5. CONCLUSIONS
The field of sensor networks requires various researches that can account for its
different characteristics from other types of networks. At present, much attention is
given to the foundation technique of sensor networks. As a consequence, not much
emphasis is placed on security. However, increasing dependence on networks due to
our pursuit of convenience of life calls for the necessity of privacy protection and
reliable service, which might emphasize the growing importance of security-related
researches.
In order for an effective, convenient and interactive management of medical
information of patients at a hospital, development of technology for a standardized
system of medical information. Moreover, various measures should be taken in terms
of technology, legalization and ethics to protect and secure medical information and
privacy. These will help us provide safe delivery of medical service and also minimize
repulsion or resistance on the part of patients. In particular, external threat on the
security of any network system has been increasing. It may cause serious harm to a
sensor network, which will be extremely difficult to operate unless enough research on
its security as well as foundation technology is conducted at the very beginning of
developing a system. It may also mean that there is a vast room for improvement in the
field of the security of sensor networks.
