A Review: Clumping in Mobile Adhoc Networks

ABSTRACT: Mobile ad hoc networks (MANETs) consist of mobile devices that form the wireless networks without any fixed infrastructure or centralized administration. The infrastructure based cellular architecture sets up base stations to support the node mobility. Mapping the concepts of base stations into MANET leads to the design of logical clump, where the clump heads in every clump play the role of base station. Clumping in MANET is the virtual partitioning of the dynamic nodes into various groups. In this paper, we have proposed protocols and algorithms for efficient design of clumping in MANET. Closer Clump Detection Protocol (CCDP) has been designed to help the nodes to probe their immediate neighbours. Energy Based Clumping Algorithm (EBCA) has been proposed that uses the node mobility and its available battery power for calculating the node weights. A Broadcasting Range Adjustment Protocol (BRAP) has been proposed which allows the isolated nodes to adjust their ranges to remain connected with existing clump heads. Each of the work is evaluated separately to analyse their performances and compared with the competent results

A Review: Wireless Body Area Networks for Health Care

ABSTRACT: In wireless body area networks various sensors are attached on clothing or on the body or even implanted under the skin. The wireless nature of the network and the wide variety of sensors offer numerous new, practical and innovative applications to improve health care and the Quality of Life. Using a WBAN, the patient experiences a greater physical mobility and is no longer compelled to stay in the hospital. In this paper, we present an overview of wireless body area network and we also provide the differences between Wireless Body Area Network and Wireless Sensor Network (WSN) that is inadequate to apply in WBAN. We also present an idea to improve healthcare systems in India with the help of telecommunication and information technology by using wearable and implantable body sensor nodes which does not affect the mobility of the patients. We discuss how the wireless body area networks are used for healthcare monitoring by using multiple sensor nodes. In this paper we present various innovations and discuss promising new trends of wireless body area networks for ubiquitous health monitoring applications

Performance Analysis of Energy Efficient Grid based Wireless Body Area Network System

Wireless Body Area Network makes it possible to monitor patient2019;s health under critical situations by integrating bio-sensors with a mobile phone. With this WBAN has now become a emerging technology to improve patient2019;s quality of life by enabling health monitoring at home instead of at a hospital. WBAN reduces the workload of medical practitioners as well as healthcare costs which further results in higher efficiency. This paper presents the architecture of existing wireless health monitoring system (WBAN system). Due to limited battery capacity of sensor nodes there is need to have energy efficient design. This work explores the grid based data dissemination model for WBAN. The grid model divides the network area into cells. All the nodes will not participate in data transmission which conserves energy. Further we compare existing model with the grid model on the basis of energy consumed, throughput and delay
