A mobile ad hoc network (MANET) is a collection of wireless mobile nodes forming a temporary network without any established infrastructure. MANETs are generally more vulnerable to security threats than fixed wired network due to its inherent characteristics such as absence of infrastructure, dynamically changing topologies. The selection of IDS operating node is one of critical issues because of energy limited feature of a MANET. In this paper, we propose a cost-effective IDS operating node selection scheme by solving cost minimization problem in a MANET. The results illustrate that our proposed algorithm can reduce the total cost while maintaining appropriate security level in a MANET. [ABSTRACT FROM AUTHOR]

Ontology merging and alignment is one of the effective methods for ontology sharing and reuse on the Semantic Web. A number of ontology merging and alignment tools have been developed, many of those tools depend mainly on concept (dis)similarity measure derived from linguistic cues. We present in this paper a linguistic information based approach to ontology merging and alignment. Our approach is based on two observations: majority of concept names used in ontology are composed of multiple-word combinations, and ontologies designed independently are, in most cases, organized in very different hierarchical structure even though they describe overlapping domains. These observations led us to a merging and alignment algorithm that utilizes both the local and global meaning of a concept. We devised our proposed algorithm in MoA, an OWL DL ontology merging and alignment tool. We tested MoA on 3 ontology pairs, and human experts followed 93% of the MoA's suggestions.
