With the rapid growth of the Internet, deploying energy-efficient networking technology is an urgent matter. In particular, wireless LAN (WLAN), which is widely used due to its ease of deployment and low cost of installation, is also required to be energy efficient. For this purpose, R & D activities for Radio-On-Demand-Networks (ROD) have been proposed. In ROD networks, access points (APs) have...
Multihop wireless networks (MWNs) can dynamically extend the coverage area of wireless local area networks (LANs). Communication performance of MWNs that use a single channel decreases due to interference between nodes occurring when frames are being relayed. In this paper, we proposed an autonomous dynamic transmission scheduling scheme for MWNs that is based on the behavior of neighbor nodes. In...
Mathematical analysis reveals that high frequency signal components are the main issues that make MRF algorithm essential. Moreover, the aliasing problem of subsampling algorithm also comes from high frequency signal components. So based on these mathematical investigations, two fast VBSME algorithms are proposed in this paper, namely roberts cross edge detector based subsampling method and motion...
