In this paper we introduced a new MAC sub-layer protocol for multi-hop Real-Time Wireless Sensor Networks (RTWSNs). This protocol makes it possible to transmit time-constrained data with given priorities and end-to-end delays. Such data are needed in multimedia applications implemented in RTWSNs. We carried out a comprehensive analysis of our protocol. Moreover, we included in this protocol a topology control mechanism which allowed us to determine the critical transmitting range. We simulated and analysed the performance measures of our protocol.
