Access to healthcare is extremely poor in almost every region within India due to a variety of factors including large populations, substantially low presence of health care experts, lack of medical resources and economic constraints. The situation is further worse in rural areas where access to doctors is largely absent. In this vision paper, we present a new scalable mobile tele-consultation model for significantly enhancing access to healthcare for patients in both urban and rural settings. Given the scarcity in the availability of doctors, our mobile consultation model can enhance the efficiency of the healthcare delivery system by allowing doctors to cover a much larger patient base within a limited time frame. Our tele-consultation system can also be tailored for a variety of common health conditions including basic health care queries, infectious diseases, HIV, diarrhea, virology and specialized health problems such as maternal care, child care, geriatric care, ophthalmology, cardiac issues etc. In this paper, we specifically describe how our tele-consultation framework can be applied to enhance care for the most pressing health problems in India.

Natural Disaster occurs without prior intimation and often come along with the destruction of the local telecommunication infrastructure causing severe problems for rescue operations. Emergency Telecommunication restoration systems (ETRS) play an ever-increasing and important role in ensuring timely and effective response to emergency. The promptness of action in the rescue phase can save many lives during and after disaster. Satellite communications plays an important role in the ETRS. We have explored GSM over satellite technology as an effective ETRS. An ETRS is effective if the communication restoration is over existing user terminals and hence GSM is chosen. This paper emphasizes on GSM protocol architecture over satellite medium and describes the implementation details of an Emergency GSM Satellite portable terminal. We have analytically evaluated the performance of the proposed GSM satellite portable terminal as an effective ETRS. The results clearly bring out elevated features of the proposed system.

Storage Warehouse managers face diverse challenges in operating and managing a warehouse. Problems range from capacity-planning and inventory management of stored goods, loss or damage of stored goods due to weather changes, pest infestation and improper handling, to infrastructure issues arising from damage to physical components, such as buildings, storage components, and so on. In this paper we propose an integrated framework for warehouse management using wireless sensor networks and decision support systems. The framework takes inputs endogenously, from different warehouses using wireless sensors, and exogenously from different information systems, and routes them to a central decision support system. The central decision support system takes globally optimal decisions and produces actionable solutions to minimize cost/losses.

The analytical expression for the MGF (Moment Generating Function) of the channel capacity in log-normal fading environment is derived. Using MGF, the closed form expression for higher order moments of channel capacity are computed as a rapidly convergent infinite series. Explicit expression for error and its upper bound resulting on account of truncation of series are obtained. Numerical results based on truncated infinite series are found to be in excellent agreement with those based on Monte Carlo simulation and Gauss Hermite method. Statistical measures like coefficient of variation, skewness and kurtosis are obtained for different values of shadowing level over a range of practical interest. It is found on the basis of skewness and kurtosis that gaussian approximation for channel capacity in log-normal fading environment is not in general valid over the entire range of dBspread.

Recently, wireless body area network (WBAN) plays an important role in remote cardiac patient monitoring, and mobile healthcare applications. Generally, the use of WBAN technology is restricted by size, power consumption, transmission capacity (bandwidth), and computational loads. In this paper, we therefore propose an automated cardiac event change detection for continuous remote patient monitoring devices. The proposed event change detection algorithm consists of two stages: i) ECG beat extraction; and ii) ECG beat similarity measure. In the first stage, the onset of each QRS complex is identified using the Gaussian derivative based QRS detector and the two heuristics rules. In the second stage, we employ the weighted wavelet distance (WWD) metric for finding the similarity between two ECG beats in wavelet domain. The WWD is the weighted normalized Euclidean wavelet distance between the wavelet subband coefficients vectors of the current and past ECG beats, where weights are equal to the relative wavelet subband energies of the corresponding subbands. The experimental results show that the weighted wavelet distance measure works substantially better than the conventional PRD and the wavelet based weighted PRD (WWPRD) measures under noisy environments. The proposed approach has been tested and yielded an accuracy of 99.76% on MIT-BIH Arrhythmia Database.

Presently, the urgency of creating efficient system to tackle natural hazards such as tsunamis, earthquakes, landslides and floods to cite just a few, have originated that Wireless Sensor Networks (WSNs) play an increasingly important role in the natural hazards scenario as an efficient early warning system, sometimes in synergy with satellites---GMES (Global Monitoring Earth Systems) and also with mobile robotics. Their integration into the web scenario, giving rise to the sensor-web technology, provides even more power to the intrinsic strengths of WSNs. The WSNs application in post-disaster scenarios is also an emerging challenging issue. In this paper the fundamental technology concepts of WSNs are sketched; their application to some important natural hazards as earthquakes, landslides and tsunamis are described and relevant projects in these fields are reported. Also, some comments on the potential of the synergy of mobile robotics with WSNs are included.

Air pollution has been the bane of society for which we still have not got a satisfying solution. The air pollution due to automobiles constitutes around 60--90% of the total air pollution in the urban area. To curtail this, the mass transportation, bus facilities in particular, in any city has to be fine tuned in such a way that they serve the need of the people. In order to make the whole bus transportation easy and convenient for the public there is a need for optimizing the bus routes based on the destinations of the commuting passengers. In this paper, a demand responsive public transportation scheme is proposed, that also entitles the buses to run without a fixed schedule and adjust the schedules based on the passengers' convenience. On a given map, select places called as the "hot-spots" would serve as the present day bus stop equivalents. These hot-spots will have an appropriate hardware interface for the commuters. Upon suitable activation the passenger is making a request for the bus. This request is sent to a centralized scheduling server which will receive all such requests from various hot-spots, processes them and re-route the nearest bus to the passenger's location. Based on the passenger's destination, a route based on Djiktra's algorithm for least time of transit is generated. The communication between the server and the clients can be achieved though various technologies like GSM, Ethernet or a Wi-Fi enabled network set up. The signal that is sent from the clients to the server will again depend on the chosen network. This will enable the passengers to commute to their destination within a shorter time and in the shortest route possible.

The aim of this paper is to develop a protocol for, future SAR measurement from multiple towers. From the current knowledge base available, we have proposed procedures for the measurement of SAR and Variation depending on a number of factors like distance from the tower, number of tower in the vicinity, age, etc. This paper describes the effect of the field distribution stemming from multiple transmit antennas on a single handset. The purpose of the experiment is to analyze the SAR effect from multiple transmit antennas on one single board.
