Path Reliability of Multi Path Routing in MANET

Mobile Ad-hoc networks are more likely to link failures as it is not supported by a static infrastructure. The path for data transfer can be selected on the basis of many metrics like least hop counts, bandwidth quality of the path, residual life time of path etc. Most of routing protocols address selection of paths based on least hops counts of path. This paper estimates the reliability of the paths (multipath) quantitatively wherein the route selection is done on the basis of residual lifetime of the routes. Reliability of the path is computed using the residual life time of each link of the path. The residual life of a link is computed on the basis of current relative velocity and radial distance between two nodes
