Mobility Management Across Heterogeneous Access Networks

To satisfy customer demand for a high mobility services in heterogeneous network; mobile protocol is needed to make intelligent and optimized handover. This paper is a comparative study between mobility management solutions such as (MIPv6, NEMO, FHMIP and MIPv6 integrated with IEEE802.21) in heterogeneous networks to find out which of them performs better when it comes to send datagram from the correspondent node to the mobile node. Different scenarios were carried out to measure delay and throughput metrics of mobile node while roaming using NS2 (Network Simulator 2). The results showed that mobility protocols integrated with IEEE802.21 performed better in all the tests done and the overall expected handover (both L2 and L3) latency can be reduced even in vehicular environment.
