An Adaptive Approach to Detect Malicious Node in MANET.

Abstract

Mobile Ad hoc NETworks (MANET) are the wireless networks of mobile computing devices without any support of a fixed infrastructure. Securing such networks is non-trivial. Most security schemes suggested for MANETs tend to build upon some fundamental assumptions regarding the trustworthiness of the participating nodes and the underlying networking systems without presenting any definite scheme for trust establishment. For defining trustworthiness of the nodes different trust parameters are used by different authors in the literature. In order to calculate more accurate trust value with low overhead we analyze these different parameters in groups. Furthermore we also assign some weights to these parameters. As a output of this work we will be able to give a group of parameters to detect malicious node in the network.
