Interference Calculus and Resource Allocation
The optimal resource allocation in wireless networks depends on many parameters and is usually a very complex problem. The observed interference of a user in a network is modeled through the concept of interference functions. However, it is also necessary to develop a framework for the utility modeling. From the practical point of view, it is interesting to characterize all concave and convex resource allocation problems. Furthermore, it is important to characterize the supportable quality of the service region in a multi-user wireless system. The results form the basis for:
- Efficient resource allocation schemas, e. g. power control
- Convergence speed of algorthims
- Complexity
- Fairness
- Utility optimization
