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.

设备到设备的通信因其广泛的应用范围而吸引了研究界的注意。设备之间的通信发生在两个设备之间，而没有基站的任何帮助。因此，它有助于在低连接区域提供连接。在这篇文章中，作者提出了命名为新技术ç上光乙ASED Ø pportunistic ŧ流量卸载（CBOT），用于设备到设备的通信。提出的CBOT技术将网络划分为小集群，并使用混合方案进行数据传输。为了提高系统的能耗和吞吐量，作者提出了集群形成，集群头选择和旋转技术。仿真结果表明，CBOT通过提高能源效率来延长网络寿命，并通过提高吞吐量来提高系统性能。此外，在机会网络情况下测试的CBOT性能和仿真结果表明，与现有方法相比，所提出的方法以更好的方式改善了能耗和吞吐量。
