Visual Cryptography is a special type of encryption technique to obscure image-based secret information which can be decrypted by Human Visual System (HVS). It is a kind of secret-sharing scheme that encrypts the secret image into n number of shares. It is imperceptible to reveal the secret information unless a certain number of shares(k) or more are(More)
MEMS-based programmable oscillators have emerged as a promising alternative to crystal-based frequency references, with previously reported work demonstrating sub-ps integrated jitter [1]. Here we show frequency stability better than ±0.5ppm from-40 to 85°C, along with Allan Deviation (i.e., long term jitter) better than 0.005 ppm for 0.1, 1, and 10 second(More)
Recently, wireless mesh networks (WMNs) technology has gained a lot of attention in network research community. WMN is a multi-hop wireless access network where nodes can act both as a router as well as a host. One of the factors that influence the performance of WMNs is the underlying routing protocol used. Thus, numbers of different multipath routing(More)
