Final Report Summary - COOPLAB (A federated testbed environment for experimentation on wireless cooperative networks) Cooperative communications constitute a new access scheme that tends to substitute traditional contention schemes for accessing the medium. The idea is to exploit the broadcast nature of wireless networks through retransmission of overheard information towards the destination, aiming at better performance as a result of spatial diversity. Initial research results are very promising, but are solely based on information theoretic models and simulations. These models involve simplifying assumptions and raise concerns as for the efficiency of the scheme in a real environment. In CoopLab we aim at implementing representative cooperative scenarios and studying their performance in real-life wireless testbeds. The experiments should take place in the already existing wireless testbeds of the partners. The main objective of this exchange scheme is to foster long-term research cooperation at an international level and to create new research opportunities (a) in the area of cooperative communications and (b) in the deployment of a federated easy-to-use environment for experimentation in wireless. The institutes participating in CoopLab exhibit a high level of experience in at least one of the two diverse scientific disciplines required to carry out the project successfully, theory of cooperative communications and wireless testbed implementation and management. Their expertise is proven by participation in relevant international research projects and numerous publications.
