The high bandwidth demand of Internet applications has recently driven the need of increasing the residential download speed.\r\nA practical solution to the problem is to aggregate the bandwidth of 802.11 access points (APs) backhauls in range. Since 802.11\r\ndevices are usually single radio, the communication to APs on different radio channels requires a time-division multiple access\r\n(TDMA) policy at the client station. With an in-depth experimental analysis and a customized 802.11 driver, in this paper, we\r\nshow that the usage of multi-AP TDMA policy may cause degradation of the TCP throughput and an underutilization of the AP\r\nbackhauls. We then introduce a simple analytical model that accurately predicts the TCP round-trip time (RTT) with a multi-AP\r\nTDMA policy and propose a resource allocation algorithm to reduce the observed TCP RTT with a very low computational cost.\r\nOur proposed scheme runs locally at the client station and improves the aggregate throughput up to 1.5 times compared to stateof-\r\nthe-art allocations.We finally show that the throughput achieved by our algorithm is very close to the theoretical upper bound\r\nin key simulation scenarios.
