As malware attacks become more frequently in mobile networks, deploying an efficient defense system to protect against infection and to help the infected nodes to recover is important to prevent serious spreading and outbreaks. The technical challenges are that mobile devices are heterogeneous in terms of operating systems, the malware infects the targeted system in any opportunistic fashion via local...
Vehicular Delay Tolerant Networks (VDTN) are used to distribute a large amount of mobile data by high-capacity device-to-device communication. Given a number of available vehicles in VDTN, the current vehicular data sharing models always utilize all of them to achieve the best effect, failing to balance the performance gained and cost of employing them. Taking the cost into account, we study the problem...
Groups of people with mobile phones using short range connections like WiFi and Bluetooth to propagate messages can be modeled as, with regard to regular absence of end-to-end connection, Delay Tolerant Networks (DTNs). The study of message transmission speed in such kind of networks has attracted increasing attention in recent years. In this paper, we present a realistic framework to model the message...

With the development of mobile networks, terminals' locations become increasingly valuable for both the whole system performance and terminals' applications or services. As knowing the knowledge of terminals' location information in advance would provide extern preparation time to accelerate response to terminals' requirements, location prediction plays a quite important role. Since most of the mobile...
Proxy mobile IPv6 (PMIPv6), a network-based IP mobility solution, is a promising approach for mobility management in all-IP wireless networks. How to enhance its handoff-related performance, such as handoff delay and signaling cost, is an important issue. Current solutions rely on approaches such as fast handoff, routing optimization and paging extension. However, the case of many correlated mobile...
Proxy mobile IPv6 (PMIPv6) is being actively standardized by IETF, and its salient features, such as supporting unmodified mobile node (MN), expedite the real deployment of IP mobility management. However, current research and development mainly focus on its unicast mechanism. In this paper, we propose two multicast listener mobility mechanisms for PMIPv6, named LMA-MLM and MAG-MLM, by drawing a lesson...
As the inherent defects of the client-server model, the dependency on the server profoundly confines the system's scalability and seriously clashes the reliability and security of the system. This situation grows into more serious when numerous peers involved in a multiparty IM session. To remedy these deficiencies, this research probes the prospects of using P2P networking paradigm in the multiparty...
