This paper introduces analysis of landslide detection based on wireless sensor network and GSM. And also here we introduce some other methods used for detection of landslide. We are also trying to give short information about our proposed method which is implanting next paper. This paper presents an independent landslide monitoring system based on wireless sensor networks and GSM. Provides real time measurement of various constraints such as amount of rainfall, moisture, and movement of land when trees and rocks are about to fell and also drive of the land as landslide occurs due to the earthquake are read by the microcontroller. The planet Earth has hundreds of impact events, with some occurrences causing both in terms of human casualty as well as economic losses. Such attitudes of earth pushed the frontiers to develop innovative monitoring strategies for the earth system. To make that real, although, will require coherent and real-time data by observing the earth behavior contiguously. Here sensors are very powerful device which used for real time monitoring. For removing such type occurrences we choose the sensor network and GSM. The sensor is a major device in electronics for measuring physical data from the environment. In the direction of the landslide prediction, sensor can play a great role, where sensor connected with wireless protocol can make it very useful for remote areas landslide mapping, detection, analysis and prediction etc. A wireless sensor network consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, including temperature, sound, pressure, etc. is found be worthwhile.

The wireless LANs have been deployed at many places, small or big, houses or commercial complexes mainly because of their ease of installation and use. The IEEE 802.11-based WLAN presents new challenges for network and information security administrators. Whereas the security requirements of wired Ethernet deployments are relatively simple, security of a WLAN is somewhat complex. 802.11-based WLANs broadcast radio-frequency data for the client stations to receive. Hence, there are complex security issues that involve augmenting the 802.11 standard. This work critically reviews main security flaws of Wired Equivalent Privacy and suggests a new approach of automatic key management and refresh of WEP key so that attacker could not get sufficient time to guess the key.

Here, in this study, a simple designs of rectangular Micro strip patch antenna is proposed that is investigating for enhancing the impedance bandwidth for wideband applications, especially for Mobile Services (1.885-2.025 GHz) and WLAN (2.40-2.48 GHz). On the conducting patch T shaped slot has been cut. The % impedance bandwidth (VSWR ≤ 2) at -10 dB return loss for band 1 comes out to be about 19.5%, ranging from 2.194 GHz to 2.667 GHz and 6.7 % ranging from 3.493GHz to 3.773 GHz for band 2

Diabetic Retinopathy is most normal retinal maladies. Diabetic Retinopathy (DR) is a dynamic retinal malady and ought to be distinguished as right on time as could be allowed. To help the ophthalmologists in mass screening of diabetes licenses, the keen identification and determination of Diabetic Retinopathy (DR) is intense to spare the patient's vision and. We display another shrewd framework for identification and arrangement of various DR sores i.e. smaller scale aneurysms (MAs), Haemorrhage (H), Hard Exudates (HE), and Cotton Wool Spots (CWS) in this paper. We proposed another brilliant framework in which every conceivable sore present in a fundus picture prosecuting Gabor channel bank by division. Every sore followed by components sets and distinctive properties for the order of injuries. With the assistance of disparate execution parameter and the outcomes, the evaluation of proposed framework are performed utilizing retinal picture data bases demonstrating the acknowledgment of proposed framework.
