Cooperative relaying has played an important role in the rapid evolution of wireless communications. The cooperative performance strongly depends on the selected relays. In this paper, an improved Least Maximum Pathloss (LMP) method is analyzed for the relay node selection. Both the direct transmission as well as the traditional LMP and the improved LMP under the condition of cooperative amplify-and-forward...
In peer-to-peer (P2P) networks, multiple sources multimedia transmission is one of the key technology in peer-to-peer (P2P) networks because of simultaneous multimedia file sharing. However, allowing all available sources to transmit to the destination node may result in serious network congestion. Thus the selection of multiple sources is one of the key issues in the design of multi-source multimedia...
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...
