MAC Layer Impact on the Performance of Real-Time Cooperative Positioning
This paper analyzes the impact of Medium Access Control (MAC) layer on the performance of real-time cooperative positioning in ad-hoc mobile wireless networks. The probability mass function (pmf) of the latency introduced by the MAC layer is here derived to assess the influence of MAC parameters on the latency and then operate on those to improve the positioning performance while reducing the number of position estimation iterations. Now-a-days, in many wireless applications the information collected or communicated by a wireless node is useless if this is not associated to the node's position. These applications rely on positioning techniques which infer the position by a two-step process.
