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).
§§§EditSectionPlaceHolder§§§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.
§§§EditSectionPlaceHolder§§§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.
§§§EditSectionPlaceHolder§§§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.
