“…This approach suggests that if devices in close proximity are capable of processing tasks cooperatively, then local area computation groups could be formed and exploited for computation. Indeed, cooperative computation mechanisms by exploiting device-todevice connections of mobile devices in close proximity are developed in [24] and [25]. A similar approach is considered in [26] with particular focus on load balancing across workers.…”

“…where T r n,i is the time that the computed packet p n,i x is received by the collector from helper n, so it is known by the collector. Br Bx+Br RT T data n is the backward trip time estimated by the collector using (24) and packet sizes. The next step is to characterize T u n , which is the estimate made at the collector about the total (cumulative) time that helper n is underutilized.…”

Cooperative computation is a promising approach for localized data processing at the edge, e.g., for Internet of Things (IoT). Cooperative computation advocates that computationally intensive tasks in a device could be divided into subtasks, and offloaded to other devices or servers in close proximity. However, exploiting the potential of cooperative computation is challenging mainly due to the heterogeneous and time-varying nature of edge devices. Coded computation, which advocates mixing data in sub-tasks by employing erasure codes and offloading these sub-tasks to other devices for computation, is recently gaining interest, thanks to its higher reliability, smaller delay, and lower communication costs. In this paper, we develop a coded cooperative computation framework, which we name Coded Cooperative Computation Protocol (C3P), by taking into account the heterogeneous resources of edge devices. C3P dynamically offloads coded sub-tasks to helpers and is adaptive to timevarying resources. We show that (i) task completion delay of C3P is very close to optimal coded cooperative computation solutions, (ii) the efficiency of C3P in terms of resource utilization is higher than 99%, and (iii) C3P improves task completion delay significantly as compared to baselines via both simulations and in a testbed consisting of real Android-based smartphones.

“…Some of the research that addresses efficient computation offload and distribution to the cloud and how it differs from traditional distributed systems is discussed in this paper. Lomotey and Deters (2014) present an additional survey on MCC and start introducing some of the challenges of ubiquitous cloud computing (UCC), defined as consistency in cloud service access from multiple mobile devices owned by a single user. Computational offloading from mobile nodes to middle-tier servers (i.e., surrogates) is mentioned as one way to overcome energy and latency limitations of offloading to remote clouds.…”
