Overview of Survey on Security of Wireless Sensor Network

Abstract

As a product of the combination of wireless communication technology, intelligent sensor technology and network technology, wireless sensor network has broad development prospects and more and more scholars have been attracted to that study. Moreover, in the military field, national defense field and other special fields, the security research of wireless sensor network has also been put on the agenda. This paper will briefly introduce the basic concept of wireless sensor network first. After that, the existing wireless sensor network security problems will be raised and the research situation of the security of wireless sensor network will be analyzed. The last part of this paper is about the further research tendency for wireless sensor network security. Keywords-Wireless sensor network; security; overview; new development I. INTRODUCTION WSNs(Wireless sensor networks) refer to the wireless ad-hoc networks that are composed of the micro sensor nodes which are arranged within the monitored region. The micro sensor nodes are low in price, small in volume and they have computation and communication abilities. These sensor nodes are usually composed of sensors, data processing units, wire-less communications units and power supply modules. These highly-integrated nodes will be used in the hostile environment after being specially packed so as to detect all kinds of key data that can not be acquired by human beings directly. Thus, the wireless sensor networks can be widely applied in detection of ecological environment, informatization of industrial manufacturing, intelligent safegu-ard systems, aeronautics and astronautic aerospace, battlefield awareness and other fields.
