A Partial Computation Offloading Strategy for Microcell-femtolet based Future Generation Edge-Cloud Network

Abstract

Fast and low power offloading is an emerging area of interest for future generation mobile network. This paper proposes a partial computation offloading strategy for microcell-femtolet based edge-cloud network. In the microcell-femtolet network microcells contain femtolets inside their coverage area to provide good communication and computation facilities to the user devices at indoor region. An indoor user is connected with the femtolet and an outdoor user is connected with the microcell base station in the microcell-femtolet network scenario. When a computation has to be partially offloaded, the task is partitioned into two segments, one is locally executed and the other one is offloaded to the femtolet or edge server according to the user's presence at indoor or outdoor region. The theoretical and experimental results illustrate that the proposed partial offloading scheme reduces the latency and power consumption of the mobile device than the cloud based approach.
