile devices.
