A Novel Traffic Dividing and Scheduling Mechanism for Enhancing Security and Performance in the Tor Network

Abstract

Objective: The main intent of this research is to improve the quality-of-service in the Tor anonymous communication network by splitting the traffic and scheduling it according to the traffic load. Methods: In this manuscript, a Novel Traffic, Dividing and Scheduling (NTDS) mechanism is introduced for improving performance in the Tor anonymous communication network. The performance of the tor network is described by using various network metrics such as bandwidth, latency, jitter, loss etc. In this mechanism, the traffic load is disseminated across circuits depends on each circuit bandwidth capacity, congestion level, measured latency, throughput. Results: The Novel Traffic, Dividing and Scheduling (NTDS) mechanism show higher performance when compared to the existing router selection method. Throughput, congestion level, latency and available bandwidth are measured for the circuit and based on this the traffic is split and scheduled. If the number of nodes is 50, the packet delivery ratio is 70% in NTDS, the throughput in NTDS is 72% and end-to-end delay is 0.69. According to the comparison results, the proposed approach works better than the other existing systems with high quality-of-service. Conclusion: The findings demonstrate that the Novel Traffic, Dividing and Scheduling (NTDS) mechanism is presented and suggested that this method has high quality-of-service.
