Orthogonal Frequency Division Multiplexing (OFDM) has become a popular modulation method in high speed wireless communications. By partitioning a wideband fading channel into flat narrowband channels, OFDM is able to mitigate the detrimental effects of multipath fading using a simple one-tap equalizer. There is a growing need to quickly transmit information(More)
We present a possible observing scenario for the Advanced LIGO and Advanced Virgo gravitational-wave detectors over the next decade, with the intention of providing information to the astronomy community to facilitate planning for multi-messenger astronomy with gravitational waves. We determine the expected sensitivity of the network to transient(More)
We discuss the idea of differential fairness in polling systems. One such example scenario is: primary customers demand certain Quality of Service (QoS) and the idea is to utilize the surplus server capacity to serve a secondary class of customers. We use achievable region approach for this. Towards this, we consider a two queue polling system and study its(More)
In air crafts, missiles and ships, during their motion, the sensors are prone to undergo lot of vibrations and shocks. Because of their sensitivity to these environments they malfunction. In order to avoid this situation all the sensors are modelled and analysed at the ground for different parameters viz. temperature, vibration and shock etc. A Ring Laser(More)
Many device to device communication networks can be modelled by multi-class tandem queues. In many applications, it is desired to have different quality of service for various classes. This can be achieved by implementing dynamic priority across classes. Performance analysis is an important aspect in such multi-class tandem queueing models for resource(More)
Small cell networks promise to boost the capacity and provide good QoS (Quality of Service) to cell edge users. However they pose serious challenges, especially in the case of high speed unidirectional (e.g., users traveling on highways or in metros) users, in the form of frequent handovers. The extent of the handover losses depend greatly upon the speed of(More)
Completeness of some scheduling policies with mean waiting time performance measure is used quiet extensively in literature for dynamic control of multi-class queues due to its wide range of applications in computers, communication networks and manufacturing systems. For a single class queue, we introduce the idea of 2-moment completeness of a parametrized(More)
Conservation laws and the related achievable region for mean waiting times are important concepts in multi-class queues. The nice geometric polytope structure of this region driven by the conservation law is exploited extensively for dynamic control of multi-class queues. Such control problems have wide range of applications in computers, communication(More)
