This metric depends on the distribution of SINR (Signal to Noise plus Inerference Ratio) values of the given cell. The main task, that the mobile phones can receive the signal stronger than the overall interferences in any point. Consequently the SINR values of DPs have to be increase by an efficiency planning algorithm. The cost of infrastructure is the other key factor. If we used any amount of BSs within our network, then we could serve our demands assuredly lavish in spending. Possibility of increasing of efficiency: – Observing of signal propagation.

Section 4 presents the simulation details and the numerical results that have been obtained. Finally, the paper ends with some conclusions drawn in Section 5. 2 Mobile WiMAX HHO and Related Research Work Although the Mobile WiMAX standard supports three types of HO procedures, namely, the HHO, the Macro Diversity HO (MDHO) and the Fast Base Station Switching (FBSS), the HHO is the default and the most commonly used procedure. The two main phases in the Mobile WiMAX HHO procedure [1] are the Network Topology Acquisition Phase (NTAP) and the Actual Handover Phase (AHOP).

Hence those NBSs that either do not meet the QoS-BW requirement or do not show at least a progressive or approaching relative velocity with respect to the MS are not even considered for (further) scanning. Because of greatly reduced scanning and ranging activities in this scheme, as compared to that in the Mobile WiMAX standard or many of the proposed HO schemes, the overall HO delay here is considerably reduced, thus improving the expected call drop performance. The rest of this paper is organised as follows.
