A prioritized Medium Access Control (MAC) grants the right to access to the computer node with the highest priority. Such a protocol was originally created for wireline networks; Controller Area Networks (CAN) is the most known one and it is currently deployed in 700 million units. We are tranferring this idea to the wireless domain and exploring this idea to solve problems in real-time communication and collaborative distributed computing (wireless/line sensor networks and cyber-physical systems).

WiDOM

WiDom is a prioritized MAC protocol for wireless networks

§§§EditSectionPlaceHolder§§§

WiDOM-MBD

WiDom is a prioritized MAC protocol for wireless networks where a single broadcast does not reach all computer nodes.

§§§EditSectionPlaceHolder§§§

WiDOM-MC

We are exploring a prioritized MAC protocol for wireless networks that that offers several channels.

Data Aggregation

Prioritized MAC protocol can be used to efficiently compute aggregated quantities (such as MIN, MAX) of sensor readings.

§§§EditSectionPlaceHolder§§§

Data Dissemination

Prioritized MAC protocol can be used to efficiently disseminate data when the topology is unknown.

WISHES

We are exploring how to use multi-channel capability together with a prioritized MAC protocol to deal with the well-known hidden node problem.
