Multi-overlay information management for IoT-oriented P2P network applications

Abstract

In the IoT environment, network applications such as various content/resource sharing, remote sensing, and so on play an important role to realise flexible and efficient communication on the network. If requested content/resource is retrieved from a huge number of various IoT devices, the amount of content/resource management information increases tremendously and most of IoT devices might not have enough computing/networking resource to maintain such management information. Thus, it is indispensable to introduce scalable management scheme and powerful delegate server for the IoT environment. This paper proposes a peer-to-peer information management scheme using multi-overlay network. The peer-to-peer networking is one of the promising ways to achieve scalability of the network applications and the multi-overlay network plays a role to provide a logical network structure adaptive to requested content/resource distribution. The evaluation results of a prototype with content-based and distance-based overlay networks revealed that we can implement IoT-oriented network applications while keeping practical search efficiency as well as saving network resource.
