Abstract:

First in first out (FIFO) queue is currently used in media access control (MAC) protocols for mobile ad hoc networks. As a result, the head-of-line blocking might be happened. Based on power controlled multiple access protocol (PCMA), a MAC protocol without head-of-line blocking (PCMA+) was proposed. Simulation shows that, compared with PCMA in which FIFO queue is adopted, a good improvement will be obtained when in use of PCMA+.

Key words: media access control, mobile ad hoc networks, head-of-line blocking, power control
