Service-Controlled Networking: Dynamic In-Network Data Fusion for Heterogeneous Sensor Networks

Recent advances of Wireless Sensor Networks technologies has witnessed the dynamic changes of our daily life. With the sensors deployed everywhere, people may benefit from various services (weather service, traffic information, environment sensing, etc.) based on these sensor networks. However, how to collect/manage/process those various sensor dates from heterogeneous sensor networks still remain challenges. In this paper, we introduce our recent research effort and elaborate how we try to overcome these challenges with a large scale test bed environment. We first propose a novel concept named service-controlled networking (SCN), a network middleware which is capable to dynamically process data fusion at In-Network level. We then verify the usefulness by extensive experiment evaluation. Last, we discuss the future direction of SCN.
