... motivate the need for a fair MAC protocol, we first analyze a hybrid -MAC scheme which mimics the 802.11e MAC in every essential respect. The analyti- cal expressions attained for throughput and ... absence of LP traffic. Before we delve into the details of our fair MAC scheme, it is worthwhile to examine the existing IEEE 802.11e MAC protocol. 3.1 Examining IEEE 802.11e MAC protocol To enhance ... model for our 802.11e-like Hybrid -MAC and derive throughput and delay expres- sions for the MAC along with MATLAB simulation results. In Section 3, we present and discuss our pro- posed MAC scheme....

This article proposes a novel energy efficient MAC protocol for multiple ... cycle of the proposed MAC pro- tocol were simulated and compared with B -MAC and star topology TDMA protocol. The results showed that the proposed MAC protocol outperforms B -MAC and the star topology ... overhead. Many energy effi- cient MAC protocols h ave been proposed in prior works. B -MAC [5], S -MAC [6], T -MAC [ 10] are exam- ples of typical contention-based MAC protocols. They offer the advantages...
