Abstract

Consider the problem of detecting whether a compromised router is maliciously manipulating its stream of packets. The concerned with a simple yet effective attack in which a router selectively drops packets destined for some victim. Modern networks routinely drop packets when the load temporarily exceeds their buffering capacities. Previous detection protocols have tried to address this problem with a user-defined threshold: too many dropped packets imply malicious intent. This heuristic is fundamentally unsound; setting this threshold is, at best, an art and will certainly create unnecessary false positives or mask highly focused attacks. They have designed, developed, and implemented a compromised router detection protocol that dynamically infers, based on measured traffic rates and buffer sizes, the number of congestive packet losses that will occur. Once the ambiguity from congestion is removed, subsequent packet losses can be attributed to malicious actions

Abstract

In view of constantly rising power tariff and penalties imposed by the State Electricity Boards/Utility companies, it is imperative for any HT & LT Industry/Consumer to install an automatic power factor controller system for curtailment of power factor penalty and also to save energy by consistently maintaining higher power factor. An intelligent automatic power factor controller unit is used to improve the power factor, it usually consists of a number of capacitors are controlled by a regulator that measures power factor in an electrical network. Depending on the load and power factor of the network, it will switch the necessary blocks of capacitors in steps to make sure the power factor stays above a selected value (usually demanded by the energy supplier). It has been implemented and tested using intelligent automatic power factor controller in STAS Spinning Mill P Ltd, Madurai, Tamil Nadu.
