Abstract
Wireless mesh network (WMN) is advocated as the major supporting technology for next generation wireless Internet. To support anywhere-anytime communications for highly mobile users, WMN needs to have mobility management architecture that supports frequent handover. Hierarchical Mobile IPv6 (HMIPv6) is one such architecture that reduces handover signaling, but has inefficient address space utilization, poor key setup procedure, and IPSec-based security. This paper proposes a secure and light-weight architecture for IPv6-based WMN called secure WMN (SWMN) that is built upon HMIPv6. SWMN allocates address space optimally among the clients and uses a secure procedure for user registration and key setup. It has light-weight and secure mobility management mechanism. A simple analysis is also presented to compare SWMN with HMIPv6.
