Wireless Sensor Networks (WSNs) are designed for supporting applications in long-term deployments. However, the researchers have recently explored many new WSN systems. To address the issue of noise presence in real time scenarios, a noise-measuring system based on WSN is presented in this paper. It can be used to collect data at unattended measuring-points, and transmit it to the data center. After...
Wireless Power Transmission (WPT) is a technique to charge electrical devices (EDs) remotely. In WPT, power source (Smart Wireless Charger) transmits power wirelessly, using air as the medium, to EDs. In this paper, we present an Auction mechanism to obtain the energy trading between Smart Wireless Chargers (SWCs) and EDs. In our proposed Double-Auction based charging trade mechanism, our priorities...
Vehicle speed monitoring and management of the associated data in an intelligent and efficient way is an important issue in modern transportation system in order to reduce road accidents. The aim of this work is to develop an automatic wireless system for monitoring vehicle speed on the road, identify a speeding vehicle and imposing penalty for the speeding offenders. In this work, a prototype system...
Over the recent years, one of the most important problems in wireless sensor networks (WSNs) is to develope an energy-efficient and reliable routing protocol and provide network robustness. To achieve these objectives, we propose a new architecture for data dissemination called Two Tier Cluster Based Routing Protocol (TTCRP) for reliable data delivery in WSNs. TTCRP uses resource rich cluster heads...
Wireless sensor and actor network (WSAN) is formed by the collaboration of micro-sensor and actor node. Whenever there is any special event i.e., fire, earth quake, flood or enemy attack in the network, sensor nodes have responsibility to sense it and send information towards an actor. The actor node is responsible to take prompt decision and react accordingly. Sensor nodes have limited resources...
Owing to the growing demand for low-cost 'networkable' sensors in conjunction with recent developments of micro-electro mechanical system (MEMS) and radio frequency (RF) technology, new sensors come with advanced functionalities for processing and communication. Since these nodes are normally very small and powered with irreplaceable batteries, efficient use of energy is paramount and one of the most...
