Topic

Rethinking the Interference Modeling Method for Random Wireless Networks

Abstract

Due to the broadcast nature of wireless communications, interference modeling is one of the key components of studies for wireless networks. Currently, almost all of the interference- related analyses are following the classic "discrete-style" modeling method, i.e., obtaining each concurrent transmitter's impact on a tagged observation point individually, and adding them together. To utilize the discrete-style method, the information of: 1) the number of coexisting transmitters in the network, and 2) the distance (or distance distribution) between all the interferers and the tagged observation point, should be acquired. However, neither of them is easy (or even feasible) to be obtained in the random wireless network scenario. In this talk, a Power Emission Density-based interference modeling method, which borrows the area-point equivalence idea from physics and makes use of the basic features of the Exclusive Region created by each communicating pair, will be introduced. By utilizing the new method, the traditional discrete-style calculation can be replaced with a concise integration over the entire network area, which could effectively reduce the complexity of interference modeling for random wireless networks. Moreover, some applications of the new method will also be described.
