Today, multi-agent technologies are widely used for realizing prevalent ubiquitous computing applications, in which service discovery is a critical task for finding a particular service instance. While JADE is a popular system for multi-agent applications, its directory facilitator (DF) used for service discovery employs a sequential search approach, which shows degraded performance when the number...
Multi-agent system in the ubiquitous computing environment can provide customized services to the users by effectively utilizing the distributed resources. The existing dynamic load balancing approach invokes the migration of agents even for temporal imbalance of the loads. In this paper we propose a prediction-based dynamic load balancing scheme which can effectively avoid unnecessary agent migration...
In ubiquitous environment intelligent and transparent services are provided to the users anytime and anywhere. Ubiquitous systems can be effectively implemented using the agent technology, while the agent platform supports efficient and stable interaction among the agents. In this paper we propose a load-balancing scheme which considers agent state for fair and efficient resource allocation to the...
Context-awareness is one of the key features of ubiquitous paradigm. To intelligently and sensitively deal with dynamic environment, a methodology specifying the relationships between the contexts and services needs to be developed. It is difficult to verify the correctness of the existing models on context with respect to timeliness. In this paper we propose an approach which includes timing constraint...
