Title: Hiroshi Dempo: Innovator in Sensor Network Systems
Introduction
Hiroshi Dempo is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of sensor network systems, holding a total of 11 patents. His innovative work focuses on enhancing the efficiency and reliability of network systems through advanced load distribution methods.
Latest Patents
Dempo's latest patents include a network system designed to optimize the performance of sensor nodes. This system allows for the distribution of load from high-load edge nodes to low-load edge nodes that receive the same semantic information. The sensor network comprises a sensor node that generates semantic information, a broker node that transfers this information, and a server node that registers filter conditions for the information to be acquired. When a broker node enters a high-load state, the system searches for a low-load broker node to switch the accommodating relationship of the sensor node, ensuring continuous operation.
Another notable patent is an event delivery system that reduces bottlenecks by alleviating load on a rendezvous node. This system includes publisher nodes, subscriber nodes, a rendezvous node, and broker nodes. The rendezvous node monitors traffic volume and determines specific event information for load distribution when traffic exceeds a predetermined value. Each broker node detects its role in the delivery route and constructs new routes to bypass the rendezvous node, enhancing overall system efficiency.
