Expected interference in wireless networks with geometric path loss: a closed-form approximation
Hermann Simon Lichte, Stefan Valentin, Holger Karl · IEEE Communications Letters · 2010
In this letter, we derive 2¿¿P/((¿ - 2)g¿ - 2) as a closed-form approximation of the expected interference around a receiver in wireless networks. We use a geometric path loss model, assume that nodes are randomly distributed, and that only nodes outside a guard zone around the receiver simultaneously transmit. The derived solution depends on the path loss exponent ¿, node density ¿, transmission power per node P, and the radius g of the guard zone. The simplicity of this solution makes it widely applicable in wireless network analysis.
