| + | 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. | ||

| + | Bio: Srinivas Yerramalli is a Ph D candidate at USC working with Prof. Urbashi Mitra. Prior to this he obtained his B.Tech | ||
| + | degree from the International Institute for Information Technology in Hyderabad, India. His research interests lie in the | ||
| + | general areas of wireless communications, signal processing and optimization, and his PhD work has been focused towards high | ||
| + | speed underwater acoustic communications. | ||
