A congestion based extension to existing multipath routing protocol Congestion Aware AOMDV (CA-AOMDV) is proposed in this paper. 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%.
