Sinkholes represent the main hazards in karst areas, and are related to presence of natural and anthropogenic cavities. In order to mitigate the risk related to sinkholes, identification of likely premonitory signs preceding the catastrophic phase of collapse may be extremely important. Remote sensing and surface monitoring can be used at this aim: multi-pass spaceborne Differential Synthetic A...

Wireless sensor networks (WSNs) have gained huge popularity in various new fields. The direct use of each of these sensors individually is to detect its surrounding conditions such as temperature, pressure, sound, motion etc. whereas a collection of such nodes finds application in various large scale management systems such as healthcare, disaster and traffic management programs. In most of the...

Recent advances in wireless networks have prompted much research attention in the area of wireless sensor network (WSN). Sensor network consists of hundreds to thousands of low power multifunctioning sensor nodes operating in hostile environment with limited computational and sensing capabilities. These sensor devices are susceptible to various attacks such as selective forwarding or sinkhole a...

Sensor networks are playing an important role in many applications. These networks mainly used as monitoring tool are deployed in harsh and unsupervised environment. Hence securing these nodes and the data which is being transmitted becomes a basic requirement. To adapt security to the network, the study uses cluster-based arrangement of nodes. The encryption key is generated based on location,...

Wireless sensor network is an area where there has been alot of significant developments. These sensors are hugely utilized in many applications like military applications, home automation, and environment surveillance. An application where confidential data is being transmitted requires to be protected from different types of attacks. Though the nodes are authenticated, they are liable to get ...

-Sensor networks consist of large number of nodes with limited energy, computation and transmission power. Each node in the network helps every other node by forwarding their packets to reach the destination .Since these nodes operate in a physically insecure environment; they are vulnerable to different types of attacks such as sinkhole and wormhole. These attacks can inject malicious packets ...

In this paper, we introduce TinyTermite. TinyTermite is a novel AI routing algorithm that is reliable and secure against selective forwarding and replay attacks. TinyTermite is fully implemented on TinyOS based Intel Mote 2 platform and the experiments were done to compare its performance with that of the traditional Termite algorithm. Our results show that the TinyTermite reduces the energy co...

On the basis of qualitative osteological characters, six anuran taxa are present in the late Pliocene Inglis 1A Local Fauna, an apparent natural trap in karst Eocene limestone. They are Scaphiopus holbrookii, Gastrophryne carolinensis, Hyla cinerea, Rana catesbeiana, Rana capito, and Bufo defensor n. sp. (that appears to be related to Bufo terrestris). The predominance of adults in the size cla...

Sensors are tiny devices utilized as an essential component in many applications. These nodes are easing human effort by accomplishing task without any human intervention in areas including disaster relief, harsh environments. These devices are liable to get compromised as these nodes are unattended after deployment. Hence encryption keys are to be used to provide reliability to the data being ...
