In this paper the design of a dynamic Routing system, called Hierarchical routing system, has been developed. It splits traffic networks into several smaller and less complex networks by introducing a hierarchy. The Hierarchical routing system therefore consists of several distributed Routing systems where each of it is responsible for one network of the hierarchical network. The route optimiza...

Recognizing and distinguishing antonyms from other types of semantic relations is an essential part of language understanding systems. In this paper, we present a novel method for deriving antonym pairs using paraphrase pairs containing negation markers. We further propose a neural network model, AntNET, that integrates morphological features indicative of antonymy into a path-based relation de...

Stigmergic systems solve global problems by using indirect communication mediated by an environment. Because they are localized and dynamic, stigmergic systems are self-organizing, robust and adaptive. These properties are useful for creating survivable systems, but stigmergic systems also raise new security concerns. Indirect communication makes systems more vulnerable in an open and hostile e...

As a result of the rapid growth of computational needs, grid computing is gaining more and more attention. It becomes a viable high-performance alternative to the traditional supercomputing environments. However, grid performance can still be improved by effectively and efficiently utilizing the available grid resources using a good load balancing algorithm. Ant colony optimization is one of th...

To tackle problems emerging with rapid growth of information networks in scale and complexity, bio-inspired selforganisation is a promising design principle for future networks. However, self-organising systems fall into local optima or converge slowly under some environmental conditions. This can make self-organising systems slow to adapt to environmental change, despite robustness against env...
