X Abstract

With most routing protocols for ad hoc networks, shorter paths are generally considered more desirable, making some areas of network more prone to congestion and decreasing overall network throughput. We examine the use of congestion information to avoid these network hotspots. By locally monitoring the network interface transmission queue length and MAC layer behavior at each node, a node can establish an approximation of the degree to which the wireless medium around it is busy; this measurement reflects not only the behavior of the node itself, but also the behavior of other nearby nodes sharing the wireless medium. We suggest a number of uses of such congestion information in an ad hoc network, in the network, transport, and higher layers, and we evaluate a set of such uses through simulation. Our results based on modifications to the dynamic source routing protocol (DSR) and TCP demonstrate substantial performance improvement in terms of scalability, packet delivery, overhead, and fairness resulting from this use of congestion information.

CiteULike organises scholarly (or academic) papers or literature and provides bibliographic (which means it makes bibliographies) for universities and higher education establishments. It helps undergraduates and postgraduates. People studying for PhDs or in postdoctoral (postdoc) positions. The service is similar in scope to EndNote or RefWorks or any other reference manager like BibTeX, but it is a social bookmarking service for scientists and humanities researchers.
