The wireless data collected in mobile environments provides tremendous opportunities to build new applications in various domains such as Vehicular Ad Hoc Networks and mobile social networks. One of the biggest challenges is how to store these data. Storing the data decentralized in wireless devices is an attractive approach because of its major advantages over centralized ones. In this work, to facilitate...
Tang and Wu proposed an efficient mobile authentication scheme for wireless networks, and claimed the scheme can effectively defend all known attacks to mobile networks including the denial-of-service attack. This article shows an existential replication attack on the scheme and, as a result, an attacker can obtain the communication key between a mobile user and the accessed VLR. Fortunately, we improve...
Multicasting has not been widely adopted until now, due to lack of receiver or end user (EU) access control. We have developed the Internet group management protocol with access control (IGMP-AC), an extended version of IGMPv3, which provides EU access control by incorporating the AAA framework into the existing multicast service model. Furthermore, IGMP-AC works as an extensible authentication protocol...
We study access games within a large population of mobiles that interfere with each other through many local interactions. Each local interaction involves a random number of mobiles. The games are not necessarily reciprocal as the set of mobiles causing interference to a given mobile may differ from the set of those suffering from its interference. We model and study this using the theory of evolutionary...
