- Supporting Classes of Service in Bluetooth
- Bluetooth is a wireless ad-hoc network concept primarily intended to eliminate the cables between portable and/or fixed electronic devices. Bluetooth supports both real-time voice and non-real-time data communication services. In this paper, a non-real-time communication service in Bluetooth is considered. Depending on its QoS (Quality-of-Service) requirements, the non-real-time traffic is...

- Subtle Issues in the Design of a Database Tier Firewall
- Applications such as centralized Supply Chain Management permit multiple business partners to host their own customized components at the same site with selective access to a common shared database. If the application software providers are not all trusting of each other, a Database Tier Firewall is necessary. This model assumes...

- An Integrated Framework for Proactive Mitigation, Characterization and Traceback of DDoS Attacks
- Denial of Service DoS attacks pose a severe security threat to the steady functioning of any network. These attacks aim at depleting the resources of a server or an administrative network by overwhelming it with enormous and useless traffic. The outcome of this is the fact that legitimate users are...

- Improving TCP Performance Over Mobile Wireless Environments Using Cross Layer Feedback
- Transmission Control Protocol TCP is known to suffer from performance degradation in mobile wireless environments. This is because such environments are prone to packet losses due to high bit error rates and mobility induced disconnections. TCP interprets packet losses as an indication of congestion and inappropriately invokes congestion control mechanisms,...

- TCP K-SACK: A Simple Protocol to Improve Performance Over Lossy Links
- This paper proposes k-SACK, a TCP variant that has considerably improved throughput characteristics over lossy links. A k-SACK source does not consider every packet loss as an indication of congestion. It uses the Selective Acknowledgement option to estimate a parameter lookaheadloss, which is used in congestion detection. The results demonstrate...

- An Extension of the TCP Flow Control Algorithm for Wireless Networks
- Reliable transport protocols such as the Transmission Control Protocol TCP are tuned to perform well in traditional wireline networks where packet losses occur mostly because of congestion. However, networks with wireless and lossy links also suffer from significant packet losses due to bit errors and handoffs. TCP responds to all...
