Abstract?This paper focuses on the problem of implementing a distributed hash table (DHT) in wireless ad hoc networks.Scarceness of resources and node mobility turn routing into a challenging problem and therefore, we claim thatbuilding a DHT as an overlay network (like in wired environments) is not the best option. Hence, we present aproof-of-concept DHT, called Cell Hash Routing (CHR), designed from scratch to cope with problems like limitedavailable energy, communication range or node mobility. CHR overcomes these problems, by using position information to organize a DHT of clusters instead of individual nodes. By using position-based routing on top ofthese clusters, CHR is very efficient. Furthermore, its localized routing and its load sharing schemes, make CHRvery scalable in respect to network size and density. For these reasons, we believe that CHR is a simple and yetpowerful adaptation of the DHT concept for wireless ad hoc environments.
