“…This enhancement mainly refers to inclusion of all symbols having ASCII values between 0 and 255. Further, authors in [9][10] [11][12] [13] can consider introducing transposition to their proposed algorithms to improve security. We could also consider different transposition algorithms to be combined with playfair cipher.…”

With the growing importance of transmitting data over the network, data encryption is becoming critical. Encryption helps safeguarding the data transmitted over the network from an unwanted entity. The two methods to encrypt data are-Substitution and Transposition. Transposition refers to changing the position of characters in a given text. On the other hand, substitution is the process of replacing each character of the plaintext with some other character. Playfair cipher is an illustration of substitution cipher. The classical playfair cipher has a 5x5 matrix. To increase the resistance of playfair cipher, this paper proposes to introduce double Myszkowski transposition on a modified 6x6 playfair matrix. The 6x6 matrix includes the all the alphabets along with the single digit numbers. A comparison with the classical 5x5 playfair cipher proves the enhanced security of the proposed algorithm.

During the past few years, interest has grown in the creation and application of methods, structures for smart city evaluation. This reflects the increasing awareness of the value of systems for better planning and architecture of efficient and stable communities. A city is a vast and permanent human community that offers many resources and opportunities for its people. The rapid urbanization and growth have put a lot of pressure on local services and service delivery. The research discusses many potential resources that can make a city smart across growing city dimensions and also discusses the initiatives of the Indian government towards a Smart city. This paper is a survey of a variety of papers, covering the actual case study from a more comprehensive framework, such as e-mobility, which covers the smart city subject from.

Wireless sensor networks (WSNs) have limited storage capacity, communication bandwidth, processing speed, and battery issues. All these factors affect the lifespan of a WSN. Solving all these issues and increasing the lifespan of the WSN. Energy optimization in WSNs is a demanding issue that drives a huge effort in research and various standardization procedures have been undertaken in this area for the past several years. To deal with the reduction of energy consumption issues in WSNs, various clustering protocols have evolved. In this context, some protocols select an appropriate node as the cluster head to extend the lifespan of the network and also clustering reviewed techniques. In this paper, different fuzzy-based clustering methods are discussed which is helpful in designing novel energy-efficient fuzzy-based routing protocols for WSN. The main purpose of this article is to review different types of routing protocols with their advantages and limitations. In addition, various protocols have been compared graphically with their lifetimes. Various tables are depicted which are helpful for extended studies, graphical comparison between the latest clustering techniques shows the most suitable clustering technique for improving network lifetime.
