In this paper, a health care system is described for rural areas considering a small village using hybrid network i.e. which operates both in ADHOC and cellular region. In this system, a small village is considered in which sensors are attached to people, the whole area is divided into clusters. The sensors considered for this system can operate in both ADHOC and GSM region. In each cluster, a sensor...
Wireless Sensor Network (WSN) having a small sensor suffers from limited computational and communication power. These sensors are deployed randomly and sparsely in the network. One of the major problems occurring in such environment at the time of deployment is the formation of holes in the network. The hole is a communication gap, which affects the general performance of the network. An improved...
This paper presents an improved design of active RF CMOS double balanced Gilbert mixer. The designed mixer adheres to the IEEE 802.15.6 standard and can be used for WBAN applications, particularly for biomedical applications. The Designed circuit has been optimized for high conversion gain, high linearity and low power consumption. RF frequency used is 2.4GHz that is ISM band. LO frequency is 2GHz...
SwachhBharat Abhiyan (English: Clean India Mission and abbreviated as SBA or SBM for “Swachh Bharat Mission”) is a national campaign by the Government of India, covers 4,023 well populous cities and towns, to keep the areas and infrastructure of the country clean. The aim of this mission is to clean and cover all the rural and urban areas of the country so that to present this country as an ideal...
Wireless sensor networks (WSNs) is an assemblage of several lightweight and portable devices, usually deployed for monitoring and surveillance purposes. On the account of their small size these sensor nodes suffer from certain limitations such as limited source of energy, constrained memory size and low processing speed. Nowadays major research areas include devising new methods to prolong the network...
Wireless Sensor Networks are a continuously explored area for sensing and monitoring tasks. Applicability of the field in almost all domains support the claim, reasons being the ability of these networks to work efficiently even in harsh environments. Instead of all nodes participating in the sensing process, a better approach is data aggregation with clustering as its direct application. Selection...
This paper presents real time issues faced in the practical implementation of the zigbee based battery status monitoring and charge sharing system. For experimental evaluation four autonomous wheeled robots or nodes were designed. All these nodes were integrated with battery status indicators, Zigbee transceiver modules and obstacle detection sensors for collision avoidance. Only two robots were fitted...
It is recommended to utilize a dynamic multithreaded OS for WSN (Wireless Sensor Network) platforms. This operating system gives a helpful threading model, for Underwater Sensor network applications. Virtual reminiscence is bolstered by means of the collaboration of the compiler, consequently that the sensor network policies is to be able to implement code bigger than the corporeal code reminiscence...
Wireless sensor networks (WSN) are being used worldwide in many areas. As the application areas of the WSN are increasing at the same rate the security threats are also increasing. Intruders are applying various mechanisms to access the sensible and confidential data from sensors. Hence, strong security measures are much needed to immune WSNs from various attacks. Authentication is a security mechanism...
