New TCP Congestion Control Algorithm Based on Bandwidth Measurement for Seamless Vertical Handoffs iertical handoff that improves TCP performance by measuring the rough end-to-end available bandwidth and calculating the slow-start threshold. By ns-2 simulation it is shown that, compared to previous algorithms, the proposed algorithm enhances TCP performance during vertical handoffs.

A Blind Method Towards Performance Improvement of High Performance TCP with Random Lossess both TCP parallelisation and modification to the aggressiveness of studied AIMD algorithms. We show that our proposed method is no more aggressive than the studied TCP variants in the presence of congestion but more effectively utilises bandwidth in the presence of random packet losses.

Enhanced Fast Handover Mechanism Using MIH Services in MIPv6cheme, we can design the cost-effective network by reducing cover-age overlap between adjacent cells. This is due to the decreased handover initiation time in FMIPv6. From simulation results, it is proven that the proposed scheme can provide a higher goodput for UDP and TCP because it has less service disruption during handovers.

Efficient Protection of Mobile Devices by Cross Layer Interaction of Firewall Approachesesults show that the additional overhead for IP layer filtering is less than 10 per cent, if the number of applied rule sets is less than 200. In addition our cross layer approach can reduce the CPU load caused by the application layer gateway by about 10 up to 30 per cent.
