A Survey of Technical Requirements and Consumer Application Standards for IP-based Smart Grid AMI Network

Abstract The smart grid is a new advanced electrical network promoted by the government to address environmental sustainability, energy generation, distribution and consumption efficiency issues. As one of the enabling technologies, Advanced Metering Infrastructure refers to systems which measure, collect and analyze energy usage, and interact with advanced devices such as smart meters through various [...]

Powering Wireless Sensor Networks Nodes in Northern Europe Using Solar Cell Panel for Energy Harvesting

Abstract Harvesting energy from the sun is the most effective technology for outdoor applications. A combination of solar cells and chargeable batteries gives nodes with potentially eternal lifetime. The sun irradiance varies through the day and through the seasons, and is strongly dependent on the latitude. This must be taken into account if a wireless [...]

Fundamentals of Energy-Constrained Sensor Network Systems

Abstract This article is an overview of energy-constrained sensor networks, focusing on energy-conserving communications and signal processing strategies. We assume battery driven nodes, employing robust communications, with little or no fixed infrastructure. Our discussion includes architectures, communications connectivity, capacity and scalability, mobility, network localization and synchronization, distributed signal processing, and cross-layer issues. Because energy is [...]

Energy Harvesting Sensor Nodes: Survey and Implications

Abstract Sensor networks with battery-powered nodes can seldom simultaneously meet the design goals of lifetime, cost, sensing reliability and sensing and transmission coverage. Energy-harvesting, converting ambient energy to electrical energy, has emerged as an alternative to power sensor nodes. By exploiting recharge opportunities and tuning performance parameters based on current and expected energy levels, energy [...]
