A Deployable Routing System for Nanonetworks [[[Liaskosdeployable]]]

Abstract: Nanonetworks comprise numerous wireless nodes, assembled at micro-to-nano scale. The unique manufacturing challenges and cost considerations of these networks make for minimal complexity solutions at all network layers. From a networking aspect, packet retransmissions should be kept minimal, while ensuring communication between any two nanonodes. In addition, assigning unique addresses to nanonodes is not straightforward, since it can entail a prohibitively high number of packet exchanges. Thus, efficient data routing is considered an open issue in nanonetworking. The present paper proposes a routing system which can be dynamically deployed within a nanonetwork. Static, dense topologies with numerous, identical nodes are examined. These attributes are especially important in the context of recently proposed applications of nanonetworks. The proposed scheme incurs a trivial setup overhead and requires integer processing capabilities only. Once deployed, it operates efficiently, inducing lower packet retransmission rates than related schemes. 

In a nutshell

The objective of the new scheme is to be dynamically deployable around a selected point, enforcing a system of non-unique addresses as well.

The novel scheme relies on an earlier observation [[[Liaskos2015promise]]]. According to it, in a full flood of packets, certain nodes achieve better reception statistics than others. This can serve as a classification of the nodes. The best-receiving nodes form patterns which depend on the transmission radius of the nodes. 

The scheme combines classification results produced by smaller and larger radii (left inset below) to deploy a system of rings and sectors (right inset below). Packets can then be routed over the combined system, driven by their distance in hops from the beacon "O" at the center. 

 

Key-points

  • This study introduced a deployable routing system (DEROUS) for ad hoc nanonetworks.
  • DEROUS dynamically forms a quasi-radial coordinate system around a given beacon point.
  • Emphasis is placed on low complexity and memory requirements.
  • Each node is assumed to have integer processing capabilites only.
