Abstract
MANET is a temporary wireless network composed of mobile nodes, in which there is no infrastructure. The mobile nodes can dynamically exchange data among themselves. Because of these characteristics, path connecting source nodes with destination may be very unstable and go down at any time, making communication over ad hoc networks difficult. Most of the routing protocols, despite of the belonging class (reactive, proactive, and hybrid), do not scale well when the number of nodes grows. Recently, some routing protocols have exploited the idea to decouple node identification from node’s location (Dynamic Addressing) by resorting to Distributed Hash Table (DHT) services. This paper provides the overview of the DHT technique and provides a survey of the various DHT based routing protocols in MANETs.
