Opportunistic Networks (OppNets) are a sub-class of DTN, designed as a specialized ad hoc network suitable for applications such as emergency responses. Unlike traditional networks, in OppNets communication opportunities are intermittent, so an end-to-end path between the source and the destination may never exist. Existing networks have already brought connectivity to a broad range of devices, such as hand held devices, laptops, tablets, PC, etc. The Internet of Things (IoT) will extend the connectivity to devices beyond just mobile phones and laptops, but to buildings, wearable devices, cars, different things and objects. One of the issues for these networks is the selection of the IoT nodes to carry out a task in OppNets. In this work, we implement two Fuzzy-Based Systems: Node Elimination System (NES) and Node Selection System (NSS) for IoT node elimination and selection in OppNets. We use three input parameters for NES: Node’s Distance to Event (NDE), Node’s Battery Level (NBL), Node’s Free Buffer Space (NFBS) and four input parameters for NSS: Node’s Number of Past Encounters (NNPE), Node’s Unique Encounters (NUE), Node Inter Contact Time (NICT), Node Contact Duration (NCD). The output parameter is IoT Node Selection Possibility (NSP). The results show that the proposed systems make a proper elimination and selection decision for IoT nodes in OppNets.

模糊逻辑在机会网络中物联网节点消除和选择中的应用:两个基于模糊系统的性能评估

机会网络(OppNets)是DTN的子类,被设计为适用于诸如应急响应之类的专用自组织网络。与传统网络不同,OppNets中的通信机会是断断续续的,因此源和目标之间的端到端路径可能永远不存在。现有网络已经将连接性带到了广泛的设备中,例如手持设备,便携式计算机,平板电脑,PC等。物联网(IoT)将使连接性扩展到设备,不仅限于移动电话和笔记本电脑,还包括建筑物。 ,可穿戴设备,汽车,其他事物和物体。这些网络的问题之一是选择IoT节点以在OppNets中执行任务。在这项工作中,我们实现了两个基于模糊的系统:OppNets中用于物联网节点消除和选择的节点消除系统(NES)和节点选择系统(NSS)。我们使用NES的三个输入参数:节点到事件的距离(NDE),节点的电池电量(NBL),节点的可用缓冲区空间(NFBS)和NSS的四个输入参数:节点的过去遇到次数(NNPE),节点的唯一遇到次数( NUE),节点间联系时间(NICT),节点联系持续时间(NCD)。输出参数是IoT节点选择可能性(NSP)。结果表明,所提出的系统为OppNets中的IoT节点做出了适当的消除和选择决策。节点的唯一遇到(NUE),节点间联系时间(NICT),节点联系持续时间(NCD)。输出参数是IoT节点选择可能性(NSP)。结果表明,所提出的系统为OppNets中的IoT节点做出了适当的消除和选择决策。节点的唯一遇到(NUE),节点间联系时间(NICT),节点联系持续时间(NCD)。输出参数是IoT节点选择可能性(NSP)。结果表明,所提出的系统为OppNets中的IoT节点做出了适当的消除和选择决策。
