Recently, smart spaces are being created using RFID or USN technologies in ubiquitous computing environments, and the number of researches and applications related with context-aware systems, which process sensed data collected from numerous sensors and provide automated services properly according to situations, are ever increasing. There are also sharp increase in demands and needs for location-based...
Program codes running on the sensor nodes need to be updated from time to time to fix bugs, tune the parameters, insert new functions, or delete useless codes. In this paper, we propose a policy-based reprogramming framework that can optimize the reprogramming process based on the execution characteristics of modules that constitute the WSN applications. To accomplish this we model the characteristics...
