User-specific network controlled device-to-device (D2D) communication is a promising method to improve the system performance of the future cellular networks. It is a challenging task to realise the optimal link adaptation for D2D reliable multicast because of the nature of wireless radio channels. In this study, network coding is employed to enhance D2D multicast by introducing the characteristic...
Our research team at the University of Nebraska's Advanced Telecommunications Engineering Lab (TEL) is working closely with the North American freight railroad industry to leverage wireless sensor networks (WSN) onboard railcars for advanced monitoring and alerting. Because freight train WSNs exhibit a linear chain-like topology of significant length, the existing IEEE 802.15.4 communication protocol,...
In this paper, we address the problem of maximizing sensor networks lifetime as well as maintain sufficient sensing coverage. The problem of computing redundant sensing areas among neighboring heterogeneous sensors is analyzed. We present a mathematical model to compute the redundancy degree of each sensor without the knowledge of location information for heterogeneous wireless sensor networks. Based...
