Denial of Service (DoS) attack is one of the major problem in today's Internet. It constitutes the hardest security problems nowadays. Particularly Distributed Denial of Service (DDoS) attack have severe impact. The main aim of a DoS is the disruption of services by attempting to control access to a system or service instead of overthrowing the service itself. Disruption-Tolerant Networks (DTNs...

A Mobile Ad hoc Network (MANET) is a collection of wireless computers (nodes) communicating over multihop paths, without infrastructures such as base stations and access points. Nodes must cooperate to provide necessary network functionalities. The Dynamic Source Routing (DSR) protocol is a principal routing protocol in MANET, where security can be compromised by a “Black Hole” attack. In this ...

Renewed interest in the effects of narcissism in the media has generated a closer examination of the phenomenon. This coupled with an increase in academic misbehavior among both high school and university students has provided an opportunity to scrutinize the effects of narcissism on attitudes toward academic dishonesty. The authors investigated this relationship and the presence of intervening...

Characteristic for ad-hoc wireless sensor networks is the lack of a centralized control. Instead each node serves as a routing device, which is able to forward packets to its neighbors1 and receive packets from them. Node movement is allowed, but rare for sensor nodes. Each node is able to be switched on and off at any time depending on its power saving configuration. Such networks are extremel...

This study aimed to examine the similarities and differences between teachers’ and students’ causal explanations of classroom misbehavior. In-depth semi-structured interviews were conducted with twelve teachers and eighteen Grade 7-9 students. The qualitative data were analyzed, in which the attributed causes of classroom misbehavior were categorized into student, family, school and peer factor...

Word of mouth (WOM) and observational learning (OL), as two types of social interaction, have been generally studied by researchers. And they have significant impacts on consumers’ purchase decision. However, few researches pay attention to their influences on online misbehavior. In this paper, we respectively examined the effect of these variables on consumers’ misbehavior. Moreover, Machiavel...

The purpose of the present research was to investigate the relationships between justice perceptions, employee's misbehavior and cynicism to organization because very few studies have looked at the role of justice and cynicism in the prediction of employee's misbehavior in public organizations. According to the purpose of study, the present research is developmental research. Also according to ...

Due to the dynamism of topology, sharing of bandwidth and constraint of resources in wireless nodes, the provision of quality of service (QoS) for routing in mobile ad hoc networks (MANETs) presents a great challenge. Security is another crucial aspect of providing QoS since the existence of malicious nodes present all kinds of threats to MANETs. Although a number of mechanisms have been propos...

Wireless Body Area Network (WBAN) is a promising technology that having significant number of applications in healthcare. Despite several benefits, WBAN susceptible to security attacks, particularly related the node misbehavior attacks such as sinkhole, wormhole, blackhole, and grayhole attacks. In this research work, performance AODV protocol against wormhole sinkhole has been analyzed. This c...
