Congestion-Aware Multipath Routing in Ad Hoc Networks
Yuan Yongqiong, Zhang Jun, Feng, Liu · ASME Press eBooks · 2012
In an ad hoc network with flooding-based on-demand routing, many routing messages are propagated unnecessarily. Besides, the widely used minimum hop-count routing metric could not guarantee to find a network high-throughput path. For the above questions, we present a Congestion-aware Multipath Routing (CMR) algorithm in ad hoc networks. In the route discovery, by introducing parameters which is related with the node density of the network, we propose the distance-based flooding constraint broadcasting. It restricts flooding in a certain area according to the node density, but guarantees almost all nodes to receive the packet. Route selection and traffic distribution among multipath...
