This paper is concerned with the consensus tracking problem of high order MIMO nonlinear multi-agent systems. The agents must follow a leader node in presence of unknown dynamics and uncertain external disturbances. The communication network topology of agents is assumed to be a fixed undirected graph. A distributed adaptive control method is proposed to solve the consensus problem utilizing re...

Vehicular ad-hoc network (VANET) is an important component of intelligent transportation systems, in which vehicles are equipped with on-board computing and communication devices which enable vehicle-to-vehicle communication. Consequently, with regard to larger communication due to the greater number of vehicles, stability of connectivity would be a challenging problem. Clustering technique as ...

We have long assumed that being face to face is the best environment for social interaction. But is "being there" the best we can aspire to? One common approach to improving face-to-face contexts is to add new communication channels — a strategy often described as creating "backchannels." In my work, I use a series of novel complementary communication systems to show how adding communication pl...

The potentialities of chaos to secure transmitted messages in digital communications has been proved. This by use Direct Sequence Code Division Multiple Access (DSCDMA) system using chaotic spreading sequences. Two synchronization methods for Chua’s digital chaotic generator, are presented: the master-slave synchronization and the impulsive synchronization. In the first method, the driving sign...

Abstract In this paper we present optical communication multibus system including: physical topology, logical topology, structure of central control unit (CCU). We describe the task of CCU: analyze the state of logical buses, topology reconfiguration, system structures clustering, unexpected events handling, statistic gathering, etc. In this paper we present synthesis of core system network bas...

Forty years after AT&T’s Picturephone, video is still mainly considered as a way to enhance audio communication in an attempt to reproduce face-to-face conditions. In a 1992 paper, Hollan and Stornetta argued that we should develop communication tools that go beyond being there. In this paper, I discuss two different interpretations of their analysis. I then propose the concept of multiscale co...

Organizations today adopt and implement new technology e.g. information and communication systems for different reasons. The new technology affects the organization structure in different ways and every employee who works and participates in the organizational tasks is affected. In organizations where the employee does not have the technology as a work tool it could be difficult to reach the pu...

As a subscriber becomes more aware of the mobile phone technology, he/she will seek for an appropriate package all together, including all the advanced features of a cellular phone can have. Hence, the search for new technology is always the main intention of the prime cell phone giants to out innovate their competitors. In addition, the main purpose of the fifth generation wireless networks (5...
