4. 3. A Device Message Bus for SensorNetworks

   University essay from

   Author : Dimitri Mazmanov; [2010]
   Keywords : ;

   Abstract : Sensor Networks are typically comprised of heterogeneous technologies as they cover a number of dierent elds, for example, home automation, intelligent transport systems, environmental monitoring and consumer electronics. In order for a systems provider to effciently communicate with such devices, it is necessary to create a layer of abstraction, called a Device Message Bus (DMB), which allows the heterogeneity of the devices to be hidden from the provider.
