Multiple Access with Collision Avoidance for Wireless ( MACAW) [1] is a slotted medium access control (MAC) protocol widely used in ad hoc networks. [2] Furthermore, it is the foundation of many other MAC protocols used in wireless sensor networks (WSN). [2] The IEEE 802.11 RTS/CTS mechanism is adopted from this protocol.
