Jennic has released the next generation of its cost-effective wireless networking protocol stack, JenNet 1v4. The new release introduces a list of new features for enhanced network management and control, addressing the requirements of applications such as building monitoring and control, industrial control and automation, medical, asset tracking and street lighting.
New features in the release include the ability to perform dynamic load balancing to avoid data bottlenecks within the network and automatic collation and reporting of network statistics such as link quality, packet retries and lost packets to enable improved network management. Automatic network re-shaping has also been added to minimise the number of data path hops between nodes in a network, ensuring compact network configuration and minimal data latency to improve performance in applications such as alarm monitoring systems.
The release supports node mobility, which enables asset tracking and RFID applications, and fast startup capabilities that allow a 250 node network to fully recover in 5 minutes following a complete power outage, minimising network downtime.
The JenNet 1v4 stack typically requires only 52 KBytes for coordinator/router functions and 38 KBytes for end devices in the JN5139 wireless microcontroller, leaving ample code space for most applications.
JenNet is Jennic’s free proprietary wireless networking stack for its range of single chip 32-bit wireless microcontrollers, with a focus on ease of use through a series of simple application programming interfaces called Jenie and AT-Jenie. JenNet offers a robust and field-proven networking solution for applications requiring many hundreds of nodes connected in star, cluster tree or long-thin network configurations. The current version of JenNet runs on all Jennic wireless microcontrollers.
