Optimization Channel Assignment Method for Maximum Throughput under Communication and Positioning Requirements

In this paper, we first discuss a throughput estimate method based on RTS/CTS, and then propose a channel assignment method that could achieve two goals: (a) the maximum throughput of overall network can be guaranteed and (b) terminals can be located in our system. Traditionally, channel assignment is used to mitigate interference for communication. In the area of positioning, to meet the requirement of highly-accurate positioning, wireless Access Points (APs) are always assigned to a single channel. In other words, although mutual interference occurs seriously, channel assignment is not discussed in this area. To the best of our knowledge, we are the first to propose a tradeoff method that gives considerations to communication and location simultaneously. To confirm its effectiveness, we evaluate our approach by simulation. The results illustrate that the throughput of our channel assignment method is higher than other methods.
