6LoWPAN based smart home architecture for the smart future

Abstract

6LoWPAN is an emerging area of research. It helps to extend network architecture for WSN which allows end-to-end connectivity between a 6LoWPAN node and any IP devices of the network. To make a low power consumption mesh network, 6LoWPAN is a promising solution on a simple embedded system. Target is to carry IPv6 packets efficiently within a small link layer frame IEEE 802.15.4. Currently the absence of IP address hinders the process of accessing sensors directly. In remedy, IP supporting devices are necessary. Here according to 6LoWPAN technology each sensor will have a unique IPv6 address that will be auto-con gured. So, the user can easily access the sensors data directly from the Internet without any supporting device. In our home automation, we have implemented our proposal through simulator COOJA which is basically a simulator designed for wireless sensor network. It is a part of exceptionally versatile in performing various tasks and it works in framework Contiki. It has unlocked source where an integrated Internet Protocol Suite based on TCP/IP stack and multitasking takes only a few Kilobytes of RAM and ROM. A Contiki-based 6LoWPAN gateway is designed to interconnect 6LoWPAN nodes with the Internet IPv6. We have implemented our 6LoWPAN based network simulation in COOJA.We have found a better End to End communication, mobility, scalability and lower overhead which makes the system more convenient compare to other technology based home automation.
