摘要: In this letter, the issue of security for device-to-device (D2D) underlaying cellular networks is considered. The communication overheard by randomly distributed eavesdroppers. By sharing spectrum between D2D users and users, interference generated used as a source jamming to confuse We first derive connection probability links secrecy outage link based on stochastic geometry tools. then propose joint guard zone threshold-based access control scheme maximize achievable throughput. Moreover, when only selection threshold considered, closed-form expression optimal derived. Simulation results show that improved throughput can be achieved allowing transmission users.
