Simplified Distributed Ledger for Task Offloading In Edge Networks

Abstract

Large quantities of processing resources with strict latency specifications are needed for Internet ofThings (IoT) devices due to the rise of compute-intensive and delay-sensitive mobile apps. One promising solutionis to transfer resource-intensive computational tasks from IoT devices to either edge computing servers or cloud computing servers. This paper aims to apply a simplified distributed ledger to an edge network to follow up the offloaded data and maintain the response time as much as possible. The voting process is used as a consensus to validate the new block, while the offloading decision is based on a fixed processing time offloading threshold value. The proposed model has been programmed and the experimental evaluation of the proposed model shows that the ledger did not significantly lengthen the response time and the offloaded task has been successfully tracked
