A method of task assignment in a distributed processing system including a plurality of processors is proposed. The method of task assignment includes calculating utilities of tasks to be processed in execution units included in each processor and arranging the calculated results in descending order; calculating utility difference values between the execution units included in each processor and outputting a highest difference value; comparing a utility of the task with the output highest difference value; designating the task to be assigned to the execution unit having the lowest utility in a processor in which the highest difference value is generated when the utility of the task is less than or equal to the output highest difference value; repeating the calculating, comparing, and designating in the order of the arranged tasks; and assigning the tasks to the designated targets.

Provided are a system and method for determining whether to provide service and a content of the service based on ubiquitous-based context information. The method includes the steps of registering at least one context-aware service (CAS); determining whether sensors associated with the CAS are registered; when all the sensors are registered, checking all contexts associated with the CAS; upon receipt of a CAS request, receiving context information from the sensors and determining whether the context information satisfies the contexts; and providing the CAS if the context information satisfies at least one of the contexts. With the flexible engine determining whether to provide service corresponding to a current context even though all context information constituting the CAS is not collected, information is quickly provided upon receipt of a service request from a user.

A host system having a device driver development tool and a target system having a device driver agent, the tool and the target system separated from each other and interconnected with a communication network. The driver agent device communicates with the target system, receiving and processing various service requests from the device driver development tool, and transmits the processed services to the host system through the communication network. Thr driver agent determines types of the services requested from the device driver development tool and performs services based on the types of the services determined. Accordingly, the device driver can be adapted to the target system and tested without complex procedures to effectively reduce time and manpower needed for the device driver development.

Provided are a system and method for position awareness that can be used indoors in a large-scale environment and can minimize generation of radio frequency (RF) and ultrasonic waves in a wireless sensor network including low-priced sensor nodes capable of precise position measurement, thus improving energy efficiency by reducing unnecessary power consumption. The method includes the steps of: (a) calculating initial position coordinates using beacon information received from adjacent beacons through a broadcast beacon solicitation signal, sending a synchronization signal to the beacons, and synchronizing the beacons; (b) receiving ultrasonic waves generated from the adjacent beacons activated by a broadcast start message, and calculating position coordinates; and (c) when the calculated position coordinates correspond to a predetermined hand-off threshold position, transmitting a hand-off process message to a newly activated beacon, and executing a hand-off process routine.
