IOT stands from Internet of things and it is most popular from recent years. This is embedded with software and connected to various devices. This is used to monitor the various devices by using Internet and it controls the devices. This paper integrates the low power devices into the Internet that connects between the 6LoWPAN and sensor notes through gateway. The 6LoWPAN is a low-power wireless mesh network, where everything has its own unique IPv6 address that allows the connectivity directly to the Internet using open standards. Interfacing between CoaP and UDP presents interfacing between the CoAP and UDP Protocol in which CoAP is the application protocol and UDP is the transport protocol. We interface 6LoWPAN and I.E.E.E. 802.15.4 by three mechanism-first, header compression, we compress IPv6 header for optimize use of common field values. Some of the fields of Header are omitted from a packet as the adaptation layer can generate them from information obtained from link-level carried in the 802.15.4 frame. Moreover, to perform the routing in 6LoWPAN network, RPL is used, which is a destination-oriented DAG (DODAG) between the different IPv6 nodes. We also interfaced the 6LoWPAN and CoAP through RPL using UDP Protocol for various constrained nodes in Contiki Operating system using Cooja Simulator in order to examine the performance of 6LoWPAN network.
