WSN-based Energy-Efficient Data Communication Protocol for Smart Green Building

One of the important design issues of smart green buildings is to make use of energy, water and other resources efficiently. Improving the energy efficiency of buildings is an important step towards a more sustainable lifestyle, leading to significant cost savings for the residents. Wireless sensor network will be responsible for the majority of the growth in smart green building systems over the next decade since it provides the necessary information to the smart green building system, allowing it to monitor and control the physical environment of the building. Since the energy saving plays the main challenge in the design and implementation of wireless sensor networks, we proposed an energy efficient data communication protocol for smart green building environment which is an integration of clustering and routing in sensor network. In our approach, we also performed network coding during the data routing in order to achieve the additional power saving in the cluster head nodes. Simulation results are provided to show the efficacy of the proposed method in terms of the throughput and end-to-end delay. In addition, the results show significant improvement of proposed method in the network lifetime over other technique.
