Different physical data communication technologies for the smart grid will empower the legacy power grid with the capability to support two-way energy and information flow. The smart grid will rely on several existing and future wired and wireless communication technologies (e.g., power line communication, cellular network, internet protocol networks, ZigBee, Wi-Fi, Worldwide Interoperability for Microwave Access, etc.). Also, advanced techniques for accessing the network and routing the information to the different nodes of the network will be required. In this chapter, we discuss smart-grid communication network and divide it into three tiers, i.e., home area network, neighborhood area network, and wide-area network. We present smart-grid communication technologies, standards, and protocols for the physical layer operations. We next discuss the medium access control (MAC) and network layer protocols of the smart-grid communication technologies. In the end, we present a case study for the implementation and performance evaluation of various smart-grid algorithms and communication infrastructure.

The proposed codes can achieve rate one and full diversity with lower complexity maximum likelihood detection. The design takes into consideration the signal power fluctuation and minimizes the potential peak-to-average ratio (PAPR) in the transmitted signals. The application to Single Carrier Frequency Division Multiple Access (SC-FDMA) has been investigated further. A transmission scheme is proposed to preserve the good PAPR property of SC-FDMA. In addition, linear and iterative decoding algorithms are proposed to simplify the receiver complexity. Simulations have been conducted to demonstrate the superior performance.

Forward error correction (FEC) coding is commonly adopted for data protection in implementing loss-resilient video transmission systems. However, the burst packet losses over the Internet frequently degrade FEC performance and induce video quality deteriorations. To address the challenging problem, we propose a novel transmission scheme dubbed trading delay for distortion (TELFORD) that includes three components: 1) adaptive multidestination status estimation; 2) delay-constrained transmission rate assignment; and 3) differentiated FEC packet spreading. We analytically formulate and solve the problem of FEC packet allocation and scheduling to minimize the end-to-end video distortion. The proposed TELFORD is able to cope with multiple-destination scheduling separately. We conduct performance evaluation through semiphysical emulations in Exata using real-time H.264 video streaming. Experimental results show that TELFORD outperforms existing error control transmission schemes in improving the video peak signal-to-noise ratio and mitigating packet transmission impairments.
