+ | Abstract: Cooperation in wireless networks results when nodes exploit the broadcast nature of the wireless medium | ||
+ | and use their resources to mutually enhance transmissions. It is assumed in general that all network nodes are | ||
+ | willing to cooperate. However, when self interested and rational nodes are allowed to cooperate, it is necessary | ||
+ | to examine whether the cooperation of all users can be taken for granted. There are two major disincentives for | ||
+ | cooperation in a typical network; cost of cooperating and insufficient gains from cooperation. In this talk, I | ||
+ | discuss the problem of transmitter cooperation over a multiple access channel. Using tools from cooperative game | ||
+ | theory, I will show whether the grand coalition forms and if so the scenarios in which it is stable and how stability can | ||
+ | be enforced. I will then talk about some recent work on its dual problem, receiver cooperation over a broadcast channel, | ||
+ | and discuss some of the similarities and differences between the two scenarios. | ||
