Abstract—In order to ensure fair access and efficiency of bandwidth usage in wireless integrated networks, resource allocation algorithms should be well designed. In this paper,...
This paper addresses the problem of optimizing the packet transmission schedule in an ad hoc network with end-toend delay constraints. The emphasis is to determine the proper rela...
