Binary TDMA Scheduler by Means of Egyptian Fractions for Real-Time WSNs on TMotes
In Wireless Sensor Networks (WSNs), the user should not be bothered with configuring the network, depending on the kind of sensors that he/she is using. It should only be a matter of deploying the sensors and they should do the necessary effort to construct a network. Since most of these networks use low power devices, the energy consumption is vital. The most suited medium access method in order to waste as few energy as possible, is Time Division Multiple Access (TDMA). TDMA has however the reputation of being a rigid access method. In this paper, the authors present a TDMA access method for passive sensors, i.e. sensors are constant bitrate sources.
