Remote triggered black hole filtering describes a method of mitigating the effects of denial-of-service attacks by selectively discarding traffic based on source or destination address. Remote triggered black hole routing describes a method of selectively rerouting traffic into a sinkhole router (for further analysis) based on destination address. This document updates the "IPv6 Special Purpose...

O ver the last 25 years, a series of studies has investigated the diurnal formation and destruction cycle of temperature inversions in valleys and basins (for a review see, e.g., Whiteman 1990). In most of the valleys and basins that have been studied to date, advective influences produced by the well-known, diurnally reversing upand down-valley wind systems have greatly complicated the analyse...

wireless sensors having limited capabilities, because of these factors sensors possess huge attacks like sinkhole, worm hole, Sybil, flooding, etc. a lot of research work already done, but no one implemented secure routing protocol to mitigate all these attacks. Some proposals came on security of wireless sensor network which controlled only one or two attacks. We proposed Secure Routing in Clu...

Security is very critical parameter in sensor networks. Securing the WSN needs to make the network support every security property. Security attack is a concern for wireless sensor networks because of usage of very low capacity devices in the systems and physical accessibility to sensor nodes. Therefore to prevent confidential information from being stolen, it is important to provide secure com...

Suitable route determination for linear engineering structures is a fundamental problem in geology. Rapid evaluation of alternative routes essential, and novel approaches are indispensable. This study aims to integrate various InSAR (Interferometric Synthetic Aperture Radar) techniques sinkhole susceptibility mapping the Kirikkale-Delice Region Turkey, which formations have been observed evapor...
