A Practical Approach to Provide Security in IEEE 802.15.4 Wireless Sensor Network

Abstract

During last years, IEEE 802.15.4 has been asserting itself as one of the most promising standards for Wireless Sensor Network. It includes a security sublayer, which provides a number of operations and procedures aimed at securing network communications. But providing security features and power consumption together face a trade-off. In spite of so many research works discussing IEEE 802.15.4 security service, so far not so many focus on their implementation and performance. This paper discusses some security aspects of IEEE 802.15.4, and presents a practical approach to secure point to point link between wireless sensor nodes in details, supporting all the security suites of the standard. The results demonstrated that our approach achieved significantly lower power consumption and higher performance in security.
