Link Lifetime-Based Segment-by-Segment Routing Protocol in MANETs

Abstract

Node mobility is one of the most important factors that may degrade network performance and restrict network scalability in mobile ad hoc networks. An effective way to reduce the impact of node mobility is to select long lifetime routing paths in the network. We propose a link lifetime-based segment-by-segment routing protocol (LL-SSR) in mobile ad hoc networks, where each node maintains a routing table for its k-hop region. Simulation studies show that LL-SSR has better scalability and higher packet delivery ratio when compared with GPSR.
