Linux Implementation and Evaluation of a Cooperation Mechanism for Hybrid Wireless Networks

Communication over multiple hops, such as in hybrid wireless networks, can only work if the individual hops cooperate by forwarding packets from other hops. We present the Linux implementation of our previously proposed cooperation and accounting strategy for hybrid wireless networks called CASHnet. We describe our implementation as well as our testbed, where we performed different evaluations regarding introduced delay and packet processing time. We identify the limitations of our scheme in a real-life scenario and discuss possible improvements
