In this paper, we implement a modern serial backplane platform for telecommunication inter-rack systems. For combination high reliability and low cost protocol property, we applied high level data link control (HDLC) protocol with low voltage differential signaling (LVDS) bus for card to card communicated over backplane. HDLC protocol is a high performance with several operation modes and is fa...

Recently, Elmes, Pollett and Walker 2] proposed a deenition of a quasistationary distribution to accommodate absorbing Markov chains for which absorption occurs with probability less than 1. We will show that the probabilistic interpretation pertaining to cases where absorption is certain (van Doorn 13]) does not hold in the present context. We prove that the state probabilities at time t condi...

Wheelchairs are used by the people who cannot walk due to physiological or physical illness, injury or any disability. Recent development promises a wide scope in developing smart wheelchairs. The present article presents a gesture based wheelchair which controls the wheelchair using hand movements. The system is divided into two main units: Mems Sensor and wheelchair control. The Mems sensor, ...

We present an automata-based algorithm for checking finite state systems for hyperproperties specified in HyperLTL and HyperCTL⇤. For the alternation-free fragments of HyperLTL and HyperCTL⇤ the automaton construction allows us to leverage existing model checking technology. Along several case studies, we demonstrate that the approach enables the verification of real hardware designs for proper...

This paper presents a study about hardware attacking and clock signal vulnerability. It considers a particular type of attack on the clock signal in the I2C protocol, and proposes the design of a new sensor for detecting and defending against this type of perturbation. The analysis of the attack and the defense is validated by means of a configurable experimental platform that emulates a differ...

We present a novel holistic approach (called IC – Intra-route and Inter-route Coordination) to prolong the sensor network lifetime under the end-to-end delivery delay constraint. IC is composed of two lifetime balancing modules: (i) the IntraRoute Coordination module that allows the nodes on the same route to balance their nodal lifetimes through adjusting the MAC behaviors collaboratively; (ii...

IC and SPI are the most commonly used serial protocols for both inter-chip and intra-chip low/medium bandwidth data-transfers. This paper contrasts and compares physical implementation aspects of the two protocols through a number of recent Xilinx’s FPGA families, showing up which protocol features are responsible of substantial area overhead. This valuable information helps designers to make c...
