Abstract
In ubiquitous environments, the mobility of mobile nodes has been increasing. Due to the increased mobility for mobile nodes, we experience co-channel or adjacent interference very frequently. These interference phenomena are becoming a big issue because they represent significant performance degradation of the wireless network. In this paper, we conducted several experiments outside in order to validate the co-channel interference phenomenon. As we measured network performance in an outdoor environment without existing Wi-Fi signal, we did analysis about the performance impact to the TCP layer in a wireless ad-hoc network. Our work contributes to a more clear understanding for error propagation to the upper layer of the network stack when co-channel interference occurs in an ad-hoc network and propose a theoretical maximum throughput considering error rate in the data link layer and TCP layer.
