particular, cross-layer optimization techniques have been under intense research as primary strategies for adaptation to dynamic channel conditions, since they permit to improve the quality of experienceby optimizing the network architectures across traditional OSI stack layers. The main issue to be faced when adopting a cross- how DVB-T2 transmission can be optimized for improved mobile broadcast reception. We investigate cross-layer optimization techniques with a focus on the transport of scalable video (SVC) streams over DVB-T2 Physical Layer Pipes (PLP). Throughout the paper, we propose different optimization options and verify their utility. 1.Introduction

These optimization techniques are based on a few fundamental principles, such as reduction of the number of signaling messages during the basic operations, minimizing the traversal distance of the data, reduction of data and signaling overhead, minimization of lookup cost, caching, parallelization of sequential handoff operations, proactive operations, cross‐layer triggers, and localization of binding updates.
