Abstract

The explosion of heterogeneous devices needs an extended version of edge network. Physical factor, such as time delay and energy cost, is usually used to facilitate resource sensing and neighbor nodes’ networking. In fact, other factors from multiple domains may seriously affect the resource selection and edge network extension. Thus, this paper uses multi-domains fusion connect more nodes from multiple domains and expand edge network. In the proposed edge network model, nodes can thus be selected and combined from a single domain to multi-domains. Moreover, low earth orbit (LEO) satellite can act as a relay node providing excess connection for different domains, and further expands the edge network. To formulate the domains fusion, a two-dimensional matrix is used for each domain. The abscissa and ordinate of the matrix exactly correspond to the tasks and nodes of the offloading process in one domain. Finally, the edge network matrix (selected matrix) can be expanded (increasing of non-zero elements) after the fusion operation. Our analysis and numerical results demonstrate that multi-domains fusion and cooperating with LEO effectively extend the edge network with about 9%.
