With rapid advances in multimedia and wireless network technologies, it is now feasible to provide live video streaming over wireless networks. However, since bandwidth is a scarce resource in wireless networks, it is important to design an adaptive bandwidth allocation scheme for video streams to make efficient use of wireless bandwidth. In this paper, we(More)
Sensors redeployment is a straightforward way to increase the lifetime of a Wireless Sensor Network (WSN) by deploying additional sensor devices in the sensing region. This paper considers the problem of finding positions to deploy sensors so that the network lifetime will be the most prolonged when a fixed total quantity of energy of sensor devices is(More)
Wireless mesh networks (WMNs) are expected to play an important role in the next-generation Internet because of its several advantages, such as self-organization, high capacity, low deployment cost and low maintenance cost. In this paper, we discuss how to provide robust home-to-home on-demand streaming on the basis of WMNs. A key challenge for such a(More)
