| Outline of Final Research Achievements |
IoT devices have private addresses, and they are deployed behind firewall and NAT. In many reasons, they cannot use the existing network in the deployment sites, but they use specially deployed bandwidth limited cheap LTE for IoT communications. In such a case, WebSocket (originally developed for browser-to-cloud communications) can be used for IoT transports, however it contains priority-control problem and keep-alive connection problem. So, we cannot simple use WebSocket for IoT. This research have solved these issues. We have developed priority-control algorithm and connection-management algorithm to make WebSocket useful in IoT communications.
