CHMA: A Congestion Mitigation Algorithm Based on Hotspot Cluster in Ad Hoc Networks
This paper proposes a congestion mitigation algorithm based on hotspot cluster (CHMA), which provides a novel routing approach to mitigating congestion in ad hoc networks.CHMA defines hotspot cluster to represent highly congested region which is identified according to nodes MAC delay and buffer occupancy, then finds an efficient path quickly to avoid the congested region and decrease load of congested nodes. A performance analysis, including packet delivery rate in different MAC delay and buffer occupancy, is given. Simulation results show that CHMA algorithm can mitigate congestion and improve ratio of end-to-end packet delivery in ad hoc networks.
