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.
