Routing in mobile ad hoc networks is based on the cooperation of network's nodes. The presence selfish nodes that do not cooperate this task drastically reduces number delivered packets. In order to find better paths include willing cooperate, we propose a new routing algorithm reputation our proposal, each node locally assigns value rest network and next it uses assigned values out paths, minimize overall packet loss ratio. We assume have stationary behavior, but also mechanism detect...
