Policy based handoff in MIPv6 networks

As the requirements on high-availability for multimedia intensified new applications increase the pressure for the higher bandwidth on wireless networks, just upgrading to the high capacity network is essential. However, that is not especially for solving the handoff-related problems. Policy-based network (PBN) technologies help MIPv6 networks ensure that network users get the QoS, security, and other capabilities they need. PBN has the intelligence, in the form of business policies, needed to manage network operations. In this paper, we propose the Policy Based Handoff (PBH) mechanism in mobile IPv6 (MIPv6) networks to have more flexible management capability on MNs. PBH employs dual routing policy so that it reduces the fault rate of handoff up to about 87% based on the same network parameters and solves the ping-pong problem. Experimental results presented in this paper shows that our proposal has superior performance comparing to other schemes.
