Abstract
Device-to-device (D2D) communication is one of the promising technologies for the next-generation cellular network, which uses direct communication between two neighboring devices to obtain a high transmission rate. This paper focuses on wireless resource allocation in a many-to-many D2D communication scenario to maximize the D2D transmission sum rate. Through the model analysis, the objective function is formulated while guaranteeing the minimum transmission rate of both the cellular users (CUs) and the D2D pairs. Based on the candidate sequence, an overlapping coalition game algorithm is proposed to enhance the D2D transmission sum rate. Furthermore, the preference sequence of CUs is adopted in the coalition initialization. According to the interference intensity, a power allocation scheme is designed further to improve the transmission sum rate of the D2D pairs. The simulation results have verified the validity of the proposed algorithm.
Highlights
With the rapid development of the Internet of Things (IoT) and cellular technology, the demand for mobile internet access is growing at a tremendous rate in the past decade [1,2,3]
The interferences will be more serious in many-to-many scenario, where one channel resource can be reused by multiple Device-to-device cellular users (CUs) (D2D) pairs, and a D2D pair can reuse multiple channel resources
This paper mainly focuses on the resource allocation and power control in many-to-many D2D communication, which is different from reported works, such as the random selection [13], cooperative game [14], or matching game with externalities [15] to reuse the channel resources and improve the D2D transmission sum rate
Summary
With the rapid development of the Internet of Things (IoT) and cellular technology, the demand for mobile internet access is growing at a tremendous rate in the past decade [1,2,3]. This paper mainly focuses on the resource allocation and power control in many-to-many D2D communication, which is different from reported works, such as the random selection [13], cooperative game [14], or matching game with externalities [15] to reuse the channel resources and improve the D2D transmission sum rate. An overlapping coalition game algorithm based on the candidate sequence is proposed to further enhance the D2D transmission sum rate in this work. (1) In a many-to-many scenario, the system model was analyzed, and the sum transmission rate of D2D pairs with guaranteeing the quality of service (QoS) was formulated as the objective function (2) An overlapping coalition game algorithm based on the candidate sequence was proposed to guide the channel resource allocation, which could enhance the transmission rate of D2D pairs. For the sake of convenience, the major symbols used in this paper are listed in Table 1 with their definitions
