• Mesh devices do not require direct line-of-sight to gatekeeper

• Repeaters provide path diversity to communicate around local obstacles

• Elster controlled mesh network: Gatekeeper (GK) sets up the

local network using 902-928 MHz FHSS radio communications

Network is self healing Any electric device can be used

as a repeater A communication path can

have up to 15 repeaters LAN communications can be

encrypted Algorithms emphasize path

reliability to each device both during and after registration

EA_LAN (900 MHz Mesh Network)

Understanding Mesh Networks

10

Point-to-Point (Star) Networks

• Assumes good path – clear

line of site – high towers

• Obstructions require

multiple tower access

Mesh Point-to-Multi-Point Networks

• Assumes obstacles

• Provides multiple paths around

obstructions

• Strengthens communications paths

• Greater placement diversity


• Historic Dynamic Mesh (for Battlefield conditions) Mesh path diversity provides reliable communications

when mobile All points equal with paths formed dynamically Approach is chatty (open to interference) to allow dynamic

paths Since all nodes are equal, any node can be a security risk


11

Gatekeeper

Gatekeeper


• Deterministic Controlled Mesh – Elster Energy Axis Assumes nodes are stationary and a hierarchy can be

defined Best paths are defined or discovered, and used until no

longer best Algorithms emphasize reliability to each meter/device Since hierarchy, security is more easily controlled


12


• Meters are both meters and repeaters GK Meter Registration begins

with closest meters, and works outward

• Runs periodically Continually improves comm

path

• Meters/Devices broadcast, then: Gatekeeper runs scan process

and registers them

• Meters/Devices monitor for no comms, then: Broadcast to find new GK or

new path

• Continual self healing optimization Primary and secondary paths

regularly utilized
