This paper presents the architecture of a complete communications platform for sensor-based applications. It covers from the direct communication with the sensors themselves to the most remote application modules. It has been divided into three levels: BAN (Body Area Network), LAN (Local Area Network) and WAN (Wide Area Network), and it uses wireless communications at all levels of the architec...

With the development of intelligent mobile phones and the improvement of wireless communication infrastructure, mobile payment is gradually accepted by the public. However, since intelligent mobile phones are not trusted devices, mobile payment faces serious security problems. To address the problems, this paper designs a trusted mobile payment scheme based on body area networks. The scheme bui...

The implementation of network coding in energy-challenged sensor networks, such body area networks, requires consideration of the energy cost of coding and the benefits that coding can provide in reducing the number of transmissions for successful reception. In this talk, we consider three different aspects of implementing network coding in body area networks, from low-level construction of mod...
