This paper proposes an alternative model to deliver vital signs of patients in a hospital indoor environment where a large number of patients exist and the traffic generated rapidly changes over time using Body Area Network (BAN). The methodology for finding an optimal path includes a...

Wireless technology is widely spread everywhere in the real world and has a biggest contribution to mankind. However, with the vitality of wireless architectures, security protocols are vulnerable to attackers outside the system, failure in wireless connectivity and machine failures. Protocols...

In this article, the authors have proposed a secure two-factor remote user authentication and session key agreement protocol. As they have shown in the presented scheme, is precise and secure according to both formal and informal security analysis. For formal security analysis, they have applied...

In this paper, the authors have presented a (n, n) extended visual cryptography scheme where n numbers of meaningful shares furnish a visually secret message. Initially they have converted a grayscale image into binary image using dithering method. Afterwards, they have incorporated pixel's...

Wireless local area networks (WLANs), like IEEE 802.11, are right now very common in numerous outdoor or indoor environments for providing wireless communication among WiFi-enabled devices by accessing an Access Point (infrastructure mode) or through peer to peer connections (ad hoc mode)....
