in the new millennium, information technology (it) has become very effective and this is becoming evident in both developed and developing countries. these areas are especially within the fields of information gathering, in the broadest sense, and of developing and strengthening networks both internal and external to the surrounding environment. today, more and more companies, organizations and...

Communication security has become the keynote of the "e" world. Industries like eComm, eGov were built on the technology of computer networks. Those industries cannot afford security breaches. This paper presents a methodology of securing computer communication based on identifying typical communication behavior of each system user based on the dominant set of protocols utilized between the net...

Covert communication refers to the process of communicating data through a channel that is neither designed, nor intended to transfer information. Traditionally, covert channels are considered as security threats in computer systems and a great deal of attention has been given to countermeasures for covert communication schemes. The evolution of computer networks led the communication community...

We present a distributed algorithm for determining optimal concurrent communication ow in arbitrary computer networks. Our scheme is applicable to a wide range of network ow applications in computer science and operations research. As an example, it can be used for determining optimal task migration paths in metacomputing environments, or for work-load balancing in arbitrary heterogeneous compu...

Parallel computer networks are interesting topic, but they are also difficult to understand in an overall sense. The topological structure of these networks has elegant mathematical properties, and there are deep relationships between these topologies and the fundamental communication patterns of important parallel algorithms. In this paper we would like to provide a holistic understanding of p...

in vehicular ad hoc networks there is the ability to communicate between vehicles. this communication which is wireless should be rapid and reliable. these networks have unique characteristic. this communication among vehicles has many advantages in safety and comfort applications. since, the roads are always encountered to accidents and risks, using optimized tools could be useful in these sit...

In this paper we formulate the problem of routing over dynamic networks with finite doubling dimension. This is motivated by communication in mobile wireless networks, where the communication graph topology changes over time, but has some geometric properties, motivating the model for finite doubling dimension. Since wireless network bandwidth is precious, we consider communication cost require...
