An ad hoc network is a collection of mobile computing devices that can communicate over a shared wireless channel. Unlike the cellular network or WLAN, these nodes can communicate in single or multi-hop fashion without the aid of base station or access point.
In addition to the lack of infrastructure in an ad hoc network, the nature of the wireless channel and the dynamic topology pose a number of challenging problems across the OSI layers. For instance, a multi-hop routing protocol has to be robust enough to establish and maintain routes in the frequently changing network. Moreover, power consumption becomes a critical issue since the networks rely on forwarding data packets. The protocols designed for the ad hoc network have to provide reliable and uninterruptible communication in the dynamic propagation conditions without prior planning.
In this seminar, we will look into the problems and the state-of-the-art of ad hoc network technology. Students attending the seminar are expected to read and present a selection of recently published research papers, and actively take part in discussions.
