Today, we witness the emergence of smart environments, where devices are able to connect independently without human- intervention. Mobile ad hoc networks are an example of smart environments that are widely deployed in public spaces. They offer great services and features compared with wired systems. However, these networks are more sensitive to malicious attacks because of the lack of infrastructure and the self-organizing nature of devices. Thus, communication between nodes is much more exposed to various security risks, than other networks. In this paper, we will present a synthetic study on security concept for MANETs, and then we will introduce a contribution based on evaluating link quality, using ETX metric, to enhance network availability.
