The rising popularity of wireless services resulting in spectrum shortage has motivated dynamic spectrum sharing to facilitate efficient usage of the underutilized spectrum. Wideband spectrum sensing is a critical functionality to enable dynamic spectrum access by enhancing the opportunities of exploring spectral holes, but entails a major implementation challenge in compact commodity radios that...
The electricity market of Singapore has been studied by many market regulators and scholars for its well-known maturity. This paper aims to provide an in-depth analysis of the market clearing model (MCM) of the wholesale market of Singapore, where the energy and ancillary services are settled simultaneously through a form of auction pricing. Both the bidding mechanism and the clearing process are...
Neighbor area network (NAN) is one of the most important segments of smart grid communications network (SGCN) since it is responsible for the information exchanges between the utility and a large number of smart meters (SMs) in order to enable various important smart grid (SG) applications. Greedy perimeter stateless routing (GPSR) and the routing protocol for low-power and lossy networks (RPL) have...
Cooperative spectrum sensing is employed in Cognitive Radio (CR) networks to reliably detect Primary User (PU) transmissions by fusing the sensed data of multiple Secondary Users (SUs). The local detection reliability of an individual SU is closely related to its channel condition. In this paper, we propose a scheme that uses SNR to evaluate the reliability of each individual SU's local decision....
