Smooth Mobility and Link Reliability-Based Optimized Link State Routing Scheme for MANETs

Link reliability metrics are of great significance in routing design for mobile ad hoc networks (MANETs). In this letter, we propose a novel optimized link state routing (OLSR) scheme named smooth mobility and link reliability-based OLSR (SMLR_OLSR). It is implemented on the basis of a prudentially designed semi-Markov smooth and complexity restricted mobility model, which complies sufficiently with realistic node behaviors and is typically used for reliability-enhanced multi-point relay (MPR) selection in SMLR_OLSR. Simulation results show that the proposed scheme ensures an accurate performance analysis, and can achieve longer MPR lifetime and less control overhead.
