A Two-way Route Repair Scheme Based on Hop-count

摘要

Considering the limitations of one-way route repair in Mobile Ad Hoc Networks, this paper proposes a novel two-way route repair scheme based on hop-count. This scheme takes the hop differences between the backward and forward node near the broken link as judging rules which decide the direction to repair and thereby shortens the distances of routing maintenance effectively. The simulation results show that the scheme has a better performance in end-to-end packet delay and control overhead than the previous schemes.
