This paper presents a contention adaptation (CA) mechanism to improve the energy efficiency in IEEE 802.11e EDCA. By suspending some transmissions, the proposed EDCA/CA can reduce the number of collisions. Because unnecessary retransmissions are eliminated, the energy consumption is reduced. Extensive simulations have been performed to demonstrate the performance of the proposed EDCA/CA. The results show that EDCA/CA can reduce the energy consumption significantly. It reduces frame delay as… CONTINUE READING
