Abstract

This report introduces MacZ, a hardware-independent MAC layer with QoS capabilities. The focus is on the basic layer of MacZ that provides common services, in particular distributed multihop synchronization, signaling of alert messages and conflict detection and resolution services. The intended application domain for MacZ is within Ambient Intelligence, where small, energy-efficient, reliable and adaptive communication networks are required. Besides the hardware independent description, a mapping to an existing hardware using an IEEE 802.15.4 compliant transceiver chipset is performed. MacZ consists of several components that model distinct protocol functionalities. The components are specified as micro protocols in SDL and composed using a micro protocol framework.
