Abstract
Recently, to reduce the increasing energy consumption along with the explosive growth of smart terminals and network data in Internet of Things (IoT), green IoT is attracting more and more attention from both academia and industry. Towards green IoT, this paper devotes attention to Device-to-Device (D2D) communication and social network which are two essential components in green IoT and first reviews the latest developments about them. Further, this paper proposes a social interaction assisted resource sharing scheme for D2D communication, to improve the utilization of spectrum resources in green IoT. Specifically, the proposed scheme abstracts the D2D communication system into social layer and physical layer, by combining social network with D2D communication. Extensive simulations with real social interaction data are conducted and they show that the proposed scheme can achieve improvements in terms of the transmission success rate for green IoT.
Highlights
In recent times, various smart terminals and massive network data are explosively growing in Internet of Things (IoT), which leads to that the energy consumption in IoT is increasing quickly
For resource sharing in D2D communication underlaying cellular network, first, Device i finds its nearby possible Devices N in the physical layer; and with social layer’s assistance, these N Devices will be ranked according to comprehensive judgment of holding probability that they cleave to the item j and transmission success rate
EVALUATION AND ANALYSIS the performance of the proposed social interaction assisted resource sharing scheme will be analyzed through experiments
Summary
Various smart terminals and massive network data are explosively growing in Internet of Things (IoT), which leads to that the energy consumption in IoT is increasing quickly. In this work, for the purpose of further improve the utilization of transmission energy and solve the problems of interference coordination between D2D communication and cellular network, we propose a social interaction assisted resource sharing scheme. Recent work about social network focuses on social aware assisted relay selection, and formulate corresponding secure transmission strategy to enhance network capacity and safety These approaches attempt to quantify users relationship through some abstract parameters, while might limit users autonomy in reality to some extent. Without effective resource allocation and interference management methods, the problem of system performance degradation caused by interference will largely limit the application of D2D technology in future communication scenarios For a period of time when the item is shared between different device users, it is assumed that one D2D pair can form a D2D link when it meets the constraints of specific success rate and transmission speed
