For the multiuser resource allo-cation problem at hand, a global cross-layer optimization CLO problem is formulated: maximize the user-perceived quality by tuning the served data rate on[r]

The main contribution of this work includes the following: _1 possible architecture for cross-layer optimization which_ provides a potential solution of joint optimization of the physica[r]

By using this method, the resource allocation and traffic scheduling can be formulated into a cross-layer optimization problem under the transmission rate constraints, which is convex fort[r]

This is an obvious contrast to the popular store-and-forward routing scheme implemented in most current networks where the intermediate nodes just simply forward the received data. This new transmission paradigm offers several benefits, includin[r]

requests a suitable number of retransmissions from the set of colliding users. Thereupon, signal processing lets the base station separate the signals from all the colliding users.
As another example, consider the problem of joint scheduling and power control in wireless ad-hoc networks. Example[r]
