| description | Mobility is the cornerstone of wireless networks. Supporting mobility
requires some form of tracking to locate mobile terminals within the network. In
the wireline ATM network, the terminal is fixed and the terminal is located by
identifying the terminal and following the routing information provided at each
switch along the path. As terminals become mobile, the path to the mobile becomes
dynamic; the terminal and the path are no longer synonymous. Signalling traffic
incurred in tracking mobile users and delivering enhanced services causes an
additional load in the Wireless ATM (WArM) network. Efficient database and
location management schemes are needed to meet the challenges from high density
and mobility of users, and various service scenarios.
In this thesis the three "natural" Location Management Strategies, i.e.,
Timer-Based, Location Area Based and Movement Based are studied and analysed
for a W ATM network. The model used for depicting user motion and call arrival is
Brownian motion with drift process and Poisson arrival process, respectively. The Timer-Based location management strategy is one in which the user
updates its location periodically after an "optimum" interval of time. This optimum
interval of time is based upon the user's mobility and call arrival characteristics and
is therefore best suited for that particular mobile.
In the Adaptive Location Area Based strategy, the user updates its location
on each LA boundary crossing. The size of the LA changes according to the user' s
mobility characteristics. The objective is to minimise the combined average
signalling cost of both paging and registration for each individual mobile user such
that the overall system-wide signalling cost for location tracking can be minimised. |
