Non-saturated and Saturated Throughput Analysis for IEEE 802.11e EDCA
Multi-hop Networks <Abstract> This paper presents first-step analytical expressions of non-saturated and saturated throughput for IEEE 802.11e Enhanced Distributed Channel Access (EDCA) multi-hop string-topology networks. Internal collisions in each node, concurrent transmission collisions among nodes, differences of CWmin and CWmax among access categories (ACs) , and effects of contention zone are considered. By comparisons with simulation results, the validities of analytical expressions are confirmed. |
