Multi-channel Buffer Enabled Technique for Video Streaming in IEEE 802.15.4

Increase in the use of wireless technologies has opened doors for development of various wireless applications to provide solutions to different problems in domains like, security and surveillance, entertainment, transportation, communication and education. To reduce the overall cost and power consumption of the systems to be deployed in developing countries, short range wireless technologies like ZigBee (IEEE 802.15.4) are gaining popularity. However, due to limitation of data rate, some applications that involve transmission of heavy data are still considered far-fetched. This paper presents a technique that enables ZigBee to be utilized for heavy data transmission such as video streaming. For this purpose, a technique based on the concept of multi-channel and buffer is introduced in this article. In order to illustrate the efficiency and reliability of the proposed technique, it is compared with currently available video streaming techniques like, single channel buffer less, single channel buffered and multi-channel buffer less. Several simulations are performed on these available techniques to gauge the efficiency of these techniques at low data rate of around 250 kbps. The results of the simulations are then compared with the simulation results of the proposed technique to ensure its efficacy.
