WiseMAC

Peer to Peer low power medium access protocol for wireless communication.

WHAT IS WiseMAC?

WiseMAC is a peer-to-peer MAC protocol for wireless communication that allows ultra-low-power operation with low latency. It is based on an adaptive preamble sampling and does not require any network synchronization. It may be used to construct multi-hop networks with battery-operated routers. In star networks, it outperforms most protocols in terms of downlink latency (sensor parametrization or actuator update) with similar uplink performances.

WiseMAC:

• Asynchronous MAC protocol for wireless networks
• does not require any setup signalling
• is completely asynchronous and does not rely on any network wide synchronization
• outperforms IEEE 802.15.4 (ZigBee/Threads/…) and most low power protocols both in terms of power consumption and latency
• ultra-low-power peer-to-peer communications with low latency
• supports multihop networking with battery operated routers
• optional multichannel operation for safety and dependable operations
• available on COTS devices (incl. 802.15.4 transceivers) and CSEM SoCs.

APPLICATIONS

• Safety (e.g. ship evacuation, avalanche detection)
• Building control & surveillance
• Environment (e.g. water quality monitoring)
• Agriculture (e.g. vineyards)
• Smart homes / home automation
• Asset tracking, people / patients monitoring and more…

What’s new?

• No configuration
• Ultra-low-power peer-to-peer operations (on both peers)
• Smoothly adapts to varying traffic from very low to medium
• Low latency sensor configuration and actuator update in star mode

WHAT’s NEXT

Further energy reduction through adaptation

INTERNATIONAL RECOGNITION:

Numerous publications and references in international journals and conferences.
