Reducing the scope of denial of service attacks in QoS routing
نویسندگان
چکیده
Existing routing algorithms treat Quality of Service (QoS) parameters and secure routing as completely separate entities requiring separate algorithms. In this paper we propose secure QoS Distance Vector and secure Bellman-Ford-Moore routing algorithms that meet QoS requirements and satisfy security concerns. Security is achieved by placing filters in the network. The routing algorithms generate routes through these filters to meet the specified QoS requirements. Simulation results indicate that secure QoS Distance Vector algorithm performs the better of the two algorithms. Moreover, the density of filters and the placement strategy of filters affect the length of the route generated. Keywords-secure routing; QoS; Bellman-Ford; Distance Vector

Advanced operations research techniques for multi-constraint QoS routing in internet
Internet Traffic has grown exponentially over last few years due to provision of multiple class services through Internet backbone. With the explosive use of Internet, contemporary Internet routers are susceptible to overloads and their services deteriorate drastically and often cause denial of services. In this paper, an analysis is made how forecasting technique, routing algorithm and Genetic...
متن کاملA Lightweight Intrusion Detection System Based on Specifications to Improve Security in Wireless Sensor Networks
Due to the prevalence of Wireless Sensor Networks (WSNs) in the many mission-critical applications such as military areas, security has been considered as one of the essential parameters in Quality of Service (QoS), and Intrusion Detection System (IDS) is considered as a fundamental requirement for security in these networks. This paper presents a lightweight Intrusion Detection System to prote...

Wireless Sensor Networks (WSNs) arebecoming increasingly popular, and very useful in militaryapplications and environmental monitoring. However,security is a major challenge for WSNs because they areusually setup in unprotected environments. Our goal in thisstudy is to simulate an Intrusion Detection System (IDS)that monitors the WSN and report intrusions accurately andeffectively. We have thus...

Abstract—Today, botnets have become a serious threat to enterprise networks. By creation of network of bots, they launch several attacks, distributed denial of service attacks (DDoS) on networks is a sample of such attacks. Such attacks with the occupation of system resources, have proven to be an effective method of denying network services. Botnets that launch HTTP packet flood attacks agains...
متن کاملImproving Success Ratio in Multi-Constraint Quality of Service Routing
Multi-constraint quality-of-service routing will become increasingly important as the Internet evolves to support real-time services. It is well known however, that optimum multi-constraint QoS routing is computationally complex, and for this reason various heuristics have been proposed for routing in practical situations. Among these methods, those that use a single mixed metric are the mo...
