摘要：Wireless sensor networks (WSN), sometimes called wireless sensor and actuator networks (WSAN),are spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature,sound, pressure, etc. and to cooperatively pass their data through the network to a main location. WSN are playing agreat role in the controlling and managing environments in different situations and has become important part ofresearch area. WSN research is usually classified into three categories i.e. hardware & software of the sensors nodes,application area, and communication & security. Due to limited resources of computation power, battery,communication range, WSN are vulnerable to different types of attacks and providing security of WSN is really agreat challenge. In this paper we first discuss various security issues concern with the security of WSNs; next wedescribe various security requirements of WSNs and in the en end of the paper we discuss research issues that areconcern with WSNs.One of the major challenges wireless sensor networks face today is security. While the deployment of sensor nodesin an unattended environment makes the networks vulnerable to a variety of potential attacks, the inherent power andmemory limitations of sensor nodes makes conventional security solutions unfeasible. The sensing technologycombined with processing power and wireless communication makes it profitable for being exploited in great quantityin future.
