Abstract
Wireless networks with movable base stations
combine the advantages of mobile ad hoc networks and
wireless LAN to achieve both flexibility and scalability. We
present the hierarchical mobile wireless network (HMWN)
to support movable base stations. HMWN may be applied
to ad hoc networks as well to build a virtual hierarchy. In
such a system, mobile hosts are organized into hierarchical
groups. Four basic operations for setting up and maintaining
the network structure are grouping, registration, leaving,
and migration. An efficient group membership management
protocol is developed to support mobile hosts roaming among
different groups. The segmented membership-based group
routing (SMGR) protocol is proposed to take advantage
of the hierarchical structure and membership information.
In this protocol, only local message exchanging is required
for maintaining network topology and routing information.
Simulation-based experiment demonstrates the scalability of
the design in terms of protocol overheads.
