The Wireless Dominance Protocol (WiDom), is a novel medium access control protocol designed for wireless systems to efficiently schedule sporadic message streams with real-time requirements. This protocol gives the wireless channel a similar behavior as a Controller Area Network (CAN) bus. It is prioritized and this can be achieved even without having the ability to listen and transmit simultaneously. WiDom is useful not only to provide timeliness guarantees, but it can also be a building block for certain distributed calculations. This is a crucial asset for addressing problems in future Large-Scale Cyber-Physical Systems.
Recently, it was demonstrated that highly scalable aggregate computations in wireless networks are possible by exploiting WiDom. This was achieved by (i) building a new wireless hardware platform with appropriate characteristics to make wireless dominance-based MAC protocols efficient, (ii) implementing dominance-based MAC protocols on this platform, (iii) implementing distributed algorithms for aggregate computations (MIN,MAX, Interpolation) using the new implementation of the dominance-based MAC protocol and (iv) performing experiments that prove that such highly scalable aggregate computations in wireless networks are possible.
