The challenge raised by the introduction of Internet of Things (IoT) concept will permanently shape the networking and communications landscape and will therefore have a significant social impact. The ongoing IoT research activities are directed towards the definition and design of open architectures and standards, but there are still many issues requiring a global consensus before the final deployment...
This paper presents an analysis of new Dual Crosspoint Queued (DCQ) crossbar switch architecture. It is well-known that in order to achieve performance guarantees, the priority separation of incoming traffic is necessary. Therefore, we modified CQ crossbar switch with the separation of different traffic flows, by implementing two buffers in each crosspoint of switch fabric. Different round robin based...
New frequency hopping synchronization scheme based on real-time clock is proposed. Flow diagram of the synchronization process is presented. As performance measures of the scheme we use probability of false synchronization start and probability of synchronization. Expressions for both performance measures are derived and numerical results are presented. Simulation results in radio channel with high...
The true random binary sequence generator provides a secure, non-reproducible source of true random binary sequences for applications with strong security requirements, such as for generating encryption keys and for secure communications. In this paper we present a realization of true random binary sequence generator. Thermal noise found in chaotic physical system is used as a source of true randomness...
This paper presents a realization of digital correlator based on FIFO (First In First Out) buffer with significantly reduced hardware compared to previous hardware realization of PN (pseudonoise) correlator. The operation principle of proposed digital correlator is described. It is followed by the hardware solution for multichannel (multiple) programmable digital correlator which allows simultaneous...
