A simulation based study of IP mobility over IPv6 networks

IP mobility, one of the current research topics for the researchers. With the emergence of Internet of Things (IoT); the world of interconnected physical objects, IP mobility has taken a great pace. Most of the interconnected things in IoT would be mobile and need efficient mobility management schemes to handle their mobility. There are standardized mobility management protocols; host based (MIPv6 and its extensions) and network based (NEMO and PMIPv6 and it extensions). These protocols are being used to carry the mobility of Mobile Node (MN) with the minimum handover delay and keep the MNs connected to the network all the time to avail the network services. In this paper, we have evaluated the performance of MIPv6 with its extensions and PMIPv6 with its extensions. Through the simulation over Network Simulator (NS2) different performance parameters were calculated by increasing the simulation time to show their performance. We observed from the results, the extension of basic mobility protocols are best to reduce handover delay and to avoid packet loss and also where host based protocols are not suitable, network based mobility protocols provide fruitful results.
