Admission control plays an important role in providing the desired Quality of Service (QoS) in wireless networks. It depends on precise estimates of bandwidth available in the network and the bandwidth required by new flows. Estimating these parameters in wireless networks is challenging due to the shared and open nature of the wireless channel. Resources sharing in wireless links imposes a number...
NEWSKY is a project aiming at the integration of various communication links into an all-IP based network. This network shall be based on IPv6 and commercial of the shelf products (COTS). Technical work packages have defined solutions for quality of service, mobility, inter- and intra- network handover, and security. In order to validate the derived concepts a realistic topology has been built which...
This paper aims at adding quality of services (QoS) extensions to the associativity based routing (ABR). The performance analysis of the ABR with QOS support is the same as ABR except for more computation on the intermediate nodes to comply with the QOS requirements and the size of the control messages will be varying. But the total number of operations performed and total number of messages exchange...
Integration of disparate access networks in Next Generation Mobile Networks (NGMN) introduces several implementation issues to the quality of service (QoS) and security aspects. The large amount of generated traffic in the network imposes scalability issue which significantly affects the performance of traffic measurement and anomaly detection. While the use of sampling is capable of addressing the...
There are many fields at where ad hoc networks are used, but applications like mission critical and commercial production or broadcasting which mostly contain real time audio and video streams and require absolute end to end guarantee for QoS. The key attribute these applications for guarantying for QoS is, they need routing path for connectivity like virtual leased line that is very difficult in...
