In mobile ad hoc networks, GOAFR+ (greedy other adaptive face routing plus) has a strong point that guarantees the packet delivery to the destination with low cost by combining greedy forwarding and face routing. In face routing mode, GOAFR+ uses the boundary circle to restrict a searching area. However, since the boundary circle is used without any location information of neighbors, it caused unnecessary...
Flooding in wireless ad hoc networks is one of the most fundamental operations to propagate control messages in entire network. The traditional flooding scheme generates excessive packet retransmissions, resource contention, and collisions since every node forwards the packet at least once. Recently, several flooding schemes have been proposed to avoid these problems; however, these unnecessary forwarding...
This paper proposes a novel multi-hop clustering scheme that aims to address the following concerns: effectiveness, stability, and reliability. Since cluster backbone tends to become more stable when cluster size is large, we focus on multi-hop clustering rather than one-hop clustering. Next, our paper introduces intra-connection degree as a new cluster selection metric. As a result, the reliability...
