Mobile social networks (MSNs) are a kind of delay tolerant network that consists of lots of mobile nodes with social characteristics. Recently, many social-aware algorithms have been proposed to address routing problems in MSNs. However, it also brings more security and privacy concerns. In this paper, we discuss a specific type of Sybil attack in MSNs, which few researches has been focused on. We...
We tackle the network selection problem in operator-initiated mobile data offloading by considering both the predictive and non-predictive cases. For the non-predictive case, we use the Lyapunov optimization technique to design the Delay-aware Network Selection Algorithm (DNSA), which yields an operation cost within O (1/V) bound of the minimum value, for any V > 0. For the predictive case, we...
This paper proposes a novel multicast mobility solution aimed for mobile video, empowered by a cross-layer approach leveraging on the capabilities of Multicast Context Transfer and IEEE 802.21 Media-Independent Handover. The proposed solution was implemented and deployed in a real testbed, with results showing the significantly reduced latency for vertical handovers.
Self-certifying names provide the property that any entity in a distributed system can verify the binding between a corresponding public key and the self-certifying name without relying on a trusted third party. However, self-certifying names lack a binding with a corresponding real-world identity. In this paper, we present a concrete mechanism for using a Web-of-Trust in conjunction with self-certifying...
The content routing protocols for MANETs proposed to date require the flooding of content requests or link-state advertisements. The Adaptive Publish-subscribe Distance Vector (APDV) protocol is presented as an alternative. APDV combines routing to well-known directories using distance-vector signaling with publish-subscribe mechanisms to discover content. Named data objects (NDO) are published with...
Information-centric networks have recently been drawing increasing attention in academia as well as in industry. Information and content retrieval is a critical service for mobile ad-hoc networks. It relies on other resources and tools, such as internal storage, content searching and sharing, delay-tolerant delivery, etc. Previous studies have shown that social networking can assist delay-tolerant...
The digitization of social networks has enabled the passive collection of large scale data, which in turn have fostered social studies that have been traditionally dependent on small scale, interview-based data. During the last years, a new class of digital social networks has emerged, namely, location-based social networks (LBSNs). The main interaction between users of an LBSN is location sharing,...
