Wireless Sensor Networks have been deployed for environmental monitoring, home automation, and advanced metering application fields among others. Only few examples of monitoring cargo transports by Wireless Sensor Networks have been reported on. The authors have deployed mobile Wireless Sensor Networks in a cargo container on a trans-atlantic cargo vessel as well as on a lorry to monitor the transport conditions inside the container. This submission reports on the experiences gained from those particular deployments and the open research issues for mobile Wireless Sensor Networks for logistics.
