Energy optimization through duty cycling scheduling in mobile social networks: A non-cooperative game theory approach

Abstract

Recent advances in short range wireless communications along with exponential growth of the number of mobile devices are key factors for the emergence and development of Mobile Social Networks. Indeed, using proximity based approach to disseminate social content among individuals will reduce the load on the telecommunication operator infrastructure and will speedup the availability of the content among communities with common interests. Since content dissemination in Mobile Social Networks (MSNs) is intrinsically related to the mobility pattern of the users. Efficient dissemination protocols become a decisive issue. Mobile devices are battery powered, hence, energy consumption optimization is a critical issue to consider when deploying MSNs. Duty cycling is a well investigated approach to reduce energy consumption and prolong lifetime of mobile devices. In this paper we study the scheduling of active/idle cycles under Two-Hop social content dissemination protocol. We provide a game theoretical formulation of the problem and investigate the proposed activation game structural properties. We also study existence and uniqueness game solution and provide learning algorithm that ensure convergence of the studied MSN to this equilibrium operating point.
