چکیده

We consider a realistic model of wireless network where nodes are dispatched in an infinite map with uniform distribution. Signal decays with distance according to attenuation factor α. At any time we assume that the distribution of emitters is λ per square unit area. From the explicit formula of the laplace transform of received signal we derive the explicit formula for the information rate received by a random node which is α2 (log 2) −1 per Hertz. We generalize to any-dimension network maps.

Les signaux décroissent avec la distance avec un facteur d’atténuation α. A tout moment nous supposons que la distribution des emetteurs instantanés est de λ par carré unité. De l’expression explicite de la transformée de Laplace de la distribution du signal reçu nous dérivons une formule explicite du débit d’information reçue par un nœud arbitraire qui est α2 (log 2) −1. Nous généralisons pour des cartes dans des espaces vectoriels de dimension quelconque.

Network Coding Capacity of Random Wireless Networks under a SINR Model

Previous work on network coding capacity for random wired and wireless networks have focused on the case where the capacities of links in the network are independent. In this paper, we consider a more realistic model, where wireless networks are modelled by random geometric graphs with interference and noise. In this model, the capacities of links are not independent. By employing coupling and ...

Stochastic geometry modeling of spatial wireless communication networks — beyond the Poisson assumption

There is a need for simple, yet realistic models for communication network architectures capturing the spatial distribution of the elements of the network and having a limited number of parameters. This can be obtained via probabilistic modeling based on point processes and stochastic geometry. The probabilistic setting reflects the network variability in time and space, this is particularly re...
