Why are mesh networks used more frequently for IoT networks?

TL;DR: Economics Wired mesh network vs. star topology Well, the Internet is a mesh network. Why? Because DARPA wanted it to work even if half the United States were bombed into oblivion if the cold ...

A low cost alternative option for ZigBee stack in mesh network of sensors

If you're not married to Zigbee's flavor of 802.15.4, you should take a look at Helium's end-to-end wireless capabilities. (I work for them - naturally.) Our module uses the same PHY but pushes most ...

Are wireless mesh networks limited to PAN applications?

That is a very good question and actually my current research topic. I try to give an adequate but concise answer¹. I will focus my answers to networks based on the IEEE 802.15.4 standard (Zigbee and ...

Why are mesh networks used more frequently for IoT networks?

Mesh networks tend to give better local configuration options for an IoT network. Range extension was already mention which the mesh network as each device in the network will help make the network ...

ZigBee sleep problem

You say you built a Zigbee network using Digimesh protocol. The thing is that this is an impossibility: Zigbee and Digimesh are competing solutions for mesh network, not something you use together. ...

Is wireless mesh a poor choice for sleepy devices?

It is actually possible to allow for sleeping nodes without the need for time synchronization. The basic idea is to send a message multiple times until the node finally wakes up. There is of course a ...

ESP8266 Mesh Network Root Node

Another option to easy mesh is to use painlessMesh by BlackEdder and introduce there a bridge for commuting the data to outer world. There is an issue on connecting to other network from a mesh in ...

ESP8266 Mesh Network Root Node

I would modify a bit the existing implementation of EasyMesh, as currently it does not seem to implement node roles. Each node is equal and they can build connections only with each other. As I see ...

Rearrange Z-Wave network

The rated range of Z-Wave devices in general is designed for indoor "perfect conditions" so if the max range of a device is 100 ft. that assumes no noise and no interference. If you have any other ...

Do protocols based on the publish-subscribe pattern negate the benefits of mesh networks?

Yes and no. Both technologies are concerning different levels of providing connectivity. Usually mesh networking is provided by level 3 or 4 or even both of the ISO OSI model, depending on the extend ...

Why are mesh networks used more frequently for IoT networks?

IoT is often used in home automation contexts (door sensors, wallplugs,...) and they tend to be very far each other especially in big houses. So a mesh network allows objets to cover the distance ...

Sensor using X10 power line protocol connection to Raspberry Pi

I had an Ubuntu system with X10, CM11A, and heyu for several years and switched it all over to a Raspberry Pi about 4 years ago. I then replicated it twice for my parents, and a sibling. It can be a ...

A low cost alternative option for ZigBee stack in mesh network of sensors

I would suggest painless mesh or easy mesh. Their Github pages (on the links) say specifically that they are for esp8266 and thus they are very cost effective.

A low cost alternative option for ZigBee stack in mesh network of sensors

Not sure what your range is, but short range you can use ANT Blaze as well. It's great for continuous data rates. ANT radios I think consume ~20mA at max power. I think module cost is in your price ...

How to tell if a Zigbee device is a Zigbee Router

In general, if it is connected to mains power, it’s a router, whereas if it is battery-powered it’s an end device. Not sure this is 100% true, but probably very close to it. This page shows it is an ...

Are there wireless to wireless routers for meshing, and if not why?

The answer to point one is because it's more efficient and cost. Mesh devices already have at least 2 radios, one to talk to clients and one to talk to other mesh nodes, the master node would then ...
