Advanced River Formation Dynamics for Location Area Management in GSM

Abstract

To handle call delivery for mobile station, itsprobable location should be known to the network. For that location management is required. Location Management has two basic operations: location update and paging.The goal of an efficient location management scheme is to maintain and provide locations of mobile stations at low cost. This paper presents location area based approach proposed by researchers and nature inspired approach proposed by us, to reduce location management cost.However, there is trade off between reduction of location update cost and paging. Simulation Results of a basic location area scheme and nature inspired technique(river formation dynamics) is presented.

Applications of river formation dynamics

“…In [40,41] authors use RFD to aggregate cell areas into larger location areas, trying to minimize the overall cost of location management. The cost is computed by using the mobility model defined in [42].…”
