New AODV Routing Protocol with Break Avoidance

Many routing protocols in mobile ad-hoc networks have been developed by many researchers. One of ad-hoc routing protocol types is the on-demand routing that establishes a route to a destination node only when required. However, most of on-demand routing protocols reestablish a new route after a route break. In this paper, we propose a new route maintenance algorithm to avoid route breaks because each intermediate node on an active route detects a danger of a link break to an upstream node and reestablishes a new route before a route break. We propose this algorithm based on AODV) [2], [3].
