Security is a critical problem when implementing Mobile Ad Hoc Networks (MANETs) and is widely acknowledged. This paper describes the effects of selfish nodes in MANETs. An Ad Hoc Network is a collection of wireless mobile hosts forming a temporary network without the aid of any centralized administration or standard support services. One of the different kinds of misbehavior is node selfishnes...

The harmful attack against Wireless Sensor Networks (WSN) is Node Replication attack, where one or more node(s) illegitimately claims an identity, are also called clone attack due to identity theft. The Node replication attack can be exceedingly injurious to many important functions of the sensor network such as routing, resource allocation, misbehavior detection, This study proposes a method R...

In late-age silicon, soft errors become an issue even for low-margin products. Since classical hardening techniques are associated with costs which may not be acceptable for such ICs, selective hardening which targets only a subset of all possible soft errors has been suggested. We propose a soft error selection method based on severity of an error’s impact on system behavior. Some soft errors ...

One approach to detecting insider misbehavior is to monitor system call activity and watch for danger signs or unusual behavior. We describe an experimental system designed to test this approach. We tested the system’s ability to detect common insider misbehavior by examining file system and process-related system calls. Our results show that this approach can detect many such activities. *
