NeTS-NOSS: Secure, Robust and DoS-Resilient Code Dissemination in Wireless Sensor Networks

无线传感器网络在重要基础设施的监测、危险环境中的数据采集以及军事行动等方面有着广泛的应用前景。 传感器节点通过无线链路部署后通常需要重新编程.该项目的目的是调查安全，鲁棒性和DOS弹性的远程编程的传感器节点通过无线链路。 首先，本研究提出一种整合主动传输与NACK机制的可靠性机制，以有效地容忍编码散布过程中的封包遗失;其次，本研究整合有效的认证机制，以确保散布的编码影像的完整性。 第三，该项目开发了弱认证机制，以减轻潜在的拒绝服务攻击，旨在消耗传感器节点的资源（特别是电池电量）。第四，该项目扩展了上述技术，以在混合传感器网络中提供安全、主动鲁棒和DOS弹性的代码分发，其中既有高端节点（例如，PDA、Intel mote 2）通过高容量无线链路（例如，802.11）和低端节点（例如，MicaZ微粒）经由低功率无线链路（例如，802.15.4）。 为了实现这些技术的透彻理解，该项目实现了所有提出的技术，并评估themin混合无线传感器网络测试床命名为WiSeNeT在北卡罗来纳州州立大学。

Wireless sensor networks are ideal candidates for a wide range ofapplications, such as monitoring of critical infrastructures, dataacquisition in hazardous environments, and military operations. It isusually necessary to reprogram sensor nodes after they are deployedthrough wireless links. This project is aimed at investigating secure,robust, and DoS-resilient remote programming of sensor nodes throughwireless links. First, this project develops a novel reliabilitymechanism that integrates proactive transmission and NACK mechanismsto tolerate packet losses during code dissemination efficiently.Second, this research integrates efficient authentication mechanismsinto this approach to guarantee the integrity of disseminated codeimages. Third, this project develops weak authentication mechanismsto mitigate the potential DoS attacks aimed at consuming the resources(particularly the battery power) of sensor nodes. Fourth, this projectextends the above techniques to provide secure, proactively robust,and DoS-resilient code dissemination in hybrid sensor networks, wherethere are both high-end nodes (e.g., PDAs, Intel mote 2) connectedthrough high-capacity wireless links (e.g., 802.11) and low-end nodes(e.g., MicaZ motes) connected via low-power wireless links (e.g.,802.15.4). To achieve a thorough understanding of these techniques,this project implements all the proposed techniques and evaluates themin a hybrid wireless sensor network test-bed named WiSeNeT at NorthCarolina State University.
