Wireless Sensor Network (WSN) is an essential part and key enabler of the Internet of Things (IoT), where hundreds or thousands of little smart perception or ascendency lymph glands are interconnected to transmit detection/monitoring entropy or ascendance statements. In order to implement detection/monitoring or controller servicings 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 conformity. Therefore, IPv6 Over WSN is getting more and more enquiry and exploitation (R&D) aid from both industriousness and academia.
