Lagos: Context management system for a sensor-robot network

摘要

The purpose of this paper is to develop a new context management system software that creates applications easily in a sensor-robot network. Following four functions are required to realize a context management system. (1) search contexts. (2) update the current context. (3) fuse two contexts. (4) reject fusion requests. To solve these problems, this paper proposes LaCoS(Layer of Context Sharing). LaCoS uses Selection and Insertion function, respectively, to solve (1) and (2). LaCoS defines new function “FUSE” to solve (3) and “REJECT FUSION” to solve (4). We implemented LaCoS and conducted experiments to confirm that LaCoS successfully equips four functions.
