Abstract: Wireless mesh networks (WMNs) are nowadays considered and

already used as a communication platform for many different applications in

the field of telemetry and automation. Brief introduction will disclose

background, basic principles, algorithms and challenges related to general

WMNs. Further IQRF, an open technological platform for wireless mesh

networks, its basic principles and related routing algorithms will be

presented. IQMESH protocol will be disclosed at TSP conference and IQRF

ecosystem will be first time introduced there as an open technological

platform. IQRF provides complete tools to WMNs deployment, reliable and

effective packet delivery with minimal demands on system resources. Instead

of usage of routing tables, consuming a lot of system resources, it profits from

oriented synchronized flooding based on IQMESH protocol. IQMESH network

formation, nodes discovery, healing, robustness, latency, protocol

specifications and many other technical topics will be disclosed in the

presentation in conjunction with real applications deployment.

Why we need WMN?

WMN is efficient solution for communication needs

WMN increases robustness and reliability

WMN is a must!

WMN respects physics and real environment

Why everybody does not use it?

WMN as a challenge

Each path can be 1 – N hops long

We are working with slow bit rates

Conditions can change in time

Links may not be symmetrical

There are limited HW resources

Routing should be realized in real time

WMN as a challenge: routing efficiency

Optimizing effort may lead to unefficiency

( 8 transmissions instead of 4 )

Network devices are completely controlled by DPA commands,

specifying where and what should be performed:

D.Hayes introduced command set enabling LOCAL control
