LOGO Abstract  We propose efficient mobility management schemes based on pointer forwarding for wireless mesh networks (WMNs) with the objective to reduce the overall network traffic incurred by mobility management and packet delivery.  The proposed schemes are per-user-based.  We develop analytical models based on stochastic Petri nets to evaluate the performance of the proposed schemes.

LOGO Existing System  The mobile IP can provide continuous Internet access services for the mobile user and does provide a simple and scalable solution to user mobility.  Yet, mobile IP is not a good solution for users with high mobility.  The hierarchical mobile IP (HMIP) protocol was proposed to employ the hierarchy of foreign agents (FAs) and the gateway FAs (GFAs).  To reduce the number of registration operations and to reduce the signaling latency.

LOGO Proposed System  Hence, we propose an analytic model to evaluate the mean signaling delay and the mean bandwidth per call according to the type of MT mobility.  In our analysis, the MHMIP outperforms the DHMIP and MIP strategies in almost all the studied cases.  WMNs have the advantages of low cost, easy deployment, self-organization and self-healing.  A WMN consists of mesh routers and mesh clients.

LOGO Modules MIPDHMIPMHMIP  It is proposed to reduce the location update messages to the HA by registering the new COA to the previous FA and building a hierarchy of FAs.  The user’s packets are intercepted & tunneled along the FAs hierarchy to the MT.  MT registers with its home network from which it gets a permanent address.  If MT moves outside the home network visiting a foreign network, it maintains its home address and obtains a new one from the FA.  In each group, FAs are connected to each other through a GFA.  A set of GFAs are connected to an HA.  When an MT moves through FAs belonging to the same group, the GFA of this group multicasts the received packet (coming from the HA) to the MT.

LOGO Future Enhancement  We suggests to use this technology in the 3G(Third Generation) wireless network to get video conference facilities in the mobile itself.  Definitely this method will occupy the some part of 3G technology.

LOGO Conclusion  We have proposed an analytical model which evaluates the mean handoff delay per call and the mean bandwidth per call of three mobility management approaches: MIP, DHMIP, and MHMIP.  Our analysis gives in almost all cases a lower mean handoff delay per call and a mean bandwidth per call than those offered by the DHMIP and MIP approaches.
