Multi-channel MAC Protocols for Wireless Sensor Networks
b'Speaker:\\n\\nDr. C. Cano\\n\\n\\nAbstract:\\n\\nWireless Sensor Networks (WSNs) are networks formed by\\rhighly constrained devices that communicate measured environmental\\rdata using low-power wireless transmissions. The increase of spectrum\\rutilization in non-licensed bands along with the reduced power used by\\rthese nodes is expected to cause high interference problems in WSNs.\\rTherefore, the design of new dynamic spectrum access techniques\\rspecifically tailored to these networks plays an important role for\\rtheir future development. In this talk the main challenges of dynamic\\rspectrum access in WSNs will be described and a first approach to\\rcoordinate sensor nodes will be presented.'
