We propose a new symmetric block cipher encryption which provides confidentiality to the multimedia while transmitting through the network. The encryption relies on two typical operations, substitution and transposition. A complete binary tree performs substitution and a 2-d array performs non-linear diffusion in the 2 stage of the encryption/decryption process. The first stage spreads out the bits...
Due to the very nature of modern day Smartphone's and tablets, users of such devices will often travel from an area with strong mobile signal to a weaker area. Travelling from a Strong Signal Area (SSA) to a Weak Signal Area (WSA) causes a significant drop in the mobile network bandwidth available to the device. This causes Quality of Service (QoS) problems for video streams over mobile networks....
For the wide area surveillance various ip-based sensors should collaborate to understand the situation. It consists of transferring of huge multimedia data as well as feature data recognized. Cognitive multi-agent systems on sensors retrieve and classify features extracted from images and videos. To enable collaborative reasoning between agents on sensors, interoperable sensor data deployment scheme...
