Sinr-based slot reuse algorithm for multi-channel wireless sensor networks

EURASIP Journal on Wireless Communications and Networking
Multi-channel technology can effectively eliminate wireless interference. The algorithms proposed for multi-channel sensor networks usually assume that sufficient channels are available to enable interference-free parallel transmission.
