Abstract—Recently, Raspberry Pi has become popular around the world due to the low cost, small size, yet powerful computing ability. Being equipped with an IEEE 802.11n wireless network interface card (NIC), it can be used as a software access-point (AP) for the wireless local-area network (WLAN). Previously, we studied the channel bonding (CB) implementation using an external wireless NIC for Raspberry Pi AP, and the throughput estimation model for concurrent communications of multiple links with up to three APs under 11 and 13 partially overlapping channels (POCs). In this paper, we propose the network configuration optimization algorithm for WLAN with three Raspberry Pi APs. Using the throughput estimation model, it determines the use of CB and non-CB, the channel assignment, and the associated hosts for each AP that maximizes the estimated total throughput. The effectiveness of this algorithm is verified through simulations using the WIMNET simulator and through testbed experiments in uniform, non-uniform, and two-crowded APs topologies.
