Permutation routing is the particular case . = . = 1. In the .-central routing problem, all nodes at distance at most . from a fixed node . want to send a packet to

In this chapter, we summarize some recent advances in applying mathematical optimization models for solving planning problems arising in placing access points

The goal of the first problem is to perform broadcasting from a given source while minimizing the overall energy required for communication. The second problem refers to the choice of activa

The interference constraints limit the possibility of simultaneous data communication of nodes to the same region of the network. The survey focuses on two interference models, the g

We give mathematical evidence showing that our performance is asymptotically tight. We also place ourselves in the WiFi and WiMAX frameworks, and discuss experimental results showing acollision reduction of 14% to 21

Branch-and-Cut Techniques for Solving Realistic Two-Layer Network Design Problemsd node hardware of both network layers such that traffic demands can be realized via grooming and a survivable routing. We present a mixed-integer programming formulation for a predefined set of admissible logical links that takes many practical side constraints into account, including node hardware
