Analysis of GHT in mobile Ad hoc networks

Abstract

Distributed Hash Table (DHT) is a technology widely used in today's network applications. With the rapid growth of mobile ad hoc network (MANET), a interface similar to DHT will be used in MANET. However the traditional approaches to construct DHT may not work in MANET due the routing problem in MANET. S. Ratnasamy etc. recently put forward the Geographic Hash Table (GHT) with the same interface as DHT in sensor networks. We wonder this approach can be used in MANET. In this paper, we provide some analyses and evaluations of GHT by means of simulation with ns-2. We present quantitative results with the cost of data dissemination and data query, the success rate, in various mobile scenarios and with different node density. © Springer-Verlag Berlin Heidelberg 2005.
