Internet access requirements within the heterogeneous environments are increasing rapidly; especially in mobile environments, also the ubiquitous mobile users and services proliferated in a wide range, such as users in trains, planes and buses. Network Mobility (NEMO) basic support protocol is an extension from Mobile IPv6 (MIPv6) protocol stated by IETF to handle the mobility on a set of mobile nodes. But this NEMO suffers from a number of limitations like the handoff latency and the optimized

... path especially when number of mobile nodes increased; to reduce the over loaded signaling a new mechanism is proposed to solve the drop link problem inside the Correspondent node, due to the limited binding cache size that may be substantially insufficient to bind a new entries. This paper present the new mechanism named as Distributed Alternative Binding Cache mechanism (DABC), to reduce the packet loss in MIPv6 network environments and also reduce the signaling overheads resulted from deleted links. Network simulator NS-2 has been used to evaluate this mechanism and compare it with the original NEMO.
