An application of meta-heuristic and nature-inspired algorithms for designing reliable networks based on the Internet of things: A systematic literature review

The widespread use of Internet of Things (IoT) in various wireless sensor networks applications has increased their importance in recent years. IoT is a smart technology that connects anything anywhere at any time. These smart objects, which connect the physical world with the world of computing infrastructure, are expected to permeate all aspects of our daily lives and revolutionize a number of application domains such as healthcare, energy conservation, and transportation. As wireless networking expands, the disadvantage of wireless communication is clearly obvious. People's apprehension over the IoT's dependability has therefore skyrocketed. IoT networks' key requirements are dependability, channel security, fault tolerance, and reliability. Monitoring the IoT networks depends on the availability and correct functioning of all the network nodes. Recent research has proposed promising solutions to address these challenges. This article systematically examines recent articles that use meta-heuristic and nature-inspired algorithms to establish reliable IoT networks. Eighteen articles were analyzed in four groups. Results showed that reliable enhancement mechanisms in IoT networks increase fault node detection, network efficiency, and lifetime and attain energy optimization results in the IoT concept. Additionally, it was discovered in the literature that the current studies focus on how to effectively use edge network capabilities for IoT application executions and support, along with the related needs.

H-SPREAD: a hybrid multipath scheme for secure and reliable data collection in wireless sensor networks

Communication security and reliability are two important issues in any network. A typical communication task in a wireless sensor network is for every sensor node to sense its local environment, and upon request, send data of interest back to a base station (BS). In this paper, a hybrid multipath scheme (H-SPREAD) to improve both the security and reliability of this task in a potentially hostile and unreliable wireless sensor network is proposed. The new scheme is based on a distributed N-to-1 multipath discovery protocol, which is able to find multiple node-disjoint paths from every sensor node to the BS simultaneously in one route discovery process. Then, a hybrid multipath data collection scheme is proposed. On the one hand, end-to-end multipath data dispersion, combined with secret sharing, enhances the security of the end-to-end data delivery in the sense that the compromise of a small number of paths will not result in the compromise of a data message in the face of adversarial nodes. On the other hand, in the face of unreliable wireless links and/or sensor nodes, alternate path routing available at each sensor node improves the reliability of each packet transmission significantly. The extensive simulation results show that the hybrid multipath scheme is very efficient in improving both the security and reliability of the data collection service seamlessly.     

A lightweight IoT‐based security framework for inventory automation using wireless sensor network

Internet of things (IoT) has evolved as an innovation of next generation in this world of smart devices. IoT tends to provide services for data collection, data management, and data and device security required for application development. Things or devices in IoT communicate and compute to make our lives comfortable and safe. In inventory automation, real‐time check on items, their information management, and status management, monitoring can be carried out using IoT. The huge amount of data that flows among the devices in the network demands for a security framework that ensures authentication, authorization, integrity, and confidentiality of data. The existing security solutions like SIMON or SPECK offer lightweight security solutions but are vulnerable to differential attack because of their simplicity. Moreover, existing solutions do not offer inbuilt authentication. Therefore, this research work contributes a secure and lightweight IoT‐based framework using wireless sensor network (WSN) as a technology. The existing security solutions SPECK and SIMON are compared with the proposed security approach using COOJA simulator. The results show that proposed approach outstands others by 2% reduction in number of CPU cycles, 10% less execution time, 4% less memory requirements of security approach, and with minimum 10% more security impact.     

Internet of Things-based wireless sensor networks for monitoring access constraint security measures in liable data aggregation

A wireless sensor network (WSN) is a network of autonomous, small sensors that can detect, collect, and send data about their surrounding environment. In the Internet of Things (IoT) infrastructure, WSNs are the smart devices that provide the platform with resource input. Security breaches and insider attacks are possible due to the WSN's resource-constrained design. However, the IoT platform's intelligence may be extended to WSN nodes for managing device and data-level security. This paper proposes Monitored Access Constraint Security (MACS) to ensure the privacy of data collected via the ubiquitous processing enabled by the Internet of Things. The IoT platform performs frequent checks on the quality of the interactions between the various nodes to ensure that they are functioning properly and that the sensor aggregation instances are accountable. Node liability is considered while adjusting the aggregate level and the continuity. The method guarantees secure information from the environment and the data sources. The quality of the data gathered in the suggested technique is evaluated based on node liability and information extraction feature. Accordingly, security measures are implemented at data gathering and filtering levels and then assessed using a recurrent learning process. Since there are fewer security breaches overall, the rate of aggregation increases. Aggregation loss, delay time, false rate, throughput, and verification time are used to evaluate the performance.

Secure multi‐factor remote user authentication scheme for Internet of Things environments

Because of the exponential growth of Internet of Things (IoT), several services are being developed. These services can be accessed through smart gadgets by the user at any place, every time and anywhere. This makes security and privacy central to IoT environments. In this paper, we propose a lightweight, robust, and multi‐factor remote user authentication and key agreement scheme for IoT environments. Using this protocol, any authorized user can access and gather real‐time sensor data from the IoT nodes. Before gaining access to any IoT node, the user must first get authenticated by the gateway node as well as the IoT node. The proposed protocol is based on XOR and hash operations, and includes: (i) a 3‐factor authentication (ie, password, biometrics, and smart device); (ii) mutual authentication ; (iii) shared session key ; and (iv) key freshness . It satisfies desirable security attributes and maintains acceptable efficiency in terms of the computational overheads for resource constrained IoT environment. Further, the informal and formal security analysis using AVISPA proves security strength of the protocol and its robustness against all possible security threats. Simulation results also prove that the scheme is secure against attacks.

无线传感网络中基于非抗窜扰智能卡的双因素认证协议

智能卡是最为常见的密码设备之一,因其抗窜扰特性,智能卡常常被用于电子商务、医疗健康以及物联网等高安全需求的领域中为安全提供服务。随着侧信道攻击、逆向工程等技术的发展,研究表明智能卡内保存的参数可恢复,使其不再具有抗窜扰特性,因而,基于非抗窜扰智能卡假设的多因素认证协议设计得到了广泛的关注。为此,研究了在无线传感网络中典型的多因素协议,指出其不能抵抗离线口令猜测攻击和中间人攻击、无法实现双向认证,以及不能抵抗离线口令猜测攻击、无法实现用户匿名性等问题。为克服这些缺陷,在非抗窜扰智能卡假设下,结合哈希链技术提出了一类面向无线传感器网络的双因素认证协议,并在随机预言机模型中给出了严格的安全证明。与现有无线传感网络环境下多因素认证协议相比,该协议在保持较低计算开销的同时,实现了更高的安全性,适于资源受限的无线传感器网络环境。
