Recovering extra routes with the path from loop recovery protocol

Abstract

Reactive routing protocols for ad hoc networks typically flood the network with request packets, but only discover one route from the network flood. Multipath routing protocols have been proposed to increase the efficiency of request flooding by discovering several routes from one request flood. A novel routing protocol, Path From Loop Recovery (PFLR), is proposed which recovers additional link-disjoint routes from topological loops. PFLR operates as a sub-layer beneath either a single or multipath reactive route discovery protocol. Simulation studies have revealed that the PFLR protocol is at its most efficient when recovering additional paths from small topological loops. © Springer-Verlag Berlin Heidelberg 2005.
