Survey on Network Slicing for Internet of Things Realization in 5G Networks

Abstract

Internet of Things (IoT) is an emerging technology that makes people's lives smart by conquering a plethora of diverse application and service areas. In near future, the fifthgeneration (5G) wireless networks provide the connectivity for this IoT ecosystem. It has been carefully designed to facilitate the exponential growth in the IoT field. Network slicing is one of the key technologies in the 5G architecture that has the ability to divide the physical network into multiple logical networks (i.e. slices) with different network characteristics. Therefore, network slicing is also a key enabler of realisation of IoT in 5G. Network slicing can satisfy the various networking demands by heterogeneous IoT applications via dedicated slices. In this survey, we present a comprehensive analysis of the exploitation of network slicing in IoT realisation. We discuss network slicing utilisation in different IoT application scenarios, along with the technical challenges that can be solved via network slicing. Furthermore, integration challenges and open research problems related to the network slicing in the IoT realisation are also discussed in this paper. Finally, we discuss the role of other emerging technologies and concepts, such as blockchain and Artificial Intelligence/Machine Learning(AI/ML) in network slicing and IoT integration.

AI and 6G Security: Opportunities and Challenges

“…Due to the massively distributed nature of 6G systems, MEC in 6G is subjected to physical security threats, Distributed Denial of Service (DDoS), man-in-the-middle attacks [9]. Potential attacks for network slicing are DoS attacks, information theft via compromised slices [10]. Attacks on network softwarization technologies fail the 6G network from achieving the promised dynamicity and full automation.…”

5G Campus Networks: A First Measurement Study

“…Numerous emerging technological paradigms, such as Industry 4.0 [1]- [3], Internet of Things (IoT) [4]- [6], and self-driving vehicles [7]- [10], require reliable low-latency communication that is untethered from cables [11], [12]. Proponents of these new technological paradigms have often deferred the provisioning of these required reliable lowlatency wireless communication services to the 5th Gener-ation (5G) mobile communication standard developed by the Third Generation Partnership Project (3GPP) [13]- [15].…”

Conceptual Evaluation of a 5G Network Slicing Technique for Emergency Communications and Preliminary Estimate of Energy Trade-Off

“…Following the description of the Katana slicing framework [9], a set of experiments were carried out to evaluate the impact of slicing technologies [10] regarding the energy domain. Katana was previously evaluated in terms of performance in [11,12] and achieved end-to-end latency down to ~10 ms. Related studies [13][14][15][16] have defined the minimal requirement for end-to-end URLLC slicing to be at 20 ms [17,18]; therefore, the presented work significantly improves expected latency performance. For the needs of these experiments, a 5G system configured in Standalone Mode (SA) was used, with a set of 5 UEs.…”
