Mobile ad-hoc networks (MANETs) are autonomous, self-configuring and dynamic networks that operate without the support of any fixed infrastructure. Such networks are excellent candidates for military logistics which requires identification of location of sensitive frights and other communication need. Ad hoc routing protocol supports nodes mobility with multi-hop routing overwhelming the limitations of radio coverage in remote locations. Most of the present routing protocols are not designed to adapt congestion which is the dominant reason for packet loss, longer delay and jitter. In this paper, the original DSR protocol was modified to monitor the occurrence of congestion by using multiple resource utilisation thresholds as QoS attributes and trigger multi-path-routing during the periods of congestion to improve QoS. This paper also deals with the effects of mobility on the modified routing protocol. The NS-2 simulation results showed that a significant improvement in performance of modified DSR was achieved and decreases the network congestion with the use of multi-path routing.
