Gathering data from sensors, mobile sink has been adopted in wireless sensor networks (WSN) and wireless sensor and actor network(WSAN) to achieve higher efficiency. With the help of mobile sink, sensors could attain a much longer lifetime than the past. However, mobile sink introduces new challenges such as large data gathering latency to WSN/WSAN. A lot of research efforts have been devoted to reduce...
While the use of mobile web services has shown a considerable increase, Mobile 2.0, integrating the mobile network and the Internet, is proposed to provide rich forms of composite services for mobile users. In this paper, we propose a framework for Mobile 2.0 to reduce the negative influence of the mobile constraints and make it easier to access the Internet and acquire web services for mobile devices...
In order to enable mobile network to provide anonymity services, ensure the confidentiality of the user's identity, whereabouts and other information, we raised an anonymous authentication scheme. The scheme solves the problem of user's anonymity not only in roaming network, but also in adscription network. The scheme bases on binary tree theory and the knowledge proof, and combines divisible e-cash...
In order to provide anonymity services for mobile network users, ensure the confidentiality of the user's identity, we raised an anonymous authentication scheme without trusted third party. The scheme not only solves the problem of user's anonymity in the whole network, but also can open the message to track users when necessary, and achieve controllable anonymity. The scheme is implemented by difficult...
