Performance Analysis of Network Coding Schemes in Network Assisted D2D Communications

Network assisted device-to-device (D2D) communication can increase the spectrum and energy efficiency of proximity communication sessions in cellular networks. For cellular networks supporting D2D communications, network coding (NWC) has been proposed as a means to further increase the spectral and energy efficiency. Specifically, 2 time slot (2-TS) NWC has been shown to be a viable complement to D2D capable cellular networks. In this poster, we consider a 3-TS NWC scheme as an additional technique and propose an adaptive mode selection algorithm that is able to select between D2D mode without NWC, traditional cellular transmission, 2-TS NWC and 3-TS NWC. We use a realistic system simulator and show that the system with the extended NWC capability and mode selection outperforms existing D2D mode selection algorithms.
