Low power consumption Intelligent Local Avoided Collision (iLAC) MAC protocol for WLAN

Mobile wireless communication systems aim at using battery energy efficiently. One of the main source of depleting precious battery of wireless handheld devices is failure frame transmissions due to collision. This paper provides a detailed analysis of the power consumption of newly introduced MAC protocol called Intelligent Local Avoided Collision (iLAC). Analytical solution confirms the correctness of this solution and simulations with different types of Wireless LAN 802.11b cards show that the proposed algorithm is able to significantly reduce the wasteful energy in colliding transmissions.
