“…In [201], the authors suggest an algorithm for retrieving and storing information on WSNs in post-disaster scenarios to help the rescue team. To improve the delivery of mission critical data, human intelligence is embedded in a wireless sensor network where the network coordinator can detect the critical data and sets an emergency flag at its next beacon to inform the nodes [202].…”

The performance of wireless communication network is important in emergency rescue operations while ensuring optimum usage of limited wireless resources. Due to the disruption of normal wireless communication in a post-disaster scenario, the sustenance of an emergency communication network plays a significant role in relief operations. Under such a scenario, it becomes crucial to monitor the performance and reliability of the protocol in a time-bound manner. Some of the prominent challenges faced by the communication network during this period are related to energy efficiency, resources allocation, reliable connectivity, QoS, network throughput, and interoperability. A comprehensive performance appraisal of the emergency network considering the above-mentioned aspects is extremely important. This review provides a comprehensive survey of the widely used communication technologies applied for setting up an emergency communication network to mitigate the post disaster aftermath. The article also delivers an overview of the integration of new technologies with the existing standards for improving the performance of the disaster communication networks. Finally, we propose some promising solutions to overcome the limitations of existing emergency communication technologies to improve the overall network performance.

“…In recent years, the use of Inductive Power Transfer (IPT) has increased in many applications where cables are not desired or cannot be used, such as medical implants [1], wireless sensor nodes [2], smart textile wearable devices [3], electrical vehicles [4], and robots [5]. Typically, IPT systems are based on coupled-mode theory in an oscillating electromagnetic field with a transmitter coil (TX) and a receiver coil (RX), respectively.…”

Inductive wireless power transfer is a promising technology for powering smart wearable devices. The spiral coil shape is widely used in wireless power transfer applications. Nevertheless, during the coil design process, there are many challenges to overcome considering all the design constraints. The most important is to determine the optimal coil parameters (internal radius, external radius, spacing, wire width, and conductive wire) with the aim of obtaining the highest coil quality factor. Coil modeling is very important for the wireless power transfer system’s efficiency. Indeed, it is challenging because it requires a high computational effort and has convergence problems. In this paper, we propose a new approach for the approximation of spiral coils through concentric circular turns to reduce the computational effort. The mathematical model determines the optimal coil parameters to obtain the highest coil quality factor. We have chosen the smart textile as an application. The system operates at a frequency of 100 Khz considering the Qi guidelines. To validate this approach, we compared the approximated circular coil model with the spiral coil model through a finite element method simulation using the COMSOL software. The obtained results show that the proposed approximation reduces the complexity of the coil design process and performs well compared to the model corresponding to the spiral shape, without significantly modifying the coil inductance. For a wire width smaller than 1 mm, the total deviation is around 4% in terms of the coil quality factor in a predetermined domain of its parameters.

“…Ordinary smart grid users can view and manage other electric devices at home through the meter, and equipment maintainers upgrade and maintain the grid devices by upgrading them. Depending on the functions of the grid customers in the smart grid, the grid users have different access rights to the smart devices, and in this smart grid system with multiple devices can access these grid devices accordingly according to the needs of the grid customers in different roles and modification operations according to the needs of different roles of grid customers [6][7][8][9][10]. Quantum computing will potentially enable the computational power of ordinary computers to greatly exceed the present computational power, and in 1997, Shor et al proposed quantum algorithms for solving the decomposition of large integers and discrete logarithms and demonstrated that the time complexity of their algorithmic operations is of polynomial level [11].…”

At present, the smart grid has become one of the indispensable infrastructures in people's lives. As a commonly used communication method, wireless communication is gradually, being widely used in smart grid systems due to its convenient deployment and wide range of serious challenges to security. For the insecurity of the schemes based on large integer factorization and discrete logarithm problem in the quantum environment, an identity-based key management scheme for smart grid over lattice is proposed. To assure the communication security, through constructing intra-cluster and inter-cluster multi-hop routing secure mechanism. The time parameter and identity information are introduced in the relying phase. Through using the symmetric cryptography algorithm to encrypt improve communication efficiency. Through output the authentication information with probability, the protocol makes the private key of the certification body no relation with the distribution of authentication information. Theoretic studies and figures show that the efficiency of keys can be authenticated, so the number of attacks, including masquerade, reply and message manipulation attacks can be resisted. The new scheme can not only increase the security, but also decrease the communication energy consumption.
