Novel Distributed Hash Table for Wireless Ad Hoc Networks
Jinling Wang · Jisuanji gongcheng · 2007
To build various applications in wireless ad hoc networks, an efficient data sharing mechanism is needed to facilitate cooperation and interaction among different nodes in the network. A novel data sharing solution is proposed for wireless ad hoc networks, namely Location-based DHT(LDHT), which combines the basic idea of distributed hash table(DHT) with the geographic routing technologies of ad hoc networks. Compared with traditional DHT schemes, LDHT is built upon the physical topology of the network rather than the logical overlay, so it eliminates the topology mismatching problem that exists in traditional DHT schemes and greatly improves the efficiency of data sharing in wireless ad hoc networks.
