As the wireless network scales up in size and complexity, the need to study the scalability and behaviors of these networks and their protocols becomes essential. Opportunistic routing utilizes broadcast nature of wireless network, and significantly increases the unicast throughput. However, all of the current opportunistic routing protocols have to rely on the whole topology information. This indeed...
A practical scenario to realize Ad hoc network based on the Linux operation system is proposed in this paper. A practical test network composed of several nodes is built and DSR (Dynamic Source Routing) protocol is selected to run on the test network. Meanwhile, in order to obtain better support for real time multimedia services, an improved DSR protocol considering delay demand is also testified...
Cluster-based routing protocol is currently a hot research in wireless sensor network. In this paper, we propose an improved method RECHS(Redundant and Energy-efficient Clusterhead Selection) for LEACH protocol to balance network load and to extend the network life. In order to selecting reasonable clusterheads, our scheme first selects initial clusterheads and initial redundant clusterheads. By comparing...
