Jennic enhances wireless sensor network management

23 DECEMBER 2008

Jennic, a manufacturer of 32-bit wireless microcontrollers for IEEEE802.15.4 based low-power wireless applications, 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 (radio frequency identification) 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.
