Multihop connectivity is the ability of the multiple-hops-away nodes—nodes which are not directly connected—to communicate with each other. Since wireless ad hoc networks are infrastructure-less, the participating nodes themselves are supposed to establish the service of multihop connectivity by forwarding the messages on behalf of each other. Routing and Relaying are the two approaches to provide multihop connectivity in wireless ad hoc networks.
