In wireless networks, modeling of the physical layer behavior is an important yet difficult task. Modeling and estimating wireless interference is receiving great attention, and is crucial in a wireless network performance study. The physical layer capture, preamble detection, and carrier sense threshold are three key components that play important roles in successful frame reception in the presence...
Wireless mesh networks aim to provide high-speed Internet service without costly network infrastructure deployment and maintenance. The main obstacle in achieving high-capacity wireless mesh networks is interference between the mesh links. In this article, we analyze the carrier sensing and interference relations between two wireless links and measure the impact of these relations on link capacity...
We analyze the carrier sensing and interference relations between the two wireless links and measure the impact of these relations on link capacity in two indoor 802.11a mesh network testbeds. We show that asymmetric carrier sensing and/or interference relations happen frequently in wireless networks; these asymmetric relations affect not only the level of performance degradation, but also the fairness...
