Software
Software components for the BikeNet network are organized versus isolated hardware
tiers. Here, we will mention software layers of the appropriate hardware components.
Motes' applications insure intra- and inter-BAN management, data exchange
services, and support for BikeNet roles' completion.
SAPs' applications enable two-side communication, node-based through data
exchange services and server-based through query management. These applications
also include ground truth sensing module, which acts like sensor data filter. This assumes
that even SAPs have some sensors attached, in order to provide high data fidelity.
Applications, running on servers, gather a couple of modules which enable server-
SAP communication, sensor data visualization, sensor data storing (over repositories
and databases), and sensor data mining. Module which is referenced as query submis-
sion portal enables graphical presentation of cyclists' data on the web.
Contribution
Contributions of the BikeNet system include cyclist performance and fitness manage-
ment by collecting data about cyclist's current and average speed, distance travelled,
calories burned, along with time and location metadata; environment and experience
mapping by emphasizing the healthiness levels in terms of pollution, allergens, noise,
and terrain's roughness; long-term performance trend analysis which enables the
upload of data traces into personal repository and selective data sharing; data collec-
tion and local presentation customized by cyclists; data query and remote presentation
on the web-based portal; disconnected operations which refer to opportunistic net-
working paradigm, or the fact that data uploading happens according to the opportu-
nities that arise as a result of cyclists' uncontrolled mobility.

WSN EXMAs - A Conclusion
To conclude, we can emphasize the expansion of WSNs for the past few years. This
certainly is a rising technology. As stated before, a great advantage of sensor nets is
their compatibility to existing infrastructures. Another advantage lies in the fact that
these networks meet a number of completely different applications, agricultural,
ecologic, and especially medical. Miniaturization of sensor nodes and overcoming
of demonstrated issues will bring more sophisticated solutions and applications.

WSN EXMAs - Failure vs. Success
With all new technologies we face with problem of failure or success. Despite
the promising features, risks of failure are always present. In order to overcome
