Communication issues in large scale wireless ad hoc networks

Research output: Chapter in Book/Report/Conference proceedingChapter (peer-reviewed)peer-review

Ad-hoc networks are networks that are formed automatically without any pre-existing infrastructure. These networks may consist of various types of mobile devices – such as PDAs, laptops, cell phones and other mobile computing devices. Each node in a wireless ad hoc network performs computational tasks as well as communication routing. Without the existence of dedicated routing devices, the nodes relay traffic to each other to extend their communication range. This paper gives an overview on the current technologies – intelligent agent systems – and their implications to solve common problems in ad hoc networks. We will also introduce our current research directions, and provide a promising analysis to achieve efficient transmissions in a large-scale ad hoc network using multiple channels, an option, which is already in the MAC layer of IEEE 802.11. We will show also that in noisy environments latency reduction in multi-hops is significant to single hop networks even for greater number of relay nodes. The approach described in this paper could be use to develop efficient large-scale ad hoc networks.
