Wireless Sensor Networks: A Study on Security Goals and Issues

Wireless Sensor Networks (WSN) is a most rising technologies and it is also a challenging research domains in today’s’ era. A wide range of applications used in WSN’s like, education military, health, agriculture, industry/business and environment etc. The WSN technology is highly faced with the issues of network and functional security of natural limits in energy and computing power. The attacks may affect on any hardware or software to damages these networks. These networks produce most recent security threats in contrast to conventional techniques, due to various excellent features of the networks. There are numerous security goals in the networks and these goals must be kept in mind while designing of security solutions for these networks In this study, we have covered a variety of security attacks like Jamming, Hello, Sybil, DoS,, & selective forwarding attack and further, we focused on other security issues of wireless sensor networks and its countermeasures.
