“…The overall costs of maintaining accurate location records are at present only poorly understood. However, recent work indicates that simply for telephone traffic, the excess network signaling load expense would be much larger than that required for classical fixed traffic [5][6][7][8][9][10]. If migrant programs and databases are included, the aggregate signaling load can only be greater.…”

It is difficult to compare various mobility management schemes since as yet there exist no absolute bounds on optimum performance which can be applied to any procedure regardless of assumptions about mobility, network structure, and the like. It would be useful to fill this gap by developing some general theory, which optimally would precisely relate quantities of interest such as minimum average effort/delay in determining unit locations and minimum average location information dissemination rate over the network in fundamental terms. We therefore note that in order to quantitatively evaluate the average cost of any mobility management scheme, timevarying probability distributions on mobile unit location are required. These distributions might be derived from specific motion models, approximated via empirical data [18, 33], or

“…(9) With no loss of generality, assume log 2 so that 0 ≤ H b () ≤ 1. We can then write (10) Fix H(X) -1 = κ > 0. Calculating the mean of this ordered distribution, E[L], we obtain (11) so that…”
