Many routing protocols have been designed for ad hoc networks. However, most of these kinds of protocols are not able to react fast enough to maintain routing. This paper presents a Proposed Routing Protocol (PRP) that repairs the broken route by using information provided by nodes overhearing the main route communication. When links go down, the authors protocol intelligently replaces these failed links or nodes with backup ones that are adjacent to the main route. Experimental results show that their protocol finds a backup route around 50% of cases and achieve better performance in term of the packet delivery rate than the major ad hoc routing protocols, but with much less overhead.
