Policy Based Fast Handoff Mechanism for MANET

Mobile ad hoc Network (MANET) has a challenging task because of the dynamic and infrastructure less nature of the network. This dynamic nature leads to the difficulty in handoff, addressing, routing and data delivering process. For getting good QoS, better flexibility, effective and efficient handoff process in this dynamic network need better handoff mechanism for avoiding any discontinuity, packet loss, delay and jitter during handoff process. Therefore, it is necessary to make fast handoff based on group mobility and policy driven approach for this network. Thus, In this paper, We propose a policy based handoff mechanism with group mobility over hierarchical cluster based architecture involving proactive and reactive handoff approaches based on policy for nodes of MANET.
