In this paper, we address the problem of allocating channels to wireless users in the multiuser-multichannel dynamic spectrum access (DSA) scenario. To solve this problem, we introduce a special form of multi-armed bandit (MAB), named exploration bandit, into DSA for the first time. Two distributed algorithms are proposed to maximize the channel rewards (e.g., transmission rates) of the users. Meanwhile,...
Cyber-Physical Systems (CPS), such as networked control systems, are increasingly deployed over wireless networks. Given the sensitivity of control systems to networking conditions such as packet drops, delays and jitters, it is important to verify and evaluate the control system properties under realistic wireless networking deployment scenarios. However, current research is often based on simplistic...
The use of wireless sensor networks as a means for providing remote healthcare provides a unique opportunity to reduce the healthcare cost through more efficient use of clinical resources and earlier detection of medical conditions. Despite the initial promising results, there remain significant obstacles to apply this technology to the practical medical care context. In this paper, we investigate...
Recent advances in wireless sensor technology facilitate the development of remote healthcare systems, which can significantly reduce the healthcare cost. Despite the initial promising results, there remain many obstacles to apply this technology to the practical medical care context. One of the critical issues is to assure the timely and robust delivery of the life-critical medical data in the resource-constrained...
Video sensor network is evolving from an isolated system to an integral component of the global information infrastructure. In this paper, we argue that when video sensor network becomes a public information source on the Internet, DRM (digital rights management) must be enforced, due to the sensitivity and the privacy natures of sensor content. Moreover, existing DRM solutions do not suffice because...
