Interference analysis at mesh access point considering mesh node activity

Wireless mesh networks have various link types around a mesh access point due to variety of network circumstances. Considering three different link types: star, ad hoc, and hybrid, we analyze the mean interference power at mesh AP according to link types. The effect of the mesh node activity on the mean interference power at mesh access point is also investigated. Through numerical results, it is observed that ad hoc link is highly dependent, star link is independent, and hybrid link is lightly dependent upon the pass loss exponent. In addition, it is shown that the mean interference power at MAP for the ad hoc link is always higher than that for the other links.
