| Summary: | In Femto-Macro heterogeneous network,
femtocell user equipment (FUE) has main priority in resource
allocation compared to macro users equipment (MUE). MUE
will suffer severe interference when they are placed near or
within the femtocell area range at the cell edge. This condition
occurs due to the distance is far from its serving macro base
station (MBS) to receive good signal strength. Cell selection
scheme is one of the techniques that can improve the network
performance and ensure achievable user data rate. In this
study, cell selection mechanism is proposed to ensure MUEs
also have a priority in resource allocation from the closest femto
base station (FBS) to mitigate interference. The mechanism
includes measuring the closest FBS distance, Signal to
Interference-plus-Noise-Ratio (SINR), physical resource block
(PRB) availability and node density level for base station
selection with the aim of resource block can be allocated fairly
to MUEs based on user demands. Hence, the higher network
throughput can be achieved. |
