Wireless SAW resonant sensors have been widely used in many applications, especially in harsh environment. The sensor is detected when the echo signal spectrum processed by Fourier transform exceeds a threshold. Because of complicated noise and electromagnetic interference in wireless channel, the threshold should be adaptive to interference in order to detect the sensor accurately. However, few researches...
Datacenters (DCs) are deployed in a large scale to support the ever increasing demand for data processing to support various applications. The energy consumption of DCs becomes a critical issue. Powering DCs with renewable energy can effectively reduce the brown energy consumption and thus alleviates the energy consumption problem. Owing to geographical deployments of DCs, the renewable energy generation...
Green communications has received much attention recently. For mobile networks, the base stations (BSs) account for more than 50% of the energy consumption of the networks. Therefore, reducing the power consumption of BSs is crucial to greening mobile networks. In this paper, we propose a novel energy spectrum trading (EST) scheme which enables the macro BSs to offload their mobile traffic to Internet...
Device-to-Device (D2D) communication as an underlaying cellular network empowers rich multimedia application, improves local communication, and enables local services, which would also bring out interference between cellular users and D2D terminals. In this paper, we study the challenges of the interference management in a hybrid network that D2D communication reuses uplink resource of cellular networks...
Device-to-Device (D2D) communication underlaying cellular networks will become an important technology in future networks such as IMT-Advanced to improve spectral efficiency. In order to enhance the overall system performance, the mutual interference between cellular and D2D communication caused by reusing the spectrum should be properly coordinated and channel allocation is considered as one of the...
