Wireless Sensor Network (WSN) is an essential part and key enabler of the Internet of Things (IoT), where hundreds or thousands of little smart detection or ascendency leaf nodes are interconnected to transmit perception/monitoring data or command statements. In order to implement detection/monitoring or ascendance religious services at a large scale with seamless connection to the Internet, IPv6 would be the best solution due to its many advantages including its highly scalable address scheme, stronger security department, and full Internet deference. Therefore, IPv6 Over WSN is getting more and more inquiry and growing (R&D) care from both manufacture and academia.
