Service Demand Discovery Mechanism for Mobile Social Networks

Abstract

In the last few years, the service demand for wireless data over mobile networks has continually been soaring at a rapid pace. Thereinto, in Mobile Social Networks (MSNs), users can discover adjacent users for establishing temporary local connection and thus sharing already downloaded contents with each other to offload the service demand. Due to the partitioned topology, intermittent connection and social feature in such a network, the service demand discovery is challenging. In particular, the service demand discovery is exploited to identify the best relay user through the service registration, service selection and service activation. In order to maximize the utilization of limited network resources, a hybrid service demand discovery architecture, such as a Virtual Dictionary User (VDU) is proposed in this paper. Based on the historical data of movement, users can discover their relationships with others. Subsequently, according to the users activity, VDU is selected to facilitate the service registration procedure. Further, the service information outside of a home community can be obtained through the Global Active User (GAU) to support the service selection. To provide the Quality of Service (QoS), the Service Providing User (SPU) is chosen among multiple candidates. Numerical results show that, when compared with other classical service algorithms, the proposed scheme can improve the successful service demand discovery ratio by 25% under reduced overheads.

Exploration of Learning Service Discovery Algorithm based on Ontology

“…Moreover, the Web service discovery mechanism based on UDDI only provides a simple keyword-based search method, and lacks support for semantic reasoning. Wu et al (2016) studied the concept of user satisfaction, and proposed a e-Learning service discovery algorithm based on user satisfaction [1]. Mohammadi (2015) profoundly studied the collaborative problem with computer as a tool.…”

Collaborative Web Service Discovery and Recommendation Based on Social Link

“…They used the former to help users select the necessary services, and adopted the latter to permit extending these services with new services or maintaining the operation continuity in case of failure. To maximize the utilization of limited network resources, a hybrid service-demand discovery architecture for mobile social networks was introduced in [5], in which users can discover their relationships with others based on the historical data of movement. In order to address the problems of the isolation of services and the lack of social relationships in Web service discovery, Chen et al presented a global social service network connecting the isolated service islands to enhance the services' sociability on a global scale in [6].…”

User Access Management Based on Network Pricing for Social Network Applications

“…Many aspects of social networks have been studied [ 1 , 2 , 3 ]. To guarantee quality of service (QoS) for users, a considerable amount of resources is required.…”
