“…Relaying data may be facilitated by a NDC in such cases. This paper addresses the following problem: Given a set of geographically distributed sites with peer nodes with (a) their probability of using the system, (b) their inability to listen to incoming connections from other peers and (c) the requirement of a supporting content distribution system, the aim is to ensure optimal locations of NDCs with respect to geographic routing principles [16,18]. The Round Trip Time (RTT) between any two peers must be minimized subject to node capability constraints.…”
A network topology based on Nano Data Centers (NDC) for an interactive collaborative system is discussed in this paper. The system operates over several nodes that differ in endpoint security and network access. Some nodes are prevented from initiating connections directly and require intermediate nodes to accept requests from third parties. The nodes also constitute a supporting content distribution network. In an interactive system, latency is an important factor in overall system performance. In the context of this paper, users are scattered over a large geographic area and connect to the system at their own convenience. Thus it is necessary to find optimal positions for NDC nodes such that relaying leads to minimal increases in response time for all users. In this paper, an extended hierarchical clustering algorithm is used to create a set of NDC locations across a geographic region. It generates a set of relay locations that can be used in P2P communication.

“…Another interesting line of research is the use of relatively stable peer resources to build nano data centers [5], micro clouds, community clouds, or edge clouds [9]. For example, in [5] all the home appliances are controlled and managed centrally by the telecommunication provider.…”

“…For example, in [5] all the home appliances are controlled and managed centrally by the telecommunication provider. In contrast, our vision of edge-centric computing systems is user-centric and the control comes from the edges towards the core, not the other way around.…”
In many aspects of human activity, there has been a continuous struggle between the forces of centralization and decentralization. Computing exhibits the same phenomenon; we have gone from mainframes to PCs and local networks in the past, and over the last decade we have seen a centralization and consolidation of services and applications in data centers and clouds. We position that a new shift is necessary. Technological advances such as powerful dedicated connection boxes deployed in most homes, high capacity mobile end-user devices and powerful wireless networks, along with growing user concerns about trust, privacy, and autonomy requires taking the control of computing applications, data, and services away from some central nodes (the "core") to the other logical extreme (the "edge") of the Internet. We also position that this development can help blurring the boundary between man and machine, and embrace social computing in which humans are part of the computation and decision making loop, resulting in a human-centered system design. We refer to this vision of human-centered edge-device based computing as Edge-centric Computing. We elaborate in this position paper on this vision and present the research challenges associated with its implementation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
