In this paper, we present an extensible and modular NS2 based simulation framework to simulate Wireless Distribution Systems (WDS). A WDS is the interconnection of access points (APs) via wireless links. We point out and clarify some of the shortcomings inherent to the current implementations of the IEEE 802.11 in NS2. We describe then a new design for different IEEE 802.11 models including the WDS component. Our design includes the use of several interfaces per AP and provides a framework for the integration and the study of WDS architectures. We show that using just two interfaces per AP for the WDS nearly doubles the throughput, maintains the sequencing of delivered data frames and improves the average data frame delay.
