Peer-to-peer (P2P) computing involves exchanging resources and files by computers connected through a network rather than a central server. In P2P, over mobile ad hoc networks (MANETs), the fundamental necessity is the linkage of the overlay participating peers (OPPs) for the efficient operation of the DHT-based P2P overlay protocol over MANETs. This necessity becomes more critical in a high mobility environment. Due to the high mobility of OPPs, the topology of the P2P overlay is altered continuously. Consequently, the efficiency of DHT-based P2P overlay protocol over MANETs greatly decreases due to the increased lookup latency, maintenance, computational, and control overheads. In the current research, a novel three-dimensional clustered overlay P2P protocol, i.e., 3DCOP, is suggested to cope with the identified issues. Simulation results depict that 3DCOP performs better in routing overhead, false-negative ratio, path-stretch ratio, and file discovery delay in the high mobility environment over MANETs.
