Implementation Methodology of Geographical Overlay Network Suitable for Ubiquitous Sensing Environment

Abstract

To handle ubiquitous sensor data, we have been developing a geographical-location-based P2P network called “Mill”. In a ubiquitous sensing environment, data manipulation by users and sensing devices may have some characteristics. For example, sensor data are constantly generated and users keep getting these data in a particular region. When handling such an operation on existing overlay networks, relaying nodes have to process many queries issued by users. In this paper, we discuss an implementation methodology of “Mill” considering the characteristics of data manipulation. And we can also support event driven behaviors and consider the feasibility of the deployment through the implementation based on HTTP. The performance of the implementation shows that one Mill node can handle ten thousands users and sensing devices.
