Interest-based lookup protocols for mobile ad hoc networks

In this paper, we propose two interest-based bandwidth-efficient lookup protocols, simple lookup protocol and advanced lookup protocol, for mobile environments. A peer willing to search files broadcasts a query message with keywords relevant to its interests to its neighbors in the transmission range, and only those neighbors also interested in the query forward. Simulation results show that our protocols have higher success rate and raise the scalability and bandwidth efficiency comparing to the previous work. Besides, our protocols can avoid selfish behaviors, since the behavior of forwarding queries benefits not only the source node but also the forwarding node.
