STWSN: A novel secure distributed transport protocol for wireless sensor networks

Several transport protocols for wireless sensor networks (WSNs) have been designed to fulfill efficiency requirements such as energy and reliability. Unfortunately, most of these transport protocols do not include sufficient security mechanisms and hence are vulnerable to numerous reliability and energy attacks. To address these vulnerabilities, this paper proposes a novel secure transport protocol, named as secure transport protocol for wireless sensor networks (STWSN). On the basis of distributed transport for sensor networks (DTSN) protocol, our protocol adds a new security extension in order to provide secure transport protocol. We provide both informal and formal security analyses of STWSN and show that it resists attacks on energy efficiency and reliability requirements. Last but not least, a performance analysis and simulation results are also presented.
