Forward pointers are employed by R. Jain in mobile communication to reduce the burden ofHLR and network
In this paper
theoretical model is built to analyze the performance of the strategy. Simulation resulil illustrate that the model fits perfectly to the fact . When call-to-mobility ratil(CMR)is high
total network costs increase. So an adaptive method is suggested here. Simulation results show that it adjusts the maximumlength of the forward pointer chain to get minimal cost for different CMR. When CMR is high
it automatically stops using forward pointer strategy
