Abstract

This paper focuses on the aggregation mechanisms of MAC and physical layer to improve the performances of 802.11n network. Based on the concept of physical layer aggregation, an improved MRA algorithm called IMRA is proposed. Analysis of system efficiency and simulation on IMRA reveal that the system efficiency of IMRA is improved compared to PSMP mechanism, and it is suitable to support real time services.
