Using text information contained in web documents, the structure of smartphone application services is quantitatively and systematically analysed through two steps. First, representative services are identified and characterised to find distinctive features of current smartphone application services in the App Store by using text-mining and the set-covering algorithm. Second, based on representative services, three visual forms grid, tree, and network are illustrated to illuminate the structure of smartphone application services.

This research provides a social network-based group decision model which accounts for collective intelligence. This work considers peers from a user's social network as experts in the group decision-making process and each peer has its own internet agent. The purpose is to conduct a virtual group decision-making process over the internet at anytime. Each agent can reason by enabling the case-based reasoning approach and discuss by the proposed decision model. The proposed approach attempts to improve efficiency and effectiveness for a quality decision, which is extremely critical and crucial. This work also designed a system which: empowers collective intelligence from a social network; enhances trustworthy group decisions of the social network; ensures heterogeneity of selected experts; diminishes the domination of certain experts.

The findings indicate that self-control is the most significant predictor of mobile phone addiction. Gender and age demonstrate a statistically significant relationship with a particular dimension of mobile phone addiction, compulsive anxiety. The findings are expected to help practitioners delineate elaborated approaches aimed at relieving a dimension of the addiction-like symptoms of technology use. In addition, scholars can utilise dimensions composed of mobile phone addiction and self-traits to examine the detailed and respective causality that exists between them.

The estimation of workload is difficult and time consuming, and the result causes an unstable system and unnecessary message passing overhead. The structure of the load balancing system is composed of three design agents: the Load Index Agent (LIA), the Resource Management Agent (RMA) and the Load Transfer Agent (LTA). It is observed that the fuzzy-RMLB exhibits better adaptability, robustness, and fault-tolerant capability, thus yielding better performance compared to other existing algorithms.

However, some intermediate nodes may refuse to forward packets to other nodes or discard route-discovery requests from others to save power, as much as those consumed during the message transmission phase. In order to prevent node sel?shness, we have proposed a novel approach to message security using a payment-based mechanism in MANETs. In this way, the proposed routing protocol with payment mechanism not only avoids the sel?sh nodes that may refuse to route packets, but also restrains the nodes from sending useless packets into the networks. Finally, the proposed payment mechanism ensures ad hoc communications in a sel?ess environment by providing economic encouragement to enforce node cooperation in MANETs.
