Typical real-time routing data dissemination schemes employ 1-hop transmission speed based on the 1-hop lookahead manner that proactively obtains information of 1-hop neighbor nodes and selects one that satisfies a desired delivery speed as next hop. To improve performance of 1-hop lookahead based real-time routing protocols, THVR (Two-Hop Velocity-based Routing) is proposed. THVR reduces deadline...
Most existing geographic routing protocols on sensor networks concentrates on finding ways to guarantee data forwarding from the source to the destination, and not many protocols have been done on collecting and aggregating data of sources in a local and adjacent region. However, data generated from the sources in the local and adjacent region are often redundant and highly correlated. Accordingly,...
Tree topology information gathering protocols has been proposed in order that sinks can efficiently collect continuous data. In other words, sensor network initially constructs connection structure from sources to sinks. After that, continuous data are delivered to sinks through the connection structure. These protocols, although, could not be applied to the model of mobile sinks because the connection...
