Claim:
1. A method for communicating in a contention-based network, comprising: determining, by the transmitting node, a first time point for monitoring a back off time period, the first time point occurring in a time period prior to an expected time point for receiving a payload; monitoring, by the transmitting node at the first time point, the back off time period; sending, by the transmitting node at a second time point prior to receiving a payload, a request to reserve a channel for transmission of the payload; receiving, by the transmitting node prior to receiving the payload, a grant sent from a receiving node to confirm availability of the receiving node to receive the payload over the channel; receiving the payload at the transmitting node; sending, by the transmitting node, the payload over the channel at a third time point; calculating, by the transmitting node, a time difference between when the grant is received and when the payload is received; comparing, by the transmitting node, the time difference to a threshold; and adjusting, by the transmitting node, the time period between the first time point and the expected time point for receiving the payload based on the comparison.
