An Analytical Tool for Dimensioning Wireless Multihop Networks with Traffic and Interference Combined

The tradeoff between maximizing the number of transmissions and reducing total interference is the main problem about dimensioning wireless multihop networks. The estimation of how many transmissions the network can support ensuring a quality of service for its users is a difficult task due to two central aspects: the wireless medium and the multihop nature of transmissions. In this paper, we derive an analytical solution for the calculation of outage probability in a wireless multihop network that considers both aspects jointly. The outage probability is defined as the probability of a transmission between two nodes is not established because no available channels along a specific route or the signal-to-interference ratio is below a specified threshold. The proposed solution is compared with simulations, and an excellent agreement is attained.
