A multichannel hybrid MAC protocol for wireless sensor networks
XI Yuan-hao · The Internet of Things · 2013
In order to improve wireless sensor networks throughput and reduce time delay, a multichannel MAC protocol called MCHMAC is designed, which use contention based and scheduled based hybrid access mechanism to transmit information, the energy is saved by dynamically adjusts the active and sleep time of nodes. MCHMAC use channel state estimation algorithm to evaluate channel, it also proposes to find a best channel by a channel schedule table for nodes. Experimental results show that this protocol improves the throughput and reduces the network delay.
