How the Internet came about?
I I I I I
1960Foundation of the Internet,Sending/compression of data packages
Used NCP as transmission protocol1982 replaced by TCP/IP;First large-scale Internet was created as a set of interconnected US-Military computers,Services: email etc.
1979/1980USENET
1968/69 ARPANET
Spirit of freedom of speech, information sharing, introduction of PCs
1991WWW
standard linked information system accessible across the range of different computers in use.
1993the first proper web-browser, Mosaic
341,634% annual growth rate! Important sites like the White House and Pizza Hut appeared. Online shopping sites showed up.
1982TCP/IP

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?
SAP AG 2004, Title of Presentation / Speaker Name / 8
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 / 9
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
