Both Mobile Ad hoc Networks (MANETs) and Peer-to-Peer (P2P) networks are decentralized self-organizing networks with a dynamic topology, used to route queries in a distributed environment. However, whilst MANETs are composed of resource-constrained devices susceptible to faults, P2P networks are popular for their resilience and fault-tolerance. This makes P2P networks the ideal data sharing system for MANETs. This chapter focuses on the integration of these networks. More specifically, the authors evaluate routing strategies of both the network layer and the application layer. Their results indicate that the performance of the protocols depends greatly on the environment and point out the need for new approaches. © 2009, IGI Global. 94116Barrett, C.L., Eidenbenz, S.J., Kroc, L., Marathe, M., Smith, J.P., Parametric probabilistic sensor network routing (2003) Proceedings of the 2nd ACM International Conference On Wireless Sensor Networks and ApplicationsBorg, J., (2003) A Comparative Study of Ad Hoc & Peer to Peer Networks, , Unpublished master's thesis, University College London, UKBoukerche, A., Zarrad, A., Araújo, R., Smart gnutella overlay formation for collaborative virtual environments over mobile ad-hoc networks (2006) Proceedings of the IEEE International Symposium On Distributed Simulation and RealTime Applications (DS-RT)Broch, J., Maltz, D.A., Johnson, D.B., Hu, Y.-C., Jetcheva, J., A performance comparison of multi-hop wireless ad hoc network routing protocols (1998) Proceedings of the 4th Annual ACM/IEEE International Conference On Mobile Computing and NetworkingCano, J.-C., Manzoni, P., A performance comparison of energy consumption for mobile ad hoc network routing protocols (2000) Proceedings of the 8 th International Symposium On Modeling, Analysis and Simulation of Computer and Telecommunication Systems (MASCOTS)(2004) The CMU Monarch Projects On Wireless and Mobility Extension to Ns, , CMU Projectda Hora, D.N., Macedo, D.F., Nogueira, J.M.S., Pujolle, G., Optimizing peer-to-peer content discovery over wireless mobile ad hoc networks (2007) Proceedings of the 9 th IFIP/IEEE International Conference On Mobile and Wireless Communications Networks (MWCN)de Couto, D.S.J., Aguayo, D., Bicket, J., Morris, R., A high-throughput path metric for multi-hop wireless routing (2003) Proceedings of the 9th Annual International Conference On Mobile Computing and Networking (MOBICOM)Ding, G., Bhargava, B., Peer-to-peer file-sharing over mobile ad hoc networks (2004) Proceedings of the 2nd IEEE Annual Conference On Pervasive Computing and Communications WorkshopsFall, K., Varadhan, K., (2001) Network Simulator Notes and Documentation, , The VINT ProjectFranciscani, F.P., Vasconcelos, M.A., Couto, R.P., Loureiro, A.A.F., Reconfiguration algorithms for peer-to-peer over ad hoc networks (2005) Journal of Parallel and Distributed Computing, 65 (2), pp. 234-245Gaertner, G., Cahill, V., Understanding link quality in 802.11 mobile ad hoc networks (2004) IEEE Internet Computing, 8 (1), pp. 55-60Gkantsidis, C., Mihail, M., Saberi, A., Random walks in peer-to-peer networks (2004) Proceedings of the IEEE International Conference On Computer Communications (INFOCOM)Hu, Y.C., Das, S.M., Pucha, H., Exploiting the synergy between peer-to-peer and mobile ad hoc networks (2003) Proceedings of the 9th Workshop On Hot Topics In Operating SystemsJohnson, D.B., Maltz, D.A., Dynamic source routing in ad hoc wireless networks (2001) Ad Hoc Networking, , In C.
