NextContact: Neighbor Discovery Mechanism for Opportunistic Networks
Prashant Kumar, Naveen Chauhan, Narottam Chand · International Journal of Grid and Distributed Computing · 2017
Node discovery plays a vital role in opportunistic networks in order to efficient use of available resources as these networks suffered from intermittent connectivity.In opportunistic networks encounters are uncertain and it is difficult to determine the occurrence of next encounter.To make most out of the short contact duration it is essential that opportunistic networks must have an efficient node discovery procedure.In this article, we present a node discovery scheme called "NextContact".NextContact is based on the node movement.We investigate a formula to derive the probing interval to probe for the next encounter.Further we conduct simulation to validate the correctness of our proposed scheme.
