Multi-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey
Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...

متن کاملDistributed Channel Allocation Scheme for Wireless Sensor Networks
This paper introduces a distributed channel assignment scheme (DCA) for wireless sensor networks. Recent developments in sensor technology, as seen in Berkeley's Mica2 Mote, Rockwell's WINS nodes and the IEEE 802.15.4 Zigbee, have enabled support for single-transceiver, multi-channel communication. DCA exploits this capability by assigning optimally minimum channels in a distributed manner in o...
متن کاملDistributed Channel Allocation Algorithms for Wireless Sensor Networks
Interference between concurrent transmissions can cause severe performance degradation in wireless sensor networks (WSNs). While multiple channels available in WSN technology such as IEEE 802.15.4 can be exploited to mitigate interference, channel allocation can have a significant impact on the performance of multi-channel communication. This paper proposes a set of distributed algorithms for n...
متن کاملInference-Based Distributed Channel Allocation in Wireless Sensor Networks
Interference-aware resource allocation of time slots and frequency channels in single-antenna, halfduplex radio wireless sensor networks (WSN) is challenging. Devising distributed algorithms for such task further complicates the problem. This work studies WSN joint time and frequency channel allocation for a given routing tree, such that: a) allocation is performed in a fully distributed way, i...
