ABSTRACT

The routing in Mobile Ad hoc Network (MANET) is a critical task due to dynamic topology. Many routing protocols were proposed which are categorized as proactive and reactive routing protocols. Route maintenance is a great challenge in MANET due to frequent link failure which causes high data loss and delay. To counter such problems, lots of link repair mechanisms were proposed, but all these have their own limitations. This paper proposes a novel routing algorithm for route maintenance based on link failure localization called DSR-LFL. DSR-LFL takes decision on the basis of location of failure link in source route. Proposed algorithm may improve the packet salvaging, delivery ratio and performance of DSR.
