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 control condition knobs are interconnected to transmit detection/monitoring info or ascendance statements. In order to implement perception/monitoring or controller divine 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 system, and full Internet abidance. Therefore, IPv6 Over WSN is getting more and more enquiry and growth (R&D) care from both industriousness and academia.
