Computer networks have long suffered from congestion. Congestion occurs when an increase in the offered load results in a decrease in the effective throughput of the network. The basic cause is that the short term packet arrival rate at some gateway exceeds its service rate. Existing congestion control schemes treat congestion as an individual problem and propose ad hoc solution that are dissat...

An ad hoc network is a distributed and self-organized network, where wireless terminals exchange network information with neighbor terminals and construct a multi-hop network. The topology of such a network changes frequently because of the unsettled wireless environment and/or terminal mobility. Consequently, appropriate route maintenance is necessary. In this thesis, we first focus on a comme...

Ad hoc wireless networking is currently a hot research area, especially because there is an increasing need for connectivity “anywhere” and, in particular, “anyhow.” While traditional networks have fixed nodes with wired connections (either optical fibers or copper lines), ad hoc wireless networks can be described as multi-hop wireless networks with mobile nodes. However, the mobility condition...

Mobile ad hoc networks have gained a great deal of attention because of its significant advantages brought about by multi-hop, infrastructure-less transmission. This paper addresses the problem of delivering data packets for highly dynamic mobile ad hoc networks in a reliable and timely manner. The Most of existing ad hoc routing protocols are susceptible to node mobility, mainly for large-scal...
