N3: Addressing and Routing in 3D Nanonetworks [[[Tsioliaridou1n3]]]

Abstract: Wireless communication at nanoscale faces unique challenges stemming from low hardware capabilities, limited power supply and unreliable channel conditions. The present paper proposes a networking scheme that can operate efficiently under such physical restrictions. Studying 3D multi-hop networks, the novel scheme offers scalable, trilateration-based node addressing and low-complexity packet routing mechanisms. Analysis is employed to design a routing process that balances path multiplicity for robust data delivery, and minimization of redundant transmissions. Extensive simulations yield increased resilience to challenging network conditions. 

In a nutshell

The present paper introduced the N3, an addressing and routing scheme for 3D nanonetworks. N3 addresses each node (gray spheres below) by its distances from a selected set of anchor points:

These distances also define node-bounding volumes, within which packets are routed via multi-hop retransmissions, from a sender P1 to a receiver P2:

 

Key-points

  • Via the volume approach, N3 naturally provides path multiplicity and node failover, which are mandatory in the challenging nano-environment.
  • A triplet of anchors is selected by a sender-node prior to its transmission.
  • Each triplet selection yields a different boudning volume, allowing for optimization of selection.
  • N3 was optimized analytically in terms of minimization of retransmissions, whilst ensuring the high resilience of the network demanded by many applications, e.g. smart materials.
