Alternate path routing (APR) can provide load balancing and route failure protection by distributing traffic among a set of diverse paths. These benefits make APR appear to be an ideal candidate for the bandwidth limited and mobile ad-hoc networks. However, we find that APR's potential is not fully realized in ad-hoc networks because of route coupling(More)
This research used a custom event-driven network simulator to evaluate Alternate Path Routing’s (APR’s) behavior in Mobile Ad Hoc Networks (MANETs). In particular, it investigated how much route-diversity is inherent in typical ad-hoc networks, and the ability of a globally reactive routing-protocol (such as the Zone Routing Protocol) to capture and utilize(More)
This paper describes an experimental implementation of a QoS-aware hybrid routing protocol that uses a flexible mix of proactive and reactive routing techniques within Mobile Ad hoc Networks (MANETs). After a brief review of the benefits and applications of proactive, reactive (ondemand) and hybrid routing, the architectural details and protocol operation(More)
Ad-hoc networks are network architectures that can be rapidly (ideally immediately) deployed and that do not need to rely on pre-existing in.astructure. The salient feature of this breed of networks is that they can operate in dl~erent and differing propagation and network operational conditions, which cannot be predicted during the network design stage.
