Abstract To deal with dynamic network topology in Mobile Ad hoc NETworks (MANETs), a reliability-enhanced multipath source routing algorithm is proposed based on accurate path stability estimation. In order to eliminate theoretical errors existing in current approaches, statistical properties of residual path lifetime are exploited by fully introducing correlation among neighboring links’ residual link lifetime. Optimized link and path stability metric is then provided to realize a multipath-enabled routing discovery procedure and a backup path-support fast routing recovery mechanism. Simulation results show that the proposed routing algorithm can achieve fast routing discovery convergence, increase network throughput, reduce data transmission delay, and lower routing overhead. Furthermore, high network reliability can be well guaranteed even under high node mobility degree.
