Implementasi Teknologi Mobile Agent pada Layanan Printer Berbasis Lokasi

Abstract

Most devices in ubiquitous network environment have limited memory and processing power, thus they can’t provide all services even when in suitable locations. Mobile agent technology could be implemented to improve resource efficiency. The goal of this research is to implement mobile agent technology for location-based printer service. In this research a scenario-based UML design analysis method will be used. To develop the system with mobile agent technology, a state-of-theart agent platform – JADE is used. The system consists of four parts: (1) mobile agent server, (2) location-based service server, (3) printer service, (4) client. Mobile agent is successfully implemented for location-based services. There are several advantages of mobile agent for location-based services: (1) can be used as alternative solution to distribute services in ubiquitous computing environment, (2) service management is easier and cheaper because no additional infrastructure needed when new service added, (3) easy to maintain because system consists of an agent that easy to debug and agent component easy to replace without affecting other component in the system, (4) system model is highly scalable. However, there are also disadvantages of mobile agent for location based services: (1) specifically in this case, the network infrastructure needs the addition of two computer equipment that will act as mobile agent server and location-based service server, (2) mobile agent security is still an open research. Our future researches are to include more service available, improve client graphical user interface, considering geographical proximity between service requester and provider, add compatibility with more operating system, improve jobs distribution algorithm and add domain name system entity
