In opportunistic routing the next relay is selected at each hop of each packet depending on the local pattern of simultaneous transmitters. The protocol considered in this paper assumes that at each hop, the optimal relay is chosen in a greedy way such that the packet receiver minimizes the remaining distance to the destination. The selection between potential relays is done using a logarithmic scale...
The underwater target localization problem is one important application for underwater acoustic sensor networks. This paper, based on "underwater acoustic transmission theory", solves the target localization problem. The proposed algorithm firstly studies the principle of underwater acoustics and applies it to set up the model of underwater signal energy transmission. According to the model,...
