A Wireless Body Area Network (WBAN) is a network of wireless sensors and medical equipments located inside or outside the human body for collecting biological signals for various medical and non-medical applications. IEEE 802.15.6 was developed as the standard for WBAN where nodes can access the channel via contention access or contention free access. In this paper, only contention access is considered. A Non-Cooperative Game theoretical framework is applied for the IEEE 802.15.6 WBAN MAC analysis. Then the game model is appropriately modified so as to improve the network throughput and data latency by defining the utility function of each node as function of these two factors. All the nodes will be trying to maximize its utility function by adopting suitable strategy. The existence of Nash equilibrium is verified for this game. Simulation shows improved performance of the proposed mechanism when the equilibrium is attained.

Resource usage of a software is an important factor to be taken into consideration while developing speaker recognition applications for mobile devices. Sometimes usage parameters are considered as important as accuracy of such systems. In this work, we analyze resource utilization in terms of power consumption, memory and space requirements of three standard speaker recognition techniques, viz. GMM-UBM framework, Joint Factor Analysis and i-vectors. Experiments are performed on the MIT MDSVC corpus using the Energy Measurement Library (EML). It is found that though i-vector approach requires more storage space, it is superior to the other two approaches in terms of memory and power consumption, which are critical factors for evaluating software performance in resource constrained mobile devices.

In this paper, we have demonstrated the feasibility of hardware implementation of 2-hop free space optical communication link. Modeling of the fading has been done with the use of modified optical chopper. This paper shows that the use of multi-hop communication system guarantees the BER performance system over direct link. Placing the relay node at different locations between transmitter and receiver also provides various results out of which the best results can be achieved when the chopper is placed at the mid of the link.

Independent of the application field, major factors in focus when using the products are quality, cost and time. Empirical studies have shown that in IC design projects as much as half of the projected schedule is spent on the verification activities. Our research work involved exploring the current state of practice of the verification process, investigating methods for achieving efficient fault detection during the product verification, implementation of accumulated knowledge and techniques for efficient verification in one real-world practical case and analysing the impact of the current verification process in terms of time, cost and quality of product verification. This paper covers the views of verification experts in semiconductor industry on latest verification techniques. It shows the most commonly used verification improvement activities that had been implemented by semiconductor companies and its impact on quality, cost and time of the products. The methodology encompassed survey and semi-structured interviews at VLSI companies. Experiments were done to evaluate the new verification methods before using them in real projects. This paper is mainly focussed on identifying the gaps between the expectation of the verification experts and their real experiences of latest verification techniques for product verification process in semiconductor industry.

Due to rise in vehicular traffic, the existing parking systems are inadequate and are unable to handle the parking loads in major urban centers and cities. Therefore, there is a need and continuous demand of computerized, highly precise, and real time parking device for any city. The existing systems have complex process and have drawbacks in terms of vehicle sensor located in parking lots. Hence, to address this gap, the Radio Frequency (RF) global positioning system for real time vehicle parking has been designed in compliance with IEEE 802.15.4 standards as one of the ways to address the vehicular parking problem. The wireless sensor based position detection and display module is implemented successfully. The developed position detection module is capable of the integration to any vehicle. This system implementation is based on Received Signal Strength (RSS) values and the channelization techniques. The mean-mode model is used to enhance the results of received signal strength in position measurement and the channelization is used for vehicle identification. This system is useful for crowded vehicle (car) parking with improving position detection, and direction.

This paper presents the physical implementation of an antenna system for 4-by-4 MIMO communication. Considering the size of the typical antenna for LTE-band wireless communication, it is very difficult to increase the number of the radiators more than two and integrate them in a limited volume of the smart phone. To circumvent this difficulty, compact radiators are designed based on the zeroth-order effect and placed in their vicinity. At the same time, these antenna elements are decoupled through the trapping structure for a high isolation. Further, a pair of chip antennas is developed and put together with the zeroth-order antennas, while all the radiating elements have good isolation performances, which is one of the key-factors to the MIMO system.

This paper investigates the problem of distributed joint channel and power allocation using game theoretic learning solutions in an underlay Device-to-Device (D2D) network where device pairs communicate directly with each other by reusing the spectrum that is being used by cellular users. This reuse, in addition to increasing the capacity, results in new cross-tier and co-tier interference cases. In order to garner the advantages of the resource reuse in the form of higher bit rates and increased energy efficiency, efficient and scalable resource allocation schemes are required. In the next generation ultra-dense networks, the focus is on distributed solutions with low computational complexity and signaling requirements. We formulate the joint channel and power allocation problem as a multi-agent learning problem with discrete strategy sets and suggest a fully distributed learning algorithm to determine the channel index and power level to be used by each device pair. The distributed joint channel and power allocation problem is formulated as an interference mitigation game, where the utility of each player is a function of its experienced expected weighted interference. We then propose a completely distributed and uncoupled stochastic learning algorithm which converges to pure strategy NE in a time-varying radio environment.
