The popularity of video sharing over social networks is straining service providers to maintain high quality of service. With the introduction of live video streaming over social networks, video sharing is truly becoming social and real time. However, existing video distribution architecture, split across content providers and mobile network operators, cannot leverage crossprovider information. We...
We study a novel scheme to manage networks with heterogeneous traffic efficiently under resource crunch. We consider different types of revenue models for different service classes. We show that degradation of services and redistribution of resources while satisfying QoS under resource crunch can improve both availability and revenue.
The 3rd Generation Partnership Project — Long Term Evolution (3GPP-LTE) is the best choice for multimedia data transmission in demanding situation. The 3GPP LTE provides high data transmission rate between the User Equipment (UE) and Evolved Node B (eNB) with lower latency and better throughput. However, with the advancement and increasing traffic of data load, it is necessary to have data scheduling...
We propose a new channel rate and queue state adaptive time resource allocation heuristic for the base stations in a multiuser wireless access scenario. Motivation of the scheme is derived through the effective capacity concept. Our proposed strategy accounts for fairness and quality-of-service (QoS) of the system on per frame basis. Our results show that the proposed scheme benefits the users with...
All wireless systems require the precise timing synchronization to satisfy the higher quality of service (QoS) requirements. Particularly, timing synchronization between base stations (BSs) during soft handover is required to increase the diversity gain of soft handover. Current timing synchronization protocol (e.g. IEEE1588, GPS) updates the synchronization at fixed time duration and it causes the...
