ZigBee networks provide the most modern technology infrastructure for wireless devices and other electronic instruments with extra benefits of cost-effectiveness and low-power usage. ZigBee networks are widely used in huge industrial plants to formulate one monitoring and controlling unit. ZigBee networks are spreading rapidly in home environment by replacing the manual controlling of a device with one remote control.
How ZigBee Network works
ZigBee networks uses Coordinator, router (optional) and End Devices to communicate. ZigBee technology based network devices like coordinators, routers and end devices are used to form a ZigBee wireless network. In a ZigBee networking coordinators work as a primary device. It is a source to commence a networking process. Coordinator sends information to the router. These routers are secondary medium which acts as a bridge between coordinator and end device. An important point to remember is end device only works as a receiver within crucial time span less than 15msec.
ZigBee Network Topologies
ZigBee networks also follow different topologies like peer-to-peer and star topologies. First topology known as peer-to-peer topology is networked directly to each other through ZigBee network nodes. One node of ZigBee network device has the option of connecting multiple items hence the ability to form a network.
In peer-to-peer networking topology one node of ZigBee network device is connected with the other node for network formation and form a grid like structure. ZigBee networks offer short range wireless networking with a remote. For further clarification we can say that ZigBee networks relatively form a simpler network without any complexity.
In star topology of ZigBee network, all the devices have one central control unit and devices are attached through coordination with the help of multiple routers to increase ZigBee network range. It is a complex module and is difficult to tell which node is connection to which node but still in case of any breakdown the ZigBee network itself does not get affected and find an alternate route to perform the command sending through coordinator.
Cluster tree topology in ZigBee network is like mesh topology in essence. These clusters are like fruits attached to a central trunk and are ready to be eaten. These clusters are many stars with routers ultimately connect with the coordinator to form a ZigBee network. As per its structure this is the most used ZigBee networking plan in industrial units. ZigBee network never stops its function even if one device or even a one star is not in working condition. By using ZigBee network features of instant connectivity with the immediate available node it continues its function.
A wireless device with low-power deployment has a less danger and easy maintenance. It is like an automatic network to work through a single control system. While not in use the device instantly goes to sleep mode and this feature helps to increase the lifespan of battery. As compared to Bluetooth device it does not need recharge after every use. That’s why ZigBee technology is the most compatible technology presently restricted to industrial zone by using ZigBee networking but near future is of home centralization for security purposes based on ZigBee networking.
ZigBee Network Features
