Analysis of Distance-Based Location Management in
Wireless Communication Networks
The performance of dynamic distance-based location management schemes (DBLMS) in wireless
communication networks is analyzed. A Markov chain is developed as a mobility model to describe the
movement of a mobile terminal in 2D cellular structures. The paging area residence time is characterized
for arbitrary cell residence time by using the Markov chain. The expected number of paging area
boundary crossings and the cost of the distance-based location update method are analyzed by using
the classical renewal theory for two different call handling models. For the call plus location update
model, two cases are considered. In the first case, the intercall time has an arbitrary distribution and the
cell residence time has an exponential distribution. In the second case, the intercall time has a hyper-
Erlang distribution and the cell residence time has an arbitrary distribution. For the call without location
update model, both intercall time and cell residence time can have arbitrary distributions. Our analysis
makes it possible to find the optimal distance threshold that minimizes the total cost of location
management in a DBLMS.
