Transporting voice over IP, instead of traditional CS voice, is a necessary prerequisite for an all IP network. Among the hurdles that need to be overcome are the QoS demands of VoIP, which comprise timely and error free delivery of comparatively low rate packet streams. One way to provide the necessary QoS for VoIP is some admission control strategy, where an incoming connection that cannot have...
Design of radio resource management (RRM) protocols in wireless networks plays a key role in the system's performance. By handling different service classes, RRM protocols must find out a trade off between the Quality of Service (QoS) requirements of real time applications and non-real time applications as well as between users and Service Providers expectations. In the current paper, Traffic Management...
This work proposes a novel routing algorithm for transparent optical networks, which is based on the ant colony optimization (ACO) meta-heuristics. It takes into consideration the bit error rate (BER) of the connections that is derived from amplified spontaneous emission (ASE) noise accumulated along the lightpath. We implement a call admission control (CAC) to verify if a connection meets the following...
