As the rate of sexual crimes soars, new law mandates the sex offenders to wear an electronic anklet identifying their location. Here a middleware is needed to monitor and manage wide area of a number of entities. The existing middleware is somewhat inefficient in covering such vast area of specific application. This paper proposes a context-awareness middleware structure which monitors the distance...
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...
In order to reliably support various services using multi-agent system, the faults in the system need to be tolerated. While various schemes have been proposed for fault tolerant MAS, the replication approach provides the basis of short recovery latency, less intrusive with respect to the execution time, and high scalability. In this paper we propose a new replication scheme making a decision on either...
The usage of sensor network is rapidly growing, and monitoring mobile object is one of important applications of sensor network. A sensor node in the network has limited energy, and thus one key issue here is energy efficiency to prolong the network lifetime. In this paper we propose a new scheme minimizing the energy consumed for handling the path loss problem occurring between the tracking sensor...
