This paper proposes a new method for real-time distributed image acquisition through wireless networks of traffic monitoring cameras. The goal is to provide comprehensive image acquisition in the presence of dynamic disturbances, which obstruct the field of view (FOV) of the cameras. The paper presents a collaborative online algorithm, which (upon FOV loss) identifies an optimized set of cameras that...
A very high speed FSO (free space optics) link has been successfully implemented for purposes of high requirement applications, at the University Campus. An experimental performance evaluation of this link has been carried out at various OSI levels (1, 4, and 7). Several results are presented and discussed.
The bandwidth broker is a management instance inside a PLC system, which has the complete overview about the network topology, the actual reserved bandwidth on each link inside its domain and should ideally have also a real-time view of the available bandwidth on each link. The bandwidth broker acts as an intermediate unit for call setups in a way that a call with ensured quality has to send a signaling...
Internet's rapid growth promoted the evolutoin of network based applications. Since a particular network application has its special requirements for network topology, many different protocols have been introduced over the last couple of years. Most of these protocols overlap and are redundant in function, which results in bad overall performance of the application and the network. This paper presents...
Ethernet passive optical network (EPON) is an access network that delivers essential services of voice, video, and data communications reliably, while at the same time providing expected guarantees of the delivery of those services in terms of defined quality of service measures (QOS). This paper compares performance criteria such as delay, queue size, and packet loss ratio for two dynamic bandwidth...
