Deployment of sensor nodes with full coverage and connectivity is a real challenge in the field of Wireless Sensor Networks. In this paper we have done a comparative study to reach an optimum deployment solution without compromising coverage as well as the connectivity of a region using a layered deployment model. We have also presented the optimal coverage(More)
Visual Cryptography is a special type of encryption technique to obscure image-based secret information which can be decrypted by Human Visual System. There have various approaches developed for encrypting image. The former being encrypting the images through encryption algorithms using keys, and the later approach involves dividing the image into random(More)
