Wireless sensornetworks

  • No fixed infrastructure

  • Sense physical quantities

  • Monitoring and controlling

  • Densely deployed wireless sensors

  • Small and inexpensive

  • Limited memory and power

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.
