When a content provider (CP) provides peer-to-peer live streaming service, routing decisions based on the knowledge of underlay traffic could lead to much better performance (such as user delay). On the other hand, if the Internet Service Providers (ISPs) provide underlay traffic information to the CP, their overall network cost due to routing inefficiencies could be reduced. There is hence incentive...
Expectation and requirements for future wireless communication systems continue to grow and evolve. Thus, 3GPP has considered LTE/SAE to ensure its competitiveness in the future. In LTE/SAE, one of the recurring problems is dimensioning and testing. Modeling is an effective way to solve the problem because model is easy to generate test scenarios and inexpensive in changing test configurations and...
The wide usage of IEEE 802.11 based wireless LANs have led to lots of interest in providing quality of service (QoS) guarantees in such networks. 802.11e is the QoS variant of the 802.11 family of protocols. But it has a twofold drawback. First, QoS requirements relevant to a given application are always fulfilled by the "statically" associated priority. Second, resource requests of the...
Wireless sensor networks (WSNs) are becoming a viable tool for many monitoring applications. In many cases these applications may be of critical nature where the transmitting of vital information from sensors to base station or sink is crucial, and data loss cannot be tolerated. As a result, the information transmission of wireless sensor networks has various different requirements in performance,...
