Abstract: We propose a congestion-based extension to existing multipath routing protocol AOMDV (CA-AOMDV). AOMDV is based on minimum number of hops count between source and destination nodes and is not suitable for real time applications because of its high end to end delay, jitter and packet loss. CA-AOMDV selects a least congested path instead of minimum number of hops between source and destination nodes. CA-AOMDV performs well under high load and varying mobility conditions. In CA-AOMDV, end to end delay is improved by 20%-80%, jitter is reduced by 25%-47%, routing overheads is reduced by 40%-70%. CA-AOMDV performs better than AOMDV in real time applications.

Keywords: mobile ad hoc networks; MANETs; multipath routing protocols; congestion level; quality of service; QoS; real time applications; queuing delay; congestion awareness; AOMDV; jitter; routing overheads.
