Design and analysis of a dynamic mobility management scheme for wireless mesh network

Area of Science:

• Computer Science
• Networking
• Wireless Communication

Background:

• Seamless mobility management for mesh clients (MCs) in wireless mesh networks (WMNs) is a significant research challenge.
• Existing schemes like MEMO, M(3), and WMM apply uniform criteria for route updates, neglecting individual MC characteristics.
• This uniformity leads to inefficiencies in handling diverse internet and intranet traffic patterns.

Purpose of the Study:

• To propose a novel dynamic mobility management scheme for WMNs.
• To reduce the total communication cost by considering individual MC session and mobility characteristics.
• To handle both internet and intranet traffic efficiently.

Main Methods:

• Introduction of a session-to-mobility ratio (SMR) based dynamic mobility management scheme.
• Dynamically determining an optimal threshold SMR value for each MC.
• Numerical analysis to evaluate the performance of the proposed scheme.

Main Results:

• The proposed SMR-based scheme effectively manages mobility for mesh clients.
• It dynamically adjusts route update criteria based on individual MC characteristics.
• Numerical analysis demonstrates significant cost reduction compared to existing methods.

Conclusions:

• The proposed session-to-mobility ratio (SMR) based scheme offers a more efficient approach to mobility management in WMNs.
• It outperforms traditional schemes like MEMO, M(3), and WMM in terms of total communication cost.
• This dynamic approach provides a scalable solution for managing diverse traffic in wireless mesh networks.
