Social Opportunistic IoT (Social OppIoT) networks is a subclass of Social Internet of Things (SIoT) networks. In social OppIoT, users perform communication in a distributed manner using smart devices by regularly moving around without any communication infrastructures, making routing a strenuous process due to its highly fragile connection intermittency and device mobility. Moreover, due to the growing heterogeneous devices, problems can exist in searching for the right relay node from a massive number of devices. In this paper, a novel forwarding scheme named “A Local Betweenness Centrality Based Forwarding Technique for Social Opportunistic IoT Networks” (LBCFT) has been proposed, which uses a reduction strategy to discard the inefficient devices. LBCFT introduces a new centrality measurement called local betweenness centrality to form the significant overlapping communities of network devices to boost forwarding. Message dissemination is controlled by handling inefficient devices using a reduction strategy, which includes the node’s trajectory and intra-community and inter-community centrality. The performance of LBCFT is evaluated through ONE Simulator against the existing analogous ideologies like Supernode, Geo-Routing with Angle-based Decision (GRAD), and the benchmark protocols BubbleRap, as well as PROPHET. The simulation results show that the proposed LBCFT protocol, on average, outperforms Supernode, GRAD, BubbleRap, and PROPHET by 5.22%, 36.51%, 64.12%, and 57.96% respectively, in terms of the delivery probability.

一种基于局部中介中心性的社会机会物联网网络转发技术

社交机会物联网 (Social OppIoT) 网络是社交物联网 (SIoT) 网络的一个子类。在社交OppIoT中,用户使用智能设备以分布式方式进行通信,在没有任何通信基础设施的情况下定期移动,由于其高度脆弱的连接间歇性和设备移动性,使得路由成为一个繁重的过程。此外,由于不断增长的异构设备,在从大量设备中搜索正确的中继节点时可能存在问题。在本文中,提出了一种名为“基于局部中介中心性的社交机会物联网网络转发技术”(LBCFT)的新型转发方案,该方案使用减少策略来丢弃低效设备。LBCFT 引入了一种新的中心性度量,称为本地中介中心性,以形成网络设备的重要重叠社区以促进转发。消息传播是通过使用减少策略处理低效设备来控制的,其中包括节点的轨迹以及社区内和社区间的中心性。LBCFT 的性能通过 ONE Simulator 针对现有的类似意识形态(如超级节点、基于角度的决策的地理路由(GRAD)、基准协议 BubbleRap 以及 PROPHET)进行评估。仿真结果表明,所提出的 LBCFT 协议平均优于 Supernode、GRAD、BubbleRap 和 PROPHET 5.22 消息传播是通过使用减少策略处理低效设备来控制的,其中包括节点的轨迹以及社区内和社区间的中心性。LBCFT 的性能通过 ONE Simulator 针对现有的类似意识形态(如超级节点、基于角度的决策的地理路由(GRAD)、基准协议 BubbleRap 以及 PROPHET)进行评估。仿真结果表明,所提出的 LBCFT 协议平均优于 Supernode、GRAD、BubbleRap 和 PROPHET 5.22 消息传播是通过使用减少策略处理低效设备来控制的,其中包括节点的轨迹以及社区内和社区间的中心性。LBCFT 的性能通过 ONE Simulator 针对现有的类似意识形态(如超级节点、基于角度的决策的地理路由(GRAD)、基准协议 BubbleRap 以及 PROPHET)进行评估。仿真结果表明,所提出的 LBCFT 协议平均优于 Supernode、GRAD、BubbleRap 和 PROPHET 5.22 以及先知。仿真结果表明,所提出的 LBCFT 协议平均优于 Supernode、GRAD、BubbleRap 和 PROPHET 5.22 以及先知。仿真结果表明,所提出的 LBCFT 协议平均优于 Supernode、GRAD、BubbleRap 和 PROPHET 5.22%、 36.51 %、 64.12 %和 57.96 %,就交付概率而言。
