One basic information the networks absolutely need is time, since time can be used to define the order of events, the age of other information and synchronization points in time between different nodes of the network. Therefore time has gotten a lot of attention from the scientific community.
However there is another very basic information, that is location. Location defines the placement of sensor nodes in the environment. This information again provides means to define detection ranges and further enhance the sensor data that is delivered by the network. The location information can also be used for routing in the network. In this case the location enables a user to exactly define an area of interest in a geographical manner. This user provided information enables the network to efficiently deliver the data from the specified area of interest to the user.
Another dissemination mechanism uses knowledge on the content of the data stream. The data streams are tagged with a topic to which users can subscribe and to which nodes can publish. This communication mechanism is known as Publish/Subscribe. The network tries to efficiently deliver the data to all users, who subscribed on the appropriate topic.
The combination of both mechanism is not yet well discussed in the scientific community. Therefore an evaluation of synergy effects may show further optimization options for WSN.
