Performance Improvement of Media Point Network using the Inter Access Point Protocol according to IEEE 802.11f

This paper demonstrates how the Inter Access Point Protocol (lAPP) can be used to improve the performance in a Media Point systems. The Media Point system provides high-volume personalized data services within WLAN hotspots with discontiguous coverage areas. Based on our experimental performance evaluation, we present three mechanism to improve performance. First, lAPP allows to reduce the required signalling by means of an extended EAP-TLS authentication procedure. Second, IAPP can be used to trigger an abbreviated DHCP procedure. Third, we present a pre-caching mechanism for the hierarchically structured media point network. In the latter two mechanisms the role of lAPP is to provide the terminal MAC address to other Media Point control nodes.
