Opportunistic Access Point Selection for Mobile Edge Computing Networks

In this paper, we investigate a mobile edge computing (MEC) network with two computational access points (CAPs), where the source is equipped multiple antennas and it has some tasks to be accomplished by CAPs through Nakagami-m distributed wireless links. Since MEC involves both communication computation, first define outage probability taking into account joint impact of latency energy consumption. From new definition, then employ receiver antenna selection (RAS) or maximal ratio combining (MRC) at receiver, apply (SC) switch-and-stay (SSC) protocol choose CAP accomplish task from source. For protocols along RAS MRC, further analyze performance deriving easy-to-use analytical expressions for over fading channels, study parameters on performance. Furthermore, provide asymptotic in low regime noise power, which obtain important insights system design. Finally, simulations numerical results are demonstrated verify effectiveness proposed approach. It shown that number transmit Nakagami parameter can help reduce consumption effectively, SSC achieve same as SC proper switching thresholds
