What is Task Migration

Encyclopedia of Information Science and Technology, Fifth Edition
Contemporary mobile devices offload large amounts of computationally intensive tasks to resource-rich cloud servers for processing. Task migration broadens the scope of conventional computation task offloading by not only transferring the task from an MU to cloud servers/surrogates but also from one cloud server/surrogate to another one for execution.

Abstract
To facilitate making the human-machine co-activity-based human-agent-robot teamwork (HART) task execution process more efficient, this chapter first discusses related work and open challenges for latency-sensitive HART task. To speed up the HART task execution, this chapter next presents a latency sensitive HART task migration scheme for efficiently orchestrating tasks among human mobile users (MUs), central and decentralized computational agents (cloud/cloudlets), and robots across converged FiWi network infrastructures. Moreover, this chapter describes a bandwidth allocation scheme that allocates timeslots to MUs' broadband and task migration traffic at the same time. Furthermore, this chapter presents performance evaluation results of the proposed scheme. Importantly, this chapter compares the performance of the proposed task migration scheme with traditional schemes. This chapter is finally concluded by summarizing important findings and outlining open research issues for HART task coordination over FiWi-enhanced tactile internet infrastructures.
