In the modern era evaluation of networking and wireless networks has come in information and communication technology, there are so many things that gives facility to deal with these technology using internet. In internet email security is main aspect and the process of cryptography plays an important role to provide the security to the networks. To improve security and efficiency, most email s...

the profound changes that have occurred in information technology-communication, accompanied by a paradigm shift in technology, industrial technology, information technology has caused so much so that it may be said computer electronic networks, the infrastructure and the dynamic world are. given the widespread and profound implications for the emerging internet phenomenon in human biology and ...

Future high-speed computer communication networks are expected to utilize Asynchronous Transfer Mode (ATM) technology. In order to broadly deploy ATM-based networks, numerous congestion control mechanisms are presently being developed by the industry and research community alike. In this paper, we propose a general method to evaluate the performance of a given congestion control scheme by obser...

Computer control systems are commonly designed in such way that observations are sampled equidistantly in time (time-triggered sampling). Networked control systems (NCS) are a special class of computer controlled systems, where sensors, controllers and actuators are spatially distributed and are only able to exchange information over a digital communication network. Due to the fact that these c...

Hybrid dynamic systems are of major research interest nowadays due to their use as models in many applications in computer science and systems control. One of the major problems in hybrid dynamic systems is establishing their key property of stability, which also is important in controller design. The use of communication networks in supervisory control of distributed control systems introduces...

Social Informatics is the body of research that examines the design, uses, and consequences of information and communication technologies in ways that take into account their interaction with institutional and cultural contexts. This article serves as a brief introduction to social informatics. Examples such as computer networks, scientific communication via electronic journals, and public acce...
