Описание:The network performance can be evaluated by parameters such as new call blocking probability, handoff call blocking probability and bandwidth utilization. The system makes use of a heuristic mechanism that determines the available bandwidth for the new calls according to some parameter values of the system. The results show improvements in all parameters. Thus, in cellular networks the call admission control greatly influences the system performance because it determines the bandwidth use of the CBSs. In the cellular base station (CBS), the bandwidth availability is limited. The bandwidth borrowing is applied to the cell ongoing calls until the minimum levels for each type are met. The recent growth in traffic loads in cellular networks has seen the need for a better use of system resources as its expansion is expensive. The algorithm was applied to the bandwidths and characteristics of a 3G network. This work proposes a call admission control that carries out the bandwidth borrowing when a call arrives and there is not enough bandwidth. It was also applied to a GSM/GPRS (global system for mobile communications/ general packet radio service).

Windows API Tutorials

It then goes back to watchful sleep. Concurrently, Windows retrieves our WM_FOLDER_CHANGE message from the message queue and sends it to the Windows Procedure of the sink window. More about that in a moment. UINT const WM_FOLDER_CHANGE = WM_USER; void FolderWatcher::Loop () {  for (;;) {   // Wait for change notification   DWORD waitStatus = WaitForSingleObject (_notifySource, INFINITE);   if (WAIT_OBJECT_0 == waitStatus) {    // If folder changed    if (_isDying) return;    PostMessage (_hwndNotifySink, WM_FOLDER_CHANGE, 0, (LPARAM) _folder);    // Continue change notification    if (!_notifySource.ContinueNotification ()) {     // Error: Continuation failed     return;    }   } else {    // Error: Wait failed    return;   }  } } So here what happens in the Windows Procedure in response to our special message: we call the Controller's method OnFolderChange. This method can do anything we want. In the Explorer it refreshes the display of the folder we are watching. In our example it just pops up a simple message box ...»

Topology Control and Pointing in Free Space Optical Networks. Concepts and Methods
In order to be useful, FSO communication must deal with the following fundamental problems: (1) How to quickly and precisely establish and maintain optical links between nodes in the network? (Pointing, Tracking, and Acquisition); (2) How to optimize network performance in terms of network cost and congestion? (Topology Optimization); (3) How to respond autonomously to possible network performance degradation due to link loss or sudden changes in traffic demands? (Topology Control). This book, therefore, provides solutions to the above problems with both a hardware approach for developing self-organized pointing and a software approach for developing accurate heuristic algorithms for topology optimization in bi-connected FSO networks.
