This paper addresses the distributed power adaptation (DPA) problem on the downlink for wireless cellular networks. As a consequence of uncoordinated local scheduling decisions in classical networks, the base stations produce mutual uncontrolled interference on their co-channel users. This interference is of a variable nature, and is hardly predictable, which leads to suboptimal scheduling and power...
The signalling subsystem is the most expensive and complex element in cellular networks. Today's networks use signalling mechanisms whose design builds on more than 20 years of the operational expertise. Despite this, the signalling subsystem of all mobile network standards remains vulnerable to failures of equipment and to sharp increases in offered load caused by unanticipated traffic patterns....
In this paper, we study the communication overhead of gossip-based information dissemination algorithms. Among basic variants of gossip algorithm push is most efficient in the early rounds while, in contrast, pull becomes more efficient in the later rounds. Therefore, a cost-efficient gossip algorithm needs to combine the advantages of push and pull algorithms. One possible approach is to begin with...
