    HIERARCHICAL ROUTING PROTOCOL IN WIRELESS SENSOR NETWORK
    (PSGR Krishnammal College for Women, 2015-01-29) K, Geethalakshmi; R, Divya
    A wireless sensor network consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location. In the wireless sensor networks, routing protocols and data aggregation schemes are used to reduce the large amount of transmissions. In the wireless sensor network, security is an important concern. However, the characteristics of wireless sensor networks require more effective methods for data forwarding and processing. In WSN, the sensor nodes have a limited transmission range, and their processing and storage capabilities as well as their energy resources are also limited. Routing protocols for wireless sensor networks are responsible for maintaining the routes in the network and have to ensure reliable multi-hop communication under these conditions. In this paper, we give a survey of routing protocols for Wireless Sensor Network and compare their strengths and limitations.

    MOLECULAR IDENTIFICATION OF GRAM -VE PATHOGEN AND SEQUENCE ANALYSIS
    (Center for BioScience and Nanoscience Research, 2019-08-31) K, Geethalakshmi; K, Aishwarya Dharshini
    This document gives a clear view of the molecular identification of the various pathogens present in the diabetic foot(wound).This identification of the pathogens can be used to know the multi drug resistance using various anti-biotic disks. Every pathogen or the bacteria is prone to certain anti-biotic and is useful to know which anti-biotic can be used to treat the wounds. Also the pathogens are put to the process of DNA Isolation. It undergoes a PCR amplification stage where many million copies of a DNA is made in an exponential way using thermo-cycling. The gene sequencing is done to figure out the order of DNA nucleotides or bases in the genome.
