In this paper we present a wireless wearable body area system for locating, tracking and monitoring emergency responders in harsh and remote environments. Tracking an emergency responder and monitoring their vital signs using various medical sensors is important in supporting the safety of the emergency responder. This work is the preliminary step...

According to World Health Organization, worldwide, every year, more than 12 million people are killed in accidents and more than 500 million people are injured. In this research work, we have designed a context aware wireless sensor system to detect and locate road accidents in real-time. Context acquisition is performed using onboard sensors such...

This paper presents a remote triggered wireless sensor network (WSN) testbed used to facilitate multi-user remote access to the WSN experiments for virtual learning of wireless sensor network concepts. This testbed provides multiset, multi-group of WSN experimental setup that is capable to provide opportunity to perform remote code editing using ov...

Over the past decade, experimentation for wireless sensor network (WSN) has been widely used to enrich the learning experience of educators and learners. Our remote triggered WSN laboratory is a multi-set, multi-group, WSN experimental setup that provides an intuitive web-based interface to carry out remote experimentation as well as code editing b...

Context-aware computing enriches the capabilities of intelligent devices complemented with smart applications and helps establish smart ecosystems in fields such as Ambient Intelligence, Internet of Things, Mobile Computing, and Pervasive and Ubiquitous Computing. Though the literature has many surveys that outline existing systems, it still remain...

Water distribution systems are one of the critical infrastructures and major assets of the water utility in a nation. The infrastructure of the distribution systems consists of resources, treatment plants, reservoirs, distribution lines, and consumers. A sustainable water distribution network management has to take care of accessibility, quality, q...

Present-day devices are becoming increasingly smarter than their predecessors. From a simple passive light switch to an intelligent wristwatch, great strides have been made in networking smart devices, creating an autonomous ecosystem, the so-called Internet of Things. In an increasingly information-driven world, context-awareness supports the inte...

The Internet of Things is envisioned to provide connectivity and communication between various devices all over the world. Based on the devices and applications involved, the nature of the network formed differs. Thus, an intelligent and holistic ecosystem needs to be created wherein clients, data sources, smart objects, and services can all co-exi...

There is an explosive growth in e-Learning platforms, jointly developed by multiple institutions, which provide for virtual learning content. However, many are inadequate to support the complex requirements for collaborative development of distributed learning such as accommodation of wide-ranging technologies, servers, and remote equipment control...

Increasing dependence on groundwater as a reliable source of water in the rural areas has resulted in its indiscriminate extraction without considering the recharging capabilities of the aquifers as well as other environmental factors. As the availability of groundwater is highly inconsistent and exhibits substantial variations across the country,...

Wireless sensor networks (WSN) are small or tiny devices that consists of different sensors to sense physical parameters like air pressure, temperature, vibrations, movement etc., process these data and sends it to the central data center to take decisions. The WSN domain, has wide range of applications such as monitoring and detecting natural haza...

Spam attack is the deliberate delivery of unsolicited or unwanted messages across the computer networks with the intention to deplete the resources that results in Denial of Service (DoS) to the end user. This is more important to consider in Wireless sensor networks test beds where the nodes already have only little computing resources (4kb RAM),...

Tunnels are considered as the oldest method of passageway. Underground tunnels are popular from olden eras for connecting places, travelling, and aid for various surface threats. They are also used for illegal activities like smuggling of unlicensed drugs, weapons, currency, gold, explosives, and even human trafficking is being done through these t...

Our AMRITA remote triggered lab (RT Lab) for wireless sensor networks (WSN) offer the students and researchers, an easy, efficient, interactive and user friendly environment to trigger their inquisitiveness by providing them with the sensors, equipments, hardwares and study materials for conducting the lab experiments. RT Lab offers a web-based e-l...

Cognitive Radio (CR) is one of the most transformative innovation recently emerged in the field of Wireless Networks. CR is famous due to the limited electromagnetic spectrum and the fixed spectrum assignment policy. CR technology helps to solve the spectrum scarcity problem by using its intelligent radio which senses and adapts to the environment....

Smartphone usage has reached its peak. There has been a tremendous growth in the number of people migrating from PCs to smart phones. Numerous scenarios such as loss of a phone, phone theft etc., can lead to unauthorized use of one’s own smartphone. This raises the concern for securing personal and private data. This project proposes a light weight...

Driving at night causes approximately 50% of traffic fatalities; one of the primary causes being the usage of headlights on high beam. Courteous drivers usually lower their headlights from high to low beam when they see oncoming traffic. However, due to driver inertia, either inherent and/or caused by frequent switching between high and low beams,...

In this paper, we present a real time remote triggered laboratory which has multi-set, multi-group of wireless sensor network experimental setup which is envisioned to provide a practical experience of designing and implementing wireless sensor networks' algorithms in both indoor and outdoor conditions. The architecture provides a remote code editi...

Jamming-based denial of service attacks are a real threat in wireless sensor networks. This paper studies and analyzes the impact of jamming on micaz motes running TinyOS and explores ways to mitigate the impact. Jamming is facilitated by disabling carrier sensing on the jammer nodes. Jamming attack is detected by tracking RSSI and PDR at the recei...

When a disaster occurs, activities like search, rescue, recovery, and cleanup are carried out by emergency responders.
