Multimedia transmission over wireless networks is having multiple challenges. Recently the cross layer architecture and SVC technologies are the promising methods to support the wireless communication. The existing methods are not able to resolve the issues of data delivery delay and QoS of the wireless communication. To address this issue this paper introduces the QoS improvement scheme in video...
Medical imaging has grown tremendously over years. The CT and MRI are well thought-out to be most extensively used imaging modalities. MRI is less dangerous, but one cannot underrate the unsafe side effects of CT. Current study reveals the actuality of escalating risk of cancer as side effect for patients who go through recurring CT scanning. Consequently the devise of low dose imaging protocol is...
Security is a vital issue in communication and storage of the images and encryption is one of the ways to ensure the security. This paper proposes an efficient image encryption scheme based on a Peter De Jong chaotic map and a RC4 stream cipher. A Peter De Jong map is employed to determine the initial keys for the RC4 stream generator and also during permutation stage. The RC4 stream generator is...
WiMAX refers to Wireless Interoperable implementations of the IEEE 802.16 standards ratified by the WiMAX Forum has a main goal to deliver wireless communications with quality of service in a secured environment. The WiMAX MAC layer is designed to support different types of applications and services having different Quality of service (QoS) requirements. In addition of providing higher throughput...
A rapid growth of digital information due to the vast development of internet and the availability of advanced digital devices has led to the huge development of digital information creating the challenges in various digital search applications in several areas such as medicine, commerce, education, and crime prevention. It is required to develop new content based search system low computational cost...
In this paper low power square and cube architectures are proposed using Vedic sutras. Low power and less area square and cube architectures uses Dwandwa yoga Duplex combination properties of Urdhva Tiryagbhyam sutra and Anurupyena sutra of Vedic mathematics. Simulation results for 8-bit square and 8-bit cube shows that proposed architectures lowers the total power consumption by 45% and area by 63%...
High speed pipelined multiplier architecture is proposed in this paper. The pipelined architecture consists of 3 stages. 1st stage consists of the 4 - bit Vedic Multiplication unit. 2nd stage consists of partial products and carry. 3rd stage consists of adders and the result of the multiplication. This paper presents the efficiency of Urdhva Triyagbhyam Vedic method for multiplication which strikes...
