Weight distribution and community reconstitution based on communities communications in social opportunistic networks

Abstract

In social communication, mobile devices can be regarded as socialization nodes in social networks. Furthermore, they carry and store useful information. Mobile devices can select destination nodes and deliver messages through opportunistic networks because messages can be securely and conveniently stored, carried, and transmitted with nodes. However, many communities may deliver messages often depending on one or two nodes. If those nodes are not enough cache and over-flooding, data transmission in communities may wait for a long time. In this study, weight distribution between nodes and communities reconstitution would be established to solve this problem in social opportunistic networks. With satisfactory results from simulation and comparison with some existing algorithms, the new method is found to not only decrease tendency of energy consumption but also improve the delivery ratio, overhead and End-to-end delay in social opportunistic networks.
