Spider: Improving Mobile Networking With Concurrent Wi-Fi Connections
The authors present an in-depth analysis of the performance of attempting concurrent AP connections from highly mo-bile clients. Previous solutions for concurrent Wi-Fi is limited to stationary wireless clients and do not take into account a myriad of mobile factors. Through an analytical model, optimization framework, and numerous outdoor experiments, they show that connection duration, AP response times, channel scheduling, available and offered bandwidth, node speed, and dhcp joins all affect performance. Building on these results, they design, implement, and evaluate a system, Spider that establishes and maintains concurrent connections to 802.11 APs in a mobile environment.
