A mobile ad hoc network (MANET) is a collection of autonomous nodes that communicate with each other by forming a multi-hop radio network and maintaining connections in a decentralized manner. Security remains a major challenge for these networks due to their features of open medium, dynamically changing topologies, reliance on cooperative algorithms, absence of centralized monitoring points, a...

Self organization characteristics of Mobile ad hoc networks (Manet) make traditional security solutions inapplicable. In Manet, any node can be router, and can perturb the routing operation by broadcasting incorrect topological information, making the construction of routing table, which is the primary goal of routing protocols, the more vunerable operation. Thus, in such environments, there is...

The Pastry [2] Distributed Hastable (DHT) provides decentralized peer-to-peer services in a scalable and efficient manor. Peers do not have to provide links to each node in the network, but only to a small subset of nodes. Due to this, lookup requests for services offered in the peer-to-peer system mostly can not be sent to the destination directly, but have to be forwarded to a node that is lo...

Vehicular Ad-hoc Networks (VANETs) are highly dynamic network and prone to many kinds of attacks. One class of attacks known as routing misbehavior targets the routing process of the networks. Grayhole attack is a malicious change in the routing process of effected nodes. Such node takes part in routing process but drops the packet when it is required to forward the packet to other nodes. This ...

There has been little empirical research into misconduct and misbehavior among community research workers who recruit and collect data in vulnerable and marginalized health populations and are also members of those same communities. We conducted qualitative interviews with community research workers and traditional research assistants to understand the context and consequences of misbehaviors t...

Currently, the majority of American Indian families live in urban areas. A number of statistics demonstrate that urban American Indian families deal with a variety of stressors such as poverty and isolation. However, very little is known about how these families perceive their lives. This report provides an exploratory study examining the status of 20 urban American Indian mother/child dyads. M...

Tliis study examined the influence of teaching assistant attire in the university classroom. Significant relationships were found between instructor attire and student cognitive learning, affective leaming, and ratings of instruction. Analysis of variance indicated significant differences in these variables by levels of teaching assistant dress. Significant negative relationship was found betwe...

Reputation systems in mobile ad-hoc networks can be tricked by the spreading of false reputation ratings, be it false accusations or false praise. Simple solutions such as exclusively relying on one’s own direct observations have drawbacks, as they do not make use of all the information available. We propose a fully distributed reputation system that can cope with false disseminated information...

a r t i c l e i n f o The activities of misbehaving customers represent a significant problem for organizations across diverse sectors and industries. Customer misbehavior signifies behavior within the exchange setting that deliberately violates the generally accepted norms of conduct in such situations. The core aim of this study is to advance understanding of the antecedents to past customer ...
