초록

본 논문에서는 기지국의 도움없이 인접한 기기 간에 직접 통신을 수행하는 D2D 단말에서 발생한 데이터를 인접한 D2D 단말로 릴레이하는 환경을 가정하였다. 이러한 환경에서 데이터를 수신한 전체 단말의 수를 최대화하기 위하여 모든 데이터 수신 단말들이 자신의 전송 범위 내의 인접 단말들에게 데이터를 릴레이하는 Epidemic 라우팅을 고려하였다. 또한, 다양한 네트워크 환경을 고려하여 특정 지역에 다양한 밀도로 단말이 밀집되어 분포하는 상황에 대한 MATLAB 시뮬레이션을 수행하고, 이를 기반으로 D2D SD의 전송 범위와 이 데이터를 릴레이 하는 다른 D2D 단말들의 전송 범위를 파라미터로 설정하여 Epidemic 라우팅의 데이터 확산 성능에 대한 비교 분석을 수행하였다.

In this paper, by using D2D communications that perform direct communications among devices within small transmission range of each device without base station, we assume that a device generates and transmits data packets to other proximate devices and the devices which receive the data packets relay those to other adjacent devices. To maximize the total number of devices which successfully receive data packets, Epidemic routing protocol is considered in this paper. In Epidemic routing protocol, all devices which received data packets try to relay the packets to other adjacent devices. We assume various network environment where devices are densely distributed in specific area(crowded area). In this environment, D2D SD can be a source node and D2D devices can be relay nodes. By setting transmission range of D2D SD and D2D devices as parameters, we analyze performance results of coverage probability of Epidemic routing protocol through intensive simulations.
