Wong, Department of computer Science, University of Liverpool Wireless sensornetworks • No fixed infrastructure • Sense physical quantities • Monitoring and controlling • Densely deployed wireless sensors • Small and inexpensive • Limited memory and power Management Center (Database large storage, analysis) Different types of wireless sensors Making it all make sense Modelling sensor networks No sensation without representation Broadcasting problem One-to-all: A sensor has a message to be sent to all the other nodes in the network Gossiping problem All-to-all: Every sensor has a message to be sent to all the other nodes in the network Routing Problem One-to-one: A sensor has a message to be sent to another particular sensor in the network.
