Abstract
This paper proposes an on demand source routing protocol with multiple disjoint paths for ad hoc networks to support soft bandwidth constrained QoS requirement, which is termed as the Active Multipath QoS Routing (AMQR) protocol. A distributed route discovery algorithm is proposed to find multiple disjoint paths with associated path stability and network resource information. In addition, an actively dynamic route maintenance algorithm based on periodic state update combined with gratuitous QoS_ACK replies is introduced to refresh network topology and resource information, which helps the source dynamically adjust the traffic load on the desired route for data dispersion. Simulation results compared with DSR show that AMQR provides excellent end-to-end QoS.
