Existing video streaming protocols get poor QoE (Quality of Experience) especially when network bandwidth is drastically fluctuated due to handoff events over heterogeneous networks where they provide different bandwidths and network conditions. This paper proposes a novel QoE guaranteed mobile video streaming scheme over heterogeneous wireless networks: MOSQUITO. MOSQUITO can dynamically adjust streaming...
A framework that aims to best utilize the mobile network resources for video applications is presented in this paper. The main contribution of the work proposed is the QoE-driven optimization method that can maintain a desired trade-off between fairness and efficiency in allocating resources in terms of data rates to video streaming users in LTE networks. This method is concerned with the control...
In recent years, the monitoring of End-to-End protocols from inside the mobile data network has become a powerful tool to gain insight into subscriber specific information on usage behavior and quality of experience. With the advent of big data in mobile networks, the power of statistical data analysis can now be utilized in order to answer so far untreatable questions both in the area of network...
Service continuity between EGPRS (2G) and WCDMA (3G) systems has been identified as one key research item recently. Measurement from live cellular networks indicate that outage time for packet switched traffic during intersystem handovers are too long going up to one minute in some cases. In this article we analyze intersystem handover latency across 3G and 2G wireless networks. The inter-system handover...
