The concept of Participatory Sensing is centered on individuals that collect data using their smart phones (or other dedicated devices) to track the evolution of their work/living places. The main objective is to use the gathered data in order to enhance the offered quality of life. To maximize people involvement in this process we propose a ferry based architecture to leverage the contributors from...
Mobile WiFi hotspots have become increasingly popular as a new innovative wireless Internet access technology. Although it has received little attention, adaptive, dynamic (re)assignment of channels in a mobile hotspot router — typically, a smartphone or a laptop or a tablet equipped with heterogeneous network interfaces like 3G/4G, WiFi, Bluetooth or ZigBee — is key to mobile hotspot performance...
Transmission power control (TPC) has been extensively used not only to save energy, but also to improve the network throughput in wireless ad hoc networks. Among the existing throughput-oriented TPC protocols, many can achieve significant throughput improvement but have to use multiple channels and/or multiple transceivers, and others just require a single channel and a single transceiver but can...
Energy consumption is of utmost importance in ad hoc wireless networks where battery-operated nodes have limited power resources. Energy consumption is also important in meshed WLAN networks such as emerging home entertainment networks and meshed WiMax metropolitan area networks. So far, it has been advocated that nodes have to operate at the lowest possible power level that keeps the network connected...
