A Resource Discovery Algorithm Based on Mobile Ad hoc Network and Its Implementation

This paper proposes the mobile resource discovery algorithm called MRDA, which focus on the communication of Mobile Ad-hoc Network (MANET) nodes in a peer-to-peer manner. It utilizes distributed hash tables (DHTs) to efficiently cache the resource information. Meanwhile, we design the simple datagram structure and use dynamic transmission interval of advertising datagram, which can effectively reduce the mobile phone´s memory occupancy and decrease the network transmission cost. Finally, we design and implement prototype program of communication between the mobile terminal nodes in MANET environment, which can illustrate the efficiency of MRDA.
