Connectivity Analysis in Wireless Ad Hoc Network Based on Interference and Fading Channel

Abstract:

Connectivity is the fundamental of the Ad Hoc wireless network for end to end data transmissions. It becomes difficult to keep the connectivity when uncertain features increase, such as fading channels and interference in the network. Based on the theory of stochastic geometry, a SIR model is used to calculate the link probability between nodes. We derive a tight explicit expression for the connectivity probability in the present of Rayleigh fading and interference. According to this expression, we can optimize network topology efficiently. Simulation results validate the accuracy of our conclusion.
