A Comparative Evaluation of Mining Techniques to Detect Malicious Node in Wireless Sensor Networks

Wireless sensor networks have gained attention over the last few years and have significant applications for example remote supervising and target watching. They can communicate with each other though wireless interface and configure a network. Wireless sensor networks are often deployed in an unfriendly location and most of time it works without human management; individual node may possibly be compromised by the adversary due to some constraints. In this manner, the security of a wireless sensor network is critical. This work will focus on evaluation of mining techniques that can be used to find malicious nodes. The detection mechanisms provide the accuracy of the classification using different algorithm to detect the malicious node. Pragmatically the detection accuracy of J48 is 99.17%, Random Forest is 80.83%, NF Tree is 81.67% and BF Tree is 72.33%. J48 have very high detection accuracy as compared with BF Tree, NF Tree Random Forest.

A New Survey of Grime's Graves—First Report

SummaryNo accurate survey of a flint mine exists. It is planned to carry out such a survey at Grime's Graves over a period of several years. Its purpose is to study the growth of the flint-mine complex, the evaluation of mining techniques and ancillary industries, and trade relations; and to discover settlement sites related to the industrial complex. Preliminary field work was carried out in the summer of 1972. This included geophysical and chemical surveys, ground surveys, and aerial photography. Excavations were undertaken to test the results of the scientific surveys. A detailed contour map of the site was prepared by photogrammetry.
