Abstract
A method for providing wireless communication between a source node and a destination node in a wireless network wherein the wireless network uses a time division multiple access (TDMA) protocol. One or more dedicated TDMA transaction timeslots are arranged in a superframe. The superframe includes at least one dedicated transaction slot forming a hybrid protocol with two or more shared transaction slots per superframe. The method is of particular advantage when practised with a WirelessHART protocol wireless sensor network and when used for monitoring and control equipment and processes in an industrial installation. A computer program, and a wireless node and a wireless network using the inventive method are also disclosed.
