Abstract: Accessing end devices (nodes) in the Internet of things (IoT) with a unique IP address is possible with the evolution IPv6 and 6LoWPAN. which is an open stack developed by IETF to provides communication between LoWPAN devices and the internet. 6LoWPAN Border Router is the gateway between nodes and internet which connects 6LoWPAN devices to the Internet and also responsible for controlling traffic between IPv6 and IEEE 802.15.4 interfaces. 6LoWPAN Networks are implemented by several ways, but some are open standards which can be executed on development boards like Raspberry Pi, Beagle bones etc. The design and implementation of 6LoWPAN border router with an embedded Web server and implement the bridge between 6LoWPAN devices to the internet (IPv4 as well as IPv6). The border router is built around a 32-bit ARM Cortex M3 microcontroller and runs the network-enabled operating system Contiki in version 2.7.The network layer uses IPv6 and Layer-3 forwarding between these different link-layer technologies.

Keywords: Internet of Things, 6LoWPAN Border Router, IPv6, IEEE 802.15.4, Contiki-OS.
