Wireless Link SNR Mapping Onto An Indoor Testbed

To facilitate a broad range of experimental research on novel protocols and application concepts, we employ an indoor wireless testbed to emulate the performance of the real-world networks. A fundamental issue for emulation is the replication of communication links of specified quality. In particular, we need to replicate on the testbed, for every link in the real world, a communication link whose received signal-to-interference-and-noise-ratio (SINR) matches the corresponding link signal-to-noise-ratio (SNR). In this paper, we focus on the downlink SNR mapping associated with a network with a single access point (AP). Four indoor wireless propagation models (commercial buildings with/without line of sight path and residential buildings with/without line of sight path) and two types of geometric distributions (uniform distribution inside a circular cell and uniform distribution along a line) have been investigated. Based on the characteristics of the indoor testbed, we propose a mappi...
