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.

最近，干扰限制的临时网络引起了对无线网络社区的兴趣越来越多。事实证明，网络中节点的空间配置和中等访问策略是主要问题，因为它们正在确定网络中的干扰情况。这是因为，与时间和频率的干扰相反，无法设计空间中的干扰泄漏[3]。这是实际的空间配置显着影响网络性能。这一事实导致了称为“用于分析和无线临时网络的随机几何形状和设计”的研究框架[1]。在这里，空间过程用于对节点的随机位置进行建模。因此，来自未知空间配置的自由度被选择的空间模型所取代。该研究领域的结果主要假设一个简化的网络模型，其中中等访问是不协调的，并且传输是非合作的。该提案旨在通过研究中等访问的协调来避免使用中等干扰和合作的过度干扰和合作来扩展该研究领域，以增加干扰和通过网络编码以增加干扰范围内的覆盖范围，并通过干扰范围内的AD AD HOCENTECTIMENTIMPIMIMPIM-AD hocture网络进行。在该项目中，必须通过随机几何形状对协调和合作在干扰限制的临时网络中的影响进行建模和分析，因为不得假定没有具体的网络拓扑，因此可以实现协调和合作策略的无处不在基准。
