Recently, interference-limited ad hoc networks gained increasing interest in the wireless network community. It turns out that the spatial configuration of nodes in the network and the medium access strategy are of primary concern, since they are determining the interference situation in the network. This is because, in contrast to interference in time and frequency, interference leakage in space cannot be engineered [3]. Thus, the actual spatial configuration significantly influences network performance.This fact resulted in the research framework called “Stochastic geometry for the analysis and the design of wireless ad hoc networks” [1]. Here, spatial processes are used to model the random locations of nodes. By this, the degree of freedom coming from the unknown spatial configuration is replaced by the choice of an appropriate spatial model. Results in this research field were mainly assuming a simplified network model, in which medium access is uncoordinated and transmissions are noncooperative.This proposal aims at extending this research field by studying coordination of medium access to avoid excessive interference and cooperation using relaying or network coding in order to increase coverage and throughput in interference-limited ad hoc networks. In this project, it is mandatory to model and to analyze the effects of coordination and cooperation in interference-limited ad hoc networks by means of stochastic geometry, since no specific network topology must be assumed and, hence, ubiquitous benchmarking of coordination and cooperation strategies becomes possible.
