The authors present the design and implementation of MCC, the first high-rate multi-channel time-scheduled protocol for fair, real-time data collection in Wireless Sensor Networks. MCC incorporates sophisticated mechanisms for balanced routing tree formation, multiple frequency channel allocation and globally synchronized TDMA scheduling. Through systematic experiments with real WSN hardware(Tmote Sky), they first identify the maximum possible throughput for many-to-one (convergecast) data collection in sensor networks. They show through a comprehensive experimental evaluation on the Tutornet experimental testbed that MCC can achieve close to the maximum possible network throughput for collection in wireless sensor networks with very low synchronization overhead.
