TCP Performance Optimization for Handover Management for LTE Satellite/Terrestrial Hybrid Networks

Résumé

Long Term Evolution tends to become the next generation of civil security networks. In order to meet the safety user requirements, preference is given to an integrated satellite and terrestrial architecture. It provides a widespread connectivity built on the large satellite coverage. In this paper, we focus our works on the real behavior of TCP protocols, implemented in on-the-shelf devices, during a handover within the hybrid architecture. We aim to improve an optimized handover procedure by taking into account the real implementations that differ from simulation tools and RFCs. In order to highlight and solve the problematic behaviors of TCP protocol due to a S1 handover with an SGW and MME relocation, a test is set up with Linux virtual machines for TCP application linked to a NS3 LTE network simulator.
