Abstract
AbstractIn this paper, by making slight modifications in protocol stack of wireless access points, the proposed CICADA scheme aims at isolating problems related to wireless section of a transmission control protocol (TCP) connection from its wired portion, using IP spoofing and virtual protocol stack scheme. As the simulation results for an 802.11 based system show, the proposed scheme improves the overall network throughput for both DCF and PCF scenarios, while reducing the mean and variance of end‐to‐end delay for voice and video flows due to smarter bandwidth allocation to elastic and real‐time traffic. In addition, the proposed scheme uses a centralized network address translation (NAT) structure that prevents undesired disconnections during handovers and achieves a smaller handoff delay compared with other schemes. CICADA also improves the privacy of wireless sections by constructing virtual protocol stacks corresponding to mobile stations and using hierarchical two‐level NAT structure in infrastructure networks in order to protect the distribution system against outside attacks.
