What can we learn from this development for sensor
networks?
So, the first large-scale Internet was created (1969 to 1982)— a set of
interconnected US military computers (e.g. for e-mail exchange).
Why did it take more than 25 years to revolutionize the world and
And what factors made the revolution finally happen?
The first applications stem from defense research projects with
government. Outside defense, the industrial applications are slowly
moving forward. Why slowly?

Revolution barriers of sensor networks
 Lack of tools and testbets for application development
 Lack of standards at software and hardware level: industry is reluctant to
invest or to do development
a) for non standardized languages, tools, applications and
operating systems.
b) in non standardized languages other than their own one
c) Lack of basic service standards (security, location, name service)
 Sometimes nonproprietary nature: The risks for a software company is that
nonproprietary products are in the public domain and anyone can produce or
distribute them. This also means: there is no one to blame for if hardware level
alterations need to be performed
 Lack of hardware for reasonable prices & reasonable quality: Wireless
nodes and sensors are still pricey, leaving the early implementation to those who
can afford the initial outlay.
 SAP AG 2004, Title of Presentation / Speaker Name / ‹#›
Revolution barriers of sensor networks
Lack of industrial application. The technology is too new to refer to
industrial success stories. Pioneering spirit required from initial
users/customers. Low return on investment in immediate future due to high
technology introduction costs. Lack of industry partners.
Lack of separation of business logic from device logic and network
logic no proper abstraction layers, too low level programming required
 business application developers are not used to deal with low level
programming
Lack of consumer products as a result of reluctance of industry to adopt
the new technology  reduced demands for sensor devices

Learn Lessons from the Internet History?
With sensor networks, we are in a similar situation like the internet in the
early stages. In order to accelerate the technology maturation, we should
learn from the history of the internet. Key factors for success for both
internet and sensor networks are
 standards,
 tools, and
 affordable hardware

marketable business applications
and adaptions
