The domain of Wireless Sensor Networks (WSNs) applications is increasing widely over the last few years. As this new type of networking is characterized by severely constrained node resources, limited network resources and the requirement to operate in an ad hoc manner, implementing security functionality to protect against adversary nodes becomes a(More)
Wireless sensor networks (WSNs) are quickly gaining popularity due to the fact that they are potentially low-cost solutions that can be used in a variety of application areas. However, they are highly susceptible to attacks and it is very probable that an intruder catches already existing security measures out. AWISSENET (Ad-hoc personal area network &(More)
The context of our work is an image database engineering research project (called IkoSem) which aims to provide modelers with a framework (and a corresponding methodology) for prototyping a database from a collection of images and specifications of users’ requirements. Early in our project, we identified a major need, namely that of a generic model coupled(More)
Wireless Sensor Networks (WSN) are quickly gaining popularity due to the fact that they are potentially low-cost solutions, which can be used in a variety of application areas. However, they are also highly susceptible to attacks, due to both the open and distributed nature of the network and the limited resources of the nodes. In this paper, we propose a(More)
