Abstract

Network traffic generation is one of the primary techniques that is used to design and analyze the performance of network security systems. However, due to the diversity of IoT networks in terms of devices, applications and protocols, the traditional network traffic generator tools are unable to generate the IoT specific protocols traffic. Hence, the traditional traffic generator tools cannot be used for designing and testing the performance of IoT-specific security solutions. In order to design an IoT-based traffic generation framework, two main challenges include IoT device modelling and generating the IoT normal and attack traffic simultaneously. Therefore, in this work, we propose an open-source framework for IoT traffic generation which supports the two widely used IoT application layer protocols, i.e., MQTT and CoAP. The proposed framework allows a user to create an IoT use case, add customized IoT devices into it and generate normal and malicious IoT traffic over a real-time network. Furthermore, we set up a real-time IoT smart home use case to manifest the applicability of the proposed framework for developing the security solutions for IoT smart home by emulating the real world IoT devices. The experimental results demonstrate that the proposed framework can be effectively used to develop better security solutions for IoT networks without physically deploying the real-time use case., Comment: 6 Pages, 2 Figures, 4 Tables.

27. Sustaining innovation during downsizing strategy through knowledge coupling, business process digitization, and market capitalizing agility.

Author

Abstract

COVID-19 has developed chaos and uncertainty for small and medium enterprises (SMEs) causing mass downsizing. Under such uncertainty, innovation is key to survival and agility to growth. This study examines role of knowledge coupling and business process digitization (BPD) in sustaining innovation through market capitalizing agility (MCA) besides downsizing strategy. Data have been collected from top and mid management of Chinese manufacturing SMEs and analyzed with knowledge-based view and self-tuning model through Smart-PLS 4. Knowledge coupling positively contributes to MCA and innovation irrespective of downsizing strategy. Effect of BPD on innovation performance is same; however, insignificant on MCA in no-downsizing sample. Likewise, MCA positively influences innovation performance and positively mediates between knowledge coupling (BPD) and innovation performance only during downsizing. This study is first of its kind to establish mediating effect of MCA between knowledge coupling (BPD) and innovation performance during downsizing phase and offers significant theoretical and practical implications.

Abstract

The presence of chemicals, heavy metals, and colorants from textile effluents in water represent a significant health risk. To address this, a range of treatment methods, including ion exchange, membrane processes, physicochemical approaches, and biological techniques, are employed to eliminate these contaminants. Activated carbon, distinguished by its porous structure and effective pollutant, is a notable solution. An environmentally sustainable method involves producing activated carbon from agricultural and industrial waste to combat water pollution. For instance, the recycling of industrial waste, like glass fiber-reinforced plastic, can be used for water treatment via pyrolysis with a ZnCl2 activation process. The quality of the activated carbon is confirmed through characterization methods such as XRD, FTIR, SEM, and Raman spectroscopy, suggesting potential applications extending beyond water filtration, encompassing supercapacitors, fuel storage, and CO2 absorption. This study underscores the environmentally friendly potential of repurposing industrial waste for efficient and eco-conscious water purification. [ABSTRACT FROM AUTHOR]
