This paper addresses three prime issues of fifth generation mobile network: frequency allocation, power efficiency and communication while computing. This paper proposes a power-efficient micro-femtolet/macro-femtolet network based on soft fractional frequency reuse. Macrocell/microcell base stations are used in the network, and for providing good signal strength and offloading facilities to indoor and edge region users’ femtolets are allocated inside the macrocell/microcell. The power transmission in the proposed heterogeneous network (HetNet) is estimated. The analytical evaluation presents that use of SFFR reduces the power transmission of the network by 10.87% approximately. This is also observed that the signal-to-interference-plus-noise ratio (SINR) of the network is improved using the proposed strategy. For experimental evaluation we have used vector signal generator (VSG) and vector signal analyzer (VSA). The simulation analyses performed using network simulator Qualnet shows that femtolet provides ∼ (2–34)% reduction in energy consumption than the cloud based offloading.
