Background/Objectives: This paper proposes efficient disaster detection and alerting system to reduce losses due to the occurrence of natural disasters worldwide. Wireless Sensor Networks (WSN) helps in disaster management to reduce the mass destruction and huge loss due to climatic change by determining the amount of disaster occurred in a particular location. Based on the physical parameters measured by the sensors, appropriate remedial actions can be taken. Methods/ Statistical Analysis: In this paper, the utilization of the Heterogeneous Sensor Networks for Disaster Management (DM) is analyzed. Also, this paper reviews the types of disasters and the different sensors utilized for measuring their intensity. Heterogeneous clustering protocol is suggested for disaster management using wireless sensor networks. Moreover, utilizing heterogeneous clustering protocol increases the life time of the power constrained sensor node. Different types of Heterogeneous clustering protocols viz. SEP, DEEC, EDEEC, BEENISH are analyzed. Findings: Among these protocols, EDEEC and BEENISH protocols show better results when the number of parameters are increased. EDEEC protocol can be applied in the analysis of earthquake, storm and volcano and BEENISH protocol can be applied in the analysis of Tsunami. Application/Improvements: For disaster prone regions, these types of clustering protocols can be utilized efficiently in order to avoid huge loss for the society as well as for the human beings.Keywords

Background: The silver nanoparticles (AgNPs) have a significant range of application in the field of biomedical technology. This can be subjected in agriculture by biological synthesis method using microbes which may inhibit disease-causing pathogens in agriculture, typically it confused on management of pathogens.
Materials and Method: In this present investigation, Rhizobium sp. was isolated from cultivable soil sample for the synthesis of AgNPs. The synthesized silver nanoparticles were characterized using UVVisible spectroscopy, Scanning electron microscopy shows regular circular shape of AgNPs followed by energy dispersive X-ray (EDX) spectrometers confirms the presences of elemental composition of materials. Transmission electron microscopy was done for the structural analysis and the surface study of synthesized AgNPs was studies by Atomic forced microscopy.
Results: The surface plasmon resonances at 425 nm confirm the AgNPs formation and morphology of the nanoparticles are polydispersed with 25-70 nm in size confirmed by the microscopic techniques. The synthesized silver nanoparticles were examined against disease-causing fungal pathogens such as Aspergillus niger, Candida albicans, and Aspergillus fumigatus in which Candida Albicans showed a maximum zone of inhibition of 15 mm at 75 μL of AgNPs.
Conclusion: Finally, the silver nanoparticles were used to perform free radicals scavenging activity.
