Cooperation in ad-hoc networks: Wireless multihop networks from theory to practice

Abstract

In this chapter we are outlining the major challenges encountered when one is trying to deploy realistic ad hoc networks. We are also emphasizing that the current trend towards less mobile mesh networks and sensor networks are actually most probably enabling the emergence of ad hoc type of networks for the civilian markets. Our main focus is to give enough starting points for interested reader to read more specific literature on the existing research in this fast moving field. One of the main conclusions of the chapter is that providing cooperative ad hoc networks requires much more than deploying ad hoc routing capability into network. Especially if one is limited to use IEEE 802.11 technologies, one has to be very careful with the performance limitations. Apart of advocating the less-mobile mesh networks, we point out that the recent suggestion to use "multiradio" approach is a very sensible one. We also speculate on more advanced research possibilities, namely we point out that cognitive radio and networking principles especially, if combined with efficient topology awareness might be an effective way to ensure optimal and cooperative ad hoc networks in the future. © 2006 Springer.
