Modeling Computer Networks for Emulation

Secure Collaborative Spectrum Sensing in the Presence of Primary User Emulation Attack in Cognitive Radio Networks

Collaborative Spectrum Sensing (CSS) is an effective approach to improve the detection performance in Cognitive Radio (CR) networks. Inherent characteristics of the CR have imposed some additional security threats to the networks. One of the common threats is Primary User Emulation Attack (PUEA). In PUEA, some malicious users try to imitate primary signal characteristics and defraud the CR user...

An efficient method for performance analysis of high speed networks : modeling and hardware emulation

Extending NCTUns simulator to support mobile networks

NCTUns is a Linux based network simulator/emulator which has a great deal of features such as the possibility to execute real world applications without modifications, and provision to model a wide range of network devices using real TCP/IP network stack. However NCTUns only supports simulation/emulation of mobile hosts instead of mobile networks. Hence, using the conventional NCTUns, it is not...

Modeling Cooperation between Nodes in Wireless Networks by APD Game

Cooperation is the foundation of many protocols in wireless networks. Without cooperation, the performance of a network significantly decreases. Hence, all nodes in traditional networks are required to cooperate with each other. In this paper, instead of traditional networks, a network of rational and autonomous nodes is considered, which means that each node itself can decide whe...
