Contextual optimization of location-based routing protocols for multi-hop cellular networks using mobile relays

Abstract

Traditional single-hop cellular architectures fail to provide high and homogeneous quality of service levels throughout a cell area due to the strong signal attenuation with the distance. In this context, multi-hop cellular net- works that utilize mobile relays and device-to-device com- munications have been proposed to overcome the physical limitations of conventional celular architectures. One of the key building blocks of multi-hop cellular networks is the multi-hop routing of information from the source to the des- tination. This paper investigates the performance and energy signaling benefits of location-based multi-hop routing proto- cols. In particular, the paper demonstrates the benefits of a contextual optimization of this type of protocols in order to achieve a high end-to-end performance, while reducing the energy and signaling implementation cost.
