N2 - Device-to-Device (D2D) communication is one of the promising technologies in 5G wireless communication system. The concept of D2D communication is to allow the direct communications between two devices reusing the cellular spectrum. Considering the large scale D2D networks, where multiple D2D users can download common files (called content below) from one or multiple other users directly by reusing the same spectrum with cellular users (CU). In this paper, we propose the peer-to-peer (P2P) based resource allocation for D2D networks in which resource includes spectrum and content. We aim at maximizing the sum download rate based on jointly effective spectrum and content allocation. However, this problem is NP-hard. Thus, we firstly develop a distance constrained coalitional game to solve the optimal resource allocation problem. We formulate the optimal spectrum and content allocation as an utility maximization problem and distribute the utility based on each player's successful transmission probability (STP) which is derived by the tool of stochastic geometry. By theoretical analysis, we derive the proper constrained distance, prove that the proposed algorithm is Nash-stable and get the improvement of the convergence rate. By extensive simulation, we demonstrate the effectiveness of our proposed algorithm which obtains the best sum download rate comparing with other schemes and it is close to the optimal solution.
