After Deploymentmulti-hop communicationVisuals anyoneAd Hoc Networks vs. Sensor NetworksLaptops, PDA’s, cars, soldiersAll-to-all routingOften with mobility (MANET’s)Trust/Security an issueNo central coordinatorMaybe high b in addition to widthTiny nodes: 4 MHz, 32 kB, Broadcast/Echo from/to sinkUsually no mobilitybut link failuresOne administrative controlLong lifetime EnergyThere is no strict separation; more variants such as mesh or sensor/actor networks exist

Vehicle TrackingSensor nodes (equipped with magnetometers) are packaged, in addition to dropped from fully autonomous GPS controlled “toy” air planeNodes know dropping order, in addition to use that as long as initial position guessNodes then track vehicles (trucks mostly)Smart Spaces (Car Parking)The good: Guide cars towards empty spotsThe bad: Check which cars do not have any time remainingThe ugly: Meter running out: take picture in addition to send fine[Matthias Grossglauser, EPFL & Nokia Research]Structural Health Monitoring (Bridge)Detect structural defects, measuring temperature, humidity, vibration, etc.Swiss Made [EMPA]

Virtual Fence (CSIRO Australia)Download the fence to the cows. Today stay here, tomorrow go somewhere else.When a cow strays towards the co-ordinates, software running on the collar triggers a stimulus chosen to scare the cow away, a sound followed by an electric shock; this is the “virtual” fence. The software also “herds” the cows when the position of the virtual fence is moved.If you just want to make sure that cows stay together, GPS is not really needed Cows learn in addition to need not to be shocked later Moo!Economic ForecastIndustrial Monitoring (35% – 45%)Monitor in addition to control production chainStorage managementMonitor in addition to control distributionBuilding Monitoring in addition to Control (20 – 30%)Alarms (fire, intrusion etc.)Access controlHome Automation (15 – 25%)Energy management (light, heating, AC etc.)Remote control of appliancesAutomated Meter Reading (10-20%)Water meter, electricity meter, etc.Environmental Monitoring (5%)AgricultureWildlife monitoring[Jean-Pierre Hubaux, EPFL]Related Areas

RFID SystemsFundamental difference between ad hoc/sensor networks in addition to RFID: In RFID there is always the distinction between the passive tags/transponders (tiny/flat), in addition to the reader (bulky/big).There is another as long as m of tag, the so-called active tag, which has its own internal power source that is used to power the integrated circuits in addition to to broadcast the signal to the reader. An active tag is similar to a sensor node.More types are available, e.g. the semi-passive tag, where the battery is not used as long as transmission (but only as long as computing)Wearable Computing / Ubiquitous ComputingTiny embedded “computers”UbiComp: Microsoft’s DollI refer to my colleague Gerhard Troester in addition to his lectures & seminars[Schiele, Troester]Wireless in addition to /or MobileAspects of mobility
