The ever increasing demand for high bandwidth, low latency multimedia applications on mobile devices is set to pose a considerable challenge on the bandwidth allocation and multiplexing mechanisms in LTE and future wireless networks. One of the most important factors that diminish the quality of viewing experience of delivered videos is frequent client side rebuffering events. This paper proposes a buffer-aware downlink scheduling framework (called BA-TLS) for streaming video applications. The problem of scheduling a set of video streams over LTE has first been formulated as an Integer Linear Programming (ILP) problem. It has been shown that a conventional dynamic programming solution for the ILP imposes prohibitive online overheads. Then, by utilizing analytical properties of the problem, a genetic algorithm based fast and efficient radio resource allocation heuristic has been implemented over the proposed framework. Experimental results reveal that the developed framework is able to provide significant reductions in rebuffering events and thus allow video transmission with high and acceptable quality of service.

State estimation is essential in monitoring any Cyber-Physical System. When there is a wireless communication channel present between sensor and remote estimator, the imperfections associated with wireless channel like packet loss and quantization error due to limited capacity of the channel will have major impact on estimation. Hence, studying the effect of these imperfections is very important for critical cyber-physical system applications. In this paper, we model and study the effect of quantization and the joint effect of both packet loss and quantization on the estimation and give error covariance bounds.

This paper discusses the problem of adaptively suppressing co-channel interference in a cellular wireless receiver. The technique makes use of statistical data to design a polynomial based classifier which can be used to identify the number of co-channel interferers. The result of detection is used to adaptively vary the order of interference suppression filter and the length of overall channel impulse response. The polynomial classifier is based on the eigenvalues of error covariance matrix and signal-to-interference-plus-noise ratio (SINR). An improvement of 1.5 dB is seen in receiver performance. Further, the parameters so derived for the classifier can be used to enhance the reliability of channel state information in more advanced communication systems, preferably LTE-A or 5G.

A smart factory requires an efficient interaction between a number of physical components on the factory floor with the respective analytical and decision making components from digital domain. The flow of this information has to be continuous in order to reduce the downtime and maintain the productivity target. A smart factory should provide immediate access to the status of processes and device components to the relevant factory operators. With advancement in the concept of internet of things (IoT), many industrial devices on the factory floor now have wireless connectivity. Bluetooth technology is increasingly being used in order to provide operational and productivity status of devices to the factory floor operator. The operator typically has a smart device such as a tablet from where the respective devices can be monitored or controlled. As Bluetooth has a limited range, typically around 5–10 meters, an operator needs to come within this range of the device in order to connect with the respective industrial device and obtain its health and operational status data. Also Bluetooth mainly provides a point-to-point connectivity, thus at a time only one industrial device can be connected. For a factory floor that can have hundreds and thousands of such devices, this task of personally going and obtaining the data from every individual device could be tedious and cumbersome.

A tighter coupling [1] between LTE and Wi-Fi interfaces can be achieved by integrating them at the radio protocol stack. LTE Wi-Fi radio level integration with IPsec tunnel (LWIP) is one such architecture introduced in Rel.13 of 3GPP. We have developed a variant of LWIP prototype and made commercial UE to readily work with the LWIP. The developed LWIP testbed uses OpenAirInterface (OAI) for LTE network and Cisco AP /Atheros device with Hostapd as Wi-Fi Access Point. In this demo, we present the aggregation benefits of using LWIP at flow/packet/bearer level steering across LTE and Wi-Fi links.

Detection of landmarks in mobile sink environment which is generally used to improve the network lifetime is an important problem in WSN. In this paper, a method is proposed to trace the landmarks in a network leading to energy-efficient networks. The algorithm for clustering and landmarks tracing proposed herein uses the concept of random walks on graphs. The proposed method comprises of two phases namely, flow escalation and flow control and it does not require location information of the nodes. Additionally, prior information about number of optimal clusters is also not required. Experimental simulations illustrate the process of landmark detection along with clustering. Results obtained from analysis of WSN lifetime and number of data packets transmitted are motivating.

PorFloR™ is a point-of-care portable fluorescence reader. It is a small handheld device that records the intensity of fluorescence spot and change in fluorescence intensity of the spot on the solid 2D base (e.g. paper strips) material. Nowadays, numerous fluorescence based lateral flow immunoassay (LFIA) techniques are utilized for the detection of various disease biomarkers. Most of the techniques depend on visible colorimetric detection process. Results obtained from such techniques are qualitative or semi-quantitative. Thus, we have developed the portable, easy-to-use, low cost, point-of-care strip reader that can detect the appearance as well as change in fluorescence intensity on the surface with quantitative precision. The output from device can be programmed to display the presence as well as concentration of an analyte.

Rash driving is one of the primary reasons for road fatalities. However, the existing literature seldom talks about precise quantitative measures to assess behaviors like rash driving during traffic analytics. Moreover, the subjective factors like broken road patches, high peak bumps (or some time known as speed breakers in some countries), poor night illumination etc. have not been taken into consideration in the existing driver rating systems. This paper develops a methodology for fair and effective driver rating using a dynamic time warp (DTW) method, based on their behavioral observations as captured by smartphone sensors (GPS, accelerometer, light sensor etc.). The value of the correlation coefficient between the system rating and a manual rating is found to be more than 70% for our proposed system, SafeDrive, when tested extensively for bumps along a 7km city road patch. The system can be extended to provide a comprehensive driving score by including other road features like pot holes, sharp turns etc., in addition to bumps.

We address the problem of security of cyber-physical systems where some sensors may be malicious. We consider a multiple-input, multiple-output stochastic linear dynamical system controlled over a network of communication and computational nodes which contains (i) a controller that computes the inputs to be applied to the physical plant, (ii) actuators that apply these inputs to the plant, and (iii) sensors which measure the outputs of the plant. Some of these sensors, however, may be malicious. The malicious sensors do not report the true measurements to the controller. Rather, they report false measurements that they fabricate, possibly strategically, so as to achieve any objective that they may have, such as destabilizing the closed-loop system or increasing its running cost. Recently, it was shown that under certain conditions, an approach of “dynamic watermarking” can secure such a stochastic linear dynamical system in the sense that either the presence of malicious sensors in the system is detected, or the malicious sensors are constrained to adding a distortion that can only be of zero power to the noise already entering the system. The first contribution of this paper is to generalize this result to partially observed MIMO systems with both process and observation noises, a model which encompasses some of the previous models for which dynamic watermarking was established to guarantee security. This result, similar to the prior ones, is shown to hold when the controller subjects the reported sequence of measurements to two particular tests of veracity. The second contribution of this paper is in showing, via counterexamples, that both of these tests are needed in order to secure the control system in the sense that if any one of these two tests of sensor veracity is dropped, then the above guarantee does not hold. The proposed approach has several potential applications, including in smart grids, automated transportation, and process control.

Dedicated Short Range Communication is attracting a lot of interest these days due to its utility in vehicular safety applications, intelligent transportation system and infotainment applications. Such vehicular networks are characterized by the highly dynamic changes in topology, no significant power constraints and ephemeral links. Considering an interaction between the client and server nodes that last for a random duration of time, an important question is to maximize the amount of useful content downloaded by the client, either in a single request phase, or iteratively in multiple phases. The aim of this work is to propose and investigate a multiphase request model using Markov Decision Process and compare its efficiency against a single phase version. We show that a multiphase request protocol performs better than single phase protocol.
