Performance evaluation of chord in mobile ad hoc networks [link]Paper  doi  abstract   bibtex   
Mobile peer-to-peer applications recently have received growing interest. However, it is often assumed that structured peer-to-peer overlays cannot efficiently operate in mobile ad hoc networks (MANETs). The prevailing opinion is that this is due to the protocols\textquoteright high overhead cost. In this paper, we show that this opinion is misguided.We present a thorough simulation study evaluating Chord in the well-known MANET simulator GloMoSim. We found the main issue of deploying Chord in a MANET not to be its overhead, but rather the protocol\textquoterights pessimistic timeout and failover strategy. This strategy enables fast lookup resolution in spite of highly dynamic node membership, which is a significant problem in the Internet context. However, with the inherently higher packet loss rate in a MANET, this failover strategy results in lookups being inconsistently forwarded even if node membership does not change.
