The DRMACSN (distributed and receiver‐oriented sensor networks) MAC (medium access control) protocol is a receiver‐oriented protocol, which employs channel load sensing scheme to reduce the delay and the energy consumption in the network. This study presents the queuing analysis of the DRMACSN protocol for DS‐CDMA‐based wireless sensor networks. In this study, a discrete‐time Geom/ G /1 and M / G /1 multiple vacation queuing models that are used to model the behaviour of the DRMACSN MAC protocol are discussed. The study provides the results for the packet delay of the DRMACSN MAC protocol through simulations and the analysis. The results show that a reduced delay performance can be achieved by implementing the channel load blocking technique.
