Research and Analysis of Open Security Issues in Communication for Wireless Sensor Network

Sensors are resource constrained and computing devices used in wireless networks. These networks are comprised of large numbers sensors deployed randomly over an area. The wireless sensor network (WSN) has a direct impact on human welfare as their application can be extended to military surveillance, environmental monitoring and to healthcare also. Security breaches might lead to grave consequences, so it is important to protect wireless sensor networks against such threats. The specific characteristics of wireless sensor networks make them vulnerable to attacks on their communication channels and their hardware. This research work discusses the open security issues in WSN. Section 2 focuses on the problem statement and later, existing security mechanisms are discussed. This research paper also present an discussion on the Cryptographic mechanisms, which can be employed to protect against some of the possible attacks such as eavesdropping and the injection of messages by the attacker is prevented by authentication.
