The 11th International Symposium on Wireless Personal Multimedia Communications (WPMC’08) WIRELESS PEER-TO-PEER COOPERATION: WHEN IS IT WORTH ADOPTING THIS PARADIGM?

Abstract

Cooperation over short-range wireless links among devices downloading remote contents through cellular links is a paradigm quickly gaining ground in the view of answering some of the main issues next-generation wireless applications will rise. Among others, energy consumption, data rate, and transfer time are parameters that may likely benefit from this novel communication concept. Aim of this paper is to con-tribute to a better understanding of which are the wireless hy-brid scenarios where cooperation actually works and which combination of wireless links is more performing with respect to others. Our analysis focuses on different short-range net-works technologies for a peer-to-peer communication among cooperating entities, such as Bluetooth, 802.11g, and ad-hoc 802.11g. Long range (cellular) links we concentrate on are EDGE, UMTS and HSDPA. I
