Mobility mechanisms for mobile/wireless all-IP networks [articol]

Abstract

For the next generation technologies, mobility is more than a necessity, it’s a requirement. Actual developed architectures dedicate a special attention to this aspect. Considering that, this paper analyzes the aspect reflecting the network capability, named mobility. We test and verify the mobile nodes availability to roam in different scenarios, for computer networks and cellular networks. All simulations scenarios were implemented using ns-2 network simulator and for the tested architectures we offer the end-to-end delay during the handover process. The results demonstrate how average end-to-end delay contributes to the QoS global evaluation for a wireless scenario.
