This paper proposes RITMC, an asynchronous multichannel receiver-initiated MAC for low-power WSN. Through a comparison with already existing solutions, the RITMC tries to mitigate the message containment and the effect of Idle Listening through an initial recognition mechanism proposed by the A-MAC protocol, in addition to a multichannel mechanism and a more efficient diagnostic. In order to validate the proposed protocol, evaluations were made to the consumption of each node sensor, the network traffic for each link, the latency and the delivery rate of the network in a web application. The results show that the proposed RITMC minimizes energy consumption, besides improving communication and implementation when compared to the analyzed protocols.
