Performance evaluation of secure AODV with trust management under an energy aware perspective

Abstract

Ad-hoc networks allow nodes communication without an infrastructure, so they can be used in many environments. This lack of infrastructure introduces many security threats to the nodes in the network. Communication between nodes must be reliable, and protocols for MANETs need to make it possible. Due to the wireless channel and to the possible malicious behavior of nodes, it is necessary to introduce security mechanisms to avoid possible attacks in the network. The introduction of a trust management system on a well-known protocol such as SAODV protocol can protect against more attacks from malicious nodes, making wireless communication reliable and more secure. In this contribution Black hole and gray hole attacks will be detected, so communication will not be disrupted. Moreover, in order to understand as the energy consumption due to additional introduced security mechanisms, an energetic analysis is also performed on SAODV with and without trust management.
