In the fast-moving world, it is noticed that every industry is developing gradually, but recently it is identified that the use of AI has become the talk of own. Therefore, this study is focused on gathering data regarding the AI on how it has transformed the entire world's corporate sector. The essential application AI in the business world helps the business to perform better in the corporate sector. In this paper, the critical role of artificial intelligence is to grow business in different sectors and also address its ethical and unethical issues. The paper has all the initial background and comprehensive literature regarding AI and machine learning. It is discovered how the technological world has been striving to take their business on to new heights, which requires updated technological changes in internal business activities. Companies can now effortlessly interact with their customers in making their application accessible for the end-users through implementing AI and machine learning. Companies are getting higher profitability and enhancing their performance and achieving economic advantages by integrated AI. Moreover, their technological developments will take human jobs in the future, so, it is suggested that humans should work on their skills and competencies so that they can deal with unemployment.

Mobile communication systems employ an encoding-encryption model to ensure secure data transmission over the network. This model encodes the data and encrypts it before transmitting it to the receiver's end. A non-trivial operation is performed to generate a strong secret key through which the data is encrypted. To support the security level of this model, arithmetic encoding is performed upon the data before encryption. The encrypted data is hashed using a lightweight hashing algorithm to generate a small and fixed length hash digest to overcome the overheads before it is communicated to the other end. To authorize the message being sent by the sender to the receiver, signature plays an important role. To avoid forging using proxy signature, blind signature, etc., a hybrid scheme is proposed in this article. The mobile communication system is enhanced by introducing the hybrid encode-encrypt-hashing mechanism which stands secure against the plain text attacks, mathematical attacks, and increases confidentiality of the data, security of the key, and thereby enhances the security of the system. In this paper, the design is applied over the mobile payment system which is considered as one of the appreciable mobile services. It proves that the designed security model can ensure swift transactions in a secure way.

Wireless sensor network comprises of scattered sensors to sense, monitor and aggregate the sensed information. The major issue in a wireless sensor network is to balance network load and to maintain less energy consumption where multi parent crossover method is considered. Multiparent cross over method will generate offspring from parent and aims at managing the load. In this paper a comparative study of different algorithms is done where the load balancing and energy consumption issue has been resolved.

A mobile Ad Hoc network (MANET) is aself-configuring, structure-less network of devices connected wirelessly. The disseminated nature of MANETs signifiesaunrivaledresponsibility to security architects. Key management is essential part of securitythis issue is considerably greater in MANETs. In view of dynamic nature of MANETs, when a node leaves or goes along with it have to produce new session key to hold forward and backward secrecy. Our proposed scheme focus in: 1) Cluster establishment 2) Link consistency 3) Cluster key Generation. The individual node residences are proven andthe nodes are ordered into clusters totally on their transmission series. Utilizing this, an advanced technique is invoked for the cluster head determination and cluster development. The proposedscheme saves time and vitality for common cluster updations and key updations. . To prevent the non-group memberships from deciphering the information, complicated key called Group Key is being created. The confidentiality of the Group key is being maintained. Group key evadethe issue of authentications and third partyparticipation. Recurrent updations, the chance of key hacking and replacing certificates are being decreased. The outcomes demonstrate that the throughput, existence time of the nodes, link consistency is expanded with least utilization of vitality. Our proposed scheme additionally reduces overhead, end-end delay and packet loss. The quantity of key updations is being reduced in our proposed framework and link consistency is retained.
