In the context of reducing the dependence of transportation on fossil oil, a large number of alternative automobile technologies are considered, including a start-stop system, hybrid and plug-in hybrid vehicles, a full electric vehicle, and fuel cell. While some of these technologies have already been introduced into the market, others are still being developed. To meet future government regulations...
Searching for mobile data offloading solutions has been topical in recent years. In this paper, we present a collaborative WiFi-based mobile data offloading architecture - Metropolitan Advanced Delivery Network (MADNet), targeting at improving the energy efficiency for smartphones. According to our measurements,WiFi-based mobile data offloading for moving smartphones is challenging due to the limitation...
Wireless sensor networks have limited energy resource and therefore energy-efficient protocols are required to minimize the energy consumption. The virtual MIMO technique is considered as one of the new solutions to solve this problem. In this paper, in order to maximize the network lifetime, we propose a virtual MIMO transmission scheme coupled with multi-hop transmission. In our cross-layer design,...
Cooperative MIMO transmission technique is considered as one of the effective solutions to reduce the energy consumption in wireless sensor networks. However, the existing cooperative MIMO based protocols only focused on how to reduce the energy consumption, but for some applications such as audio/video surveillance sensor network, a large amount of gathered data (formulated as network utility function)...
