Mobile ad-hoc networks (MANETs) are susceptible to attacks by malicious nodes that could easily bring down the whole network. Therefore, it is important to have a reliable mechanism for detecting and isolating malicious nodes before they can do any harm to the network. One of the possible mechanisms is by using trust-based routing protocols. One of the main requirements of such protocols is to have a cost-effective trust determination algorithm. This paper presents the performance analysis of a recently developed trust determination algorithm, namely, the neighbor-weight trust determination (NWTD) algorithm. The performance of the algorithm is evaluated through simulation using the MANET simulator (MANSim). The simulation results demonstrated the reliability and effectiveness of the algorithm in identifying and isolating any maliciously behaving node(s) in a timely manner.

The nature of crime has dramatically changed after the revolution of the new digital era. It is no longer based on violence but on the criminal computer abilities and technical expertise. This paper presents a comprehensive comparison between the Jordanian digital law 2015 and the Omani information technology digital crime law 2010. The results of this study indicate that the Jordanian Digital law requires some enhancements in order to cope with the trends of the ever-changing nature of the digital crimes.
