Implementation of smart elevator system based on wireless multi-hop AdHoc sensor networks

In modern day world, time has become a precious resource. Therefore, different strategies and techniques are constantly being employed in all fields of life to save every bit of time. Increasingly many of such applications involve wireless sensor networks. A highly potential system that can be made significantly more efficient using WSNs is an elevator system. There have been numerous attempts to improve the serving efficiency of the elevator system over the course of time. This paper proposes to utilize the elevator system in a more productive manner so that more number of people can be served in a lesser time. Hence, people will be able to spend this valuable time on other important and crucial matters rather than waiting for the elevator and wasting their time in vain. To achieve this goal, we implement the elevator system based on a wireless adhoc network of intelligent floors (equipped with sensors) which can communicate with each other in a multi-hop fashion. In this way, every floor is aware of the traffic conditions, i.e., the number of upward/downward requesting-passengers, waiting at every other floor and the elevator positions in real-time and hence can make efficient decisions of where to direct/stop the elevator.
