Clustering based opportunistic traffic offloading technique for device-to-device communication

Device-to-device communication attracts the research community due to its diversifying range of applications. Device-to-device communication occurs between two devices without any aid from the base station. Thus, it helps in providing connectivity in low connectivity areas. In this article, authors proposed a new technique named as Clustering Based Opportunistic Traffic Offloading (CBOT), for Device-to-device communication. The proposed CBOT technique divided the network into small clusters and used a hybrid scheme for data transmission. To improve the energy consumption and throughput of the system, authors have proposed cluster formation, cluster head selection, and rotation techniques. The simulation results show that CBOT improves network lifetime by achieving high energy efficiency and increased system performance by achieving higher throughput. Further, the performance of CBOT tested under opportunistic networks scenario and simulation results demonstrate that the proposed approach improves energy consumption and throughput in a better way than the existing approaches.
