IEEE, Mumbai, pp. 36 - 41, 2015.[Abstract]

Currently, Indian fishermen use handheld radios or satellite phones for offshore communication. While the former is based on broadcast communication with its range limited by Line-of-Sight, the latter is expensive. Therefore, lack of connectivity-at-sea is a huge problem for many Indian fishermen. Hence, this work prescribes a hierarchical point-to-multi-point backhaul network using long range (LR) Wi-Fi technology. It is a multi-hop network consisting of base stations and clusters of boats. Each boat-cluster forms a wireless mesh access network. A field-trial was conducted at sea to measure and analyze the coverage and connectivity of the P2mP LR Wi-Fi backhaul network, using commercially available 5 GHz base stations, antennas and customer premises equipment (CPE). Several parameters such as transmission power level, mechanical antenna tilt at the base station and channel bandwidth were fine-tuned to maximize the range. This paper discusses the observations and the results obtained.

2014 Conference Proceedings M. V. Ramesh, Raj Dhanesh, and Dilraj, N., “An Assistive Device for Managing Urinary Incontinence”, Proceedings of the 6th IBM Collaborative Academia Research Exchange Conference (I-CARE) on I-CARE 2014. ACM, New York, NY, USA, pp. 1-4 , 2014.[Abstract]

Urinary Incontinence (UI) is a common and embarrassing condition affecting people of all age groups, especially women, aged population, patients with certain neurologic diseases, children born with spinal cord disorders, spinal trauma and other diseases of spinal cord, after certain pelvic and prostatic surgeries, etc., and they cause significant emotional impact on their quality of life. In this paper, we proposed a novel design of an assistive device for managing UI. We have also designed and developed a system for real time monitoring of urinary bladder and a control system for wirelessly triggering the opening and closing of an artificial sphincter by patients. One of the major requirements is on selecting a suitable electrically activated polymer that provides maximum deflection for minimum applied power. In this work we have studied and analyzed existing polymers and selected the most suitable Ionic Electro-Active Polymer (EAP) based on the results from the analysis. For continuous operation of this assistive device, one of the major challenges is to optimize the power usage. To achieve that goal, we have proposed and implemented a state transition algorithm for real-time optimization of power usage. The complete system is designed to be scalable to monitor multiple patients using one external device. Use of this device will provide an opportunity for the patients to engage in regular activities and also provide assistance and support for caretakers in old age homes and hospitals. A prototype of the complete system is developed, tested and results are described in this work.

With the recent advancements in and popularity of wireless networks, the security based issues are also increasing considerably. In this paper, we look at the data security and situational security vulnerabilities in the communication network for fishermen at sea being developed by our research center. We are proposing certain solutions and algorithms for avoiding some of the situations. They are Adaptive Contextaware Transmission Power Control (ACTPC) as a proposed solution for preventing unauthorized users at the maritime border, along with border alert and distress alert. The algorithms are implemented using a network of MICAz motes.
