A Stochastic Geometry Analysis of Hybrid Cellular-Adhoc CDMA Networks

Abstract—this paper studies the impact of using multihop wireless adhoc network in conjunction with cellular networks under a probabilistic routing strategy. our objective is to obtain the outage probability of the two-dimensional hybrid cdma network under path loss. in the proposed network the base stations are placed on a regular grid and users are distributed randomly according to a homogeneous poisson point process. to obtain the outage probability of the proposed hybrid network, we study the outage probability of a cellular cdma wireless network on both uplink and downlink as well as the outage probability of a multihop ad hoc cdma network. we validate our analytical expressions via monte carlo simulations. our results demonstrate that in order to improve the performance of a hybrid wireless network with a large density of users, it is beneficial to use multihop ad hoc communication.
