In this paper, we consider the application of network coding(NC) for network management system of Radio and Television Broadcasting Stations in wireless network using a narrow band radios modem &Routers ) as a means of transmission to communicate between the loins broadcast TV/FM stations . Our main contribution is the application of NCimproved by the proposed an effective strategy,called Fast ...

"Risk communications" has acquired some importance in the wake of our experience of SARS. Handled well, it helps to build mutual respect between a government or an organisation and the target groups with which it is communicating. It helps nurture public trust and confidence in getting over the crisis. The World Health Organization (WHO) has also come to recognise its importance after SARS and ...

Today’s universal communications increasingly involve mobile and battery-powered devices (e.g. hand-held, laptop) over wired and wireless networks. Energy efficiency, as well as throughput, are becoming service characteristics of dominant importance in communication protocols. Although standard TCP versions lack the functionality to efficiently adjust their error-control strategies to distinct ...

After Vietnam’s Declaration of Independence on 2 September 1945, the country had to suffer through two long, brutal wars, first against the French and then against the Americans, before finally in 1975 becoming a unified country free of colonial domination. Our purpose is to examine the role of cryptography in those two wars. Despite the far greater technological resources of their opponents, t...

We investigate autonomous opportunistic spectrum access (OSA) strategies for a distributed CR network, where two or more distributed CRs sense the channels sequentially in some sensing order until they find a free channel to transmit on, if one exists. First, we evaluate the performance of a traditional OSA strategy in terms of probability of success (probability that a given cognitive radio fi...

In practical speech recognition applications, channel/environment conditions may not match those of the corpus used to estimate the acoustic models. A straightforward methodology is proposed in this paper by which the speech recognizer can match the acoustic conditions of input utterances, thus allowing instantaneous adaptation schemes. First a number of clusters is determined in the training m...

civil liability in electronic communications is one the most important issues of information and communications technology (ict) law. civil liability may be arisen from different causes such as copyright and trade mark infringement invasion of privacy and defamation. when discussing civil liability, two different civil liability systems may be considered: direct and indirect civil liability. in...

The concept of strategic communications rose to prominence especially with the events linked Crimea annexation and Russian intervention in Eastern Ukraine. As such it has been mostly related reactive fight against disinformation propaganda or other elements hybrid campaign. This paper aims point much broader potential for tool support goals realm national security defence, while is understood a...

with the advent of digitalization, information and communications technology facilities have become an indispensable part of education especially at the universities. this study has been undertaken with dual purposes - to find the existing scenario of information and communications technology facilities and to gauge the perception of the students onthe quality of those facilities - at the unive...

On our crowded roads, drivers must compete for space but cooperate to avoid occupying the same space at the same time. Decision-making is strategic and requires mutual understanding of other’s choices. Fully autonomous vehicles (AVs) will need risk management software to make these types strategic decisions without human arbitration. Accidents will occur, and what constitutes rational and ‘safe...
