Location based multihop communication in mobile ad hoc networks

Abstract

In line with traditional communication systems, more and more attention is given to autonomous, self-organized networks with no central infrastructure, based on peer-to-peer communication, like mobile ad hoc networks. Designing multihop broadcast protocols for ad hoc networks is a complex problem as the task of these protocols is to disseminate messages in a network effectively while avoiding unnecessary use of resources. To solve this problem, this paper presents three adaptive multihop broadcast protocols, which assign broadcasting probabilities to the mobile nodes, determining them from the network parameters (like the degrees of the nodes, distance of the nodes from each other). The presented novel 3-phase handshake gossiping protocols generate significantly less duplicates while giving a faster coverage of the nodes than the other examined protocols.
