Nearest neighbor mobile social network means that movers approaching in position communicate through their social sensors, which is called Proximity Mobile Social Network. Proximity Mobile Social Network can provide more social and business opportunities for users. To carry out disaster relief work in post-disaster environment, we need to collect incident information during the search process and report to the sink in time. Proximity Mobile Social Network provides flexible systems for emergency handling and disaster relief. Therefore, how to find a better data forwarding and routing strategy is the key problem of post-disaster rescue, and the research of user mobility model is the basis of the above problems. This article presents an Autonomy-Oriented Proximity Mobile Social Network modeling for emergency rescue in smart city, which simulates the network operating environment. First, we verify the performance of Autonomy-Oriented Proximity Mobile Social Network model in terms of self-organization, scale-free, aggregation, and community structure. Then, the rescue efficiency is discussed through the coverage of mobile sensors. Finally, performance of the routing strategy based on Autonomy-Oriented Proximity Mobile Social Network model is analyzed, and the effectiveness of the method is proved.

Social Network Modeling

Social network modeling is generally based on graph theory, which allows for study of dynamics and emerging phenomena. However, in terms of neighborhood, the graphs are not necessarily adapted to represent complex interactions, and the neighborhood of a group of vertices can be inferred from the neighborhoods of each vertex composing that group. In our study, we consider that a group has to be considered as a complex system where emerging phenomena can appear. In this paper, a formalism is proposed to resolve this problematic by modeling groups in social networks using pretopology as a generalization of the graph theory. After giving some definitions and examples of modeling, we show how some measures used in social network analysis (degree, betweenness, and closeness) can be also generalized to consider a group as a whole entity.

Technical Terms

Earlier engineering was done by few people. But now with ever increasing knowledge base with the public, there is need to tap that source. But this tapping of knowledge base of the public cannot be done in technical terms. There is need to express knowledge in non technical terms by use of logical reasoning, modeling of ideas, etc. Seeing these non technical details on website, some people can even put their responses, or ask for clarification of some points. Now if designers see this information they can answer those queries. Modern engineering is not limited to the handful designers alone, country has a large knowledge base in public, but a company cannot hire all people, so there needs to place a mechanism by which designers can come in contact with the people, understand and incorporate their feedback and answer their queries.Quality control tools (like flowchart, Cause-effect or fishbone diagrams, force field analysis, interrelations digraph, affinity diagram, and variability matrix) have been quite popular as they explain the engineering processes in a non technical way, yet they analyze the underlying process thoroughly.With the advent of modern computers, a new paradigm has been opened in terms of Social Network analysis, which connects people in a faster manner and lead to quicker information flow. In this project we propose to use the above mentioned Quality Control tools with Social Network modeling concepts to bring every bit of information available with the people at lower working level in a systematic and structured manner in the front of senior decision making level.

Strong Consensus

In this work, we consider a system of coupled finite-difference equations which incorporates a variety of opinion formation models, and use it to describe the dynamics of opinions on controversial subjects. The social network consists of a finite number of agents with pairwise interactions at discrete times. Meanwhile, the opinion of each agent is updated following a general nonlinear law which considers parameters identified as the personal constants of each of the members. We establish conditions that guarantee the existence of global attracting points (strong consensus) and intervals (weak consensus). Moreover, we note that these conditions are independent of the weight matrix and the number of agents of the network. Two particular scenarios are investigated numerically in order to confirm the validity of the analytical results.
