Internet protocol (IP) is emerging as a ubiquitous protocol for communications and applications. IP-based services aims to provide consumers anytime-anywhere access to content over range of electronic devices and to integrate services & content, to tie them together. This paper presents an overview of various network architectures and their evolution to include an all IP based infrastructure fuelled...
Ensuring a seamless connection when users are moving across radio cells is essential to guarantee a high communication quality. In this paper, performance of TCP during the handover in a Long Term Evolution (LTE) network is investigated. Specifically, mobile users with high bit rates TCP services are considered, and the impacts of the intra LTE handover over their perceived throughput are studied...
This paper provides a technological overview of the system architecture evolution (SAE) of LTE networks. The target of this overview is to provide a basic knowledge on 4G cellular network structure, entities responsibilities and protocol-stack. The overview is mainly based on the relevant 3GPP standards and on Chapter 3 of the book "LTE for UMTS: OFDMA and SC-FDMA based radio access" edited...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
