in recent years mobile networks have expanded dramatically, compared with other wireless networks. routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. in this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...

RFID (Radio Frequency Identification) Systems have gained popularity in recent times and have found large-scale deployment in commercial and enterprise domains. However, there is a dearth of publicly available robust simulation platforms for RFID networks. The ns-2 simulation environment is a flexible tool for network engineers to investigate how various protocols perform with different configu...

The new IEEE 802.21 standard specifies link layer intelligence and other related network information to upper layers in order to optimize handovers between networks of different types, such as WiMAX, Wi-Fi, and 3GPP. This paper makes a short description of 802.21 standard, how it is implemented in ns-2, and the signaling used in a handover between WiMAX and Wi-Fi. The paper also proposes a nove...

Simulation is a powerful tool for analysis and improvement of networking technologies, and many simulation packages are available. One that is growing in popularity is NS-3, the successor to the popular NS-2. It is a significant departure from NS-2, and offers many advantages and disadvantages. In this thesis, we translate and update a sophisticated WiMAX simulation model from NS-2 to NS-3, and...

Multi-technology, multi-homed, multi-hop, multi-interface, multi-channel, multi-route, multi-destination... Emerging wireless networks are multi-* networks. Emerging wireless networks are also no longer stand-alone and self-contained networks but connected to external networks. Simulating such complex systems requires advanced network simulation tools. The network simulator 2 (ns-2) is one of t...
