Layered multicast protocol (LMP) is designed to support simultaneous and real-time multimedia content distribution to large number of disparate receivers across the heterogeneous Internet. However, the current layered multicast protocols (LMPs) use the techniques that do not correctly model TCP behaviour, which results in the protocols can't fairly compete with TCP. TCP-friendly layered multicast...
TCP-friendly rate control(TFRC) is an equation-based congestion control mechanism that competes fairly with TCP but has a much lower throughput variation, which makes it a better choice for streaming over the Internet. It is known that in a mobile network environment, after a handover TFRC can overshoot or under utilize the new link if the conditions there differ from those of the old link. There...
One of the most significant challenges that confront end-to-end multicast congestion control is providing a scalable solution that addresses the heterogeneity of the receivers. There exist two categories of rate based multicast congestion control approaches. The first category is a single rate where the source adjusts the sending rate dynamically according to the slowest receiver within the session...
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,...
This paper presents a distributed fermat-point range estimation strategy, which is important in the moving sensor localization applications. The fermat-point is defined as a point which minimizes the sum of distances from three sensors inside a triangle. This point is indeed at the trianglepsilas center of gravity. We solve the problems of large errors and poor performance in the bounding box algorithm...
