  • lkhw a Directed Diffusion based secure multicast scheme for wireless sensor networks
    International Conference on Parallel Processing, 2003
    Co-Authors: R Di Pietro, Luigi V Mancini, Yee Wei Law, Sandro Etalle, Paul J M Havinga
    Abstract:

    In this paper, we present a mechanism for securing group communications in Wireless Sensor Networks (WSN). First, we derive an extension of logical key hierarchy (LKH). Then we merge the extension with Directed Diffusion. The resulting protocol, LKHW, combines the advantages of both LKH and Directed Diffusion: robustness in routing, and security from the tried and tested concepts of secure multicast. In particular, LKHW enforces both backward and forward secrecy, while incurring an energy cost that scales roughly logarithmically with the group size. This is the first security protocol that leverages Directed Diffusion, and we show how Directed Diffusion can be extended to incorporate security in an efficient manner.

  • rtdd a real time communication protocol for Directed Diffusion
    Wireless Communications and Networking Conference, 2008
    Co-Authors: Kenan Casey, R Neelisetti, Alvin Lim
    Abstract:

    In this paper, we propose Real-Time Directed Diffusion (RTDD), a real-time communication protocol for Directed Diffusion. Using the mechanisms provided by Directed Diffusion, we implement a prioritized scheduling policy over Diffusion. With just a few extensions, RTDD significantly enhances the Directed Diffusion protocol, allowing time-critical flows to delivery more packets on time. We also propose two new scheduling policies which do not require location knowledge. We simulate RTDD in ns-2 and compare its performance to standard Directed Diffusion. Results show that RTDD delivers significantly more packets on time than Directed Diffusion alone.

  • Scalable, self-healing, and real-time network services for Directed Diffusion
    2008
    Co-Authors: Alvin Lim, Kenan Casey
    Abstract:

    Directed Diffusion is a data-centric publish-subscribe routing protocol for sensor networks. We have proposed three network services which increase the capabilities of Directed Diffusion. Our protocols build on the inherent strengths of Diffusion and lessen its weaknesses. The system architecture emphasizes efficient communication, local route repair, and real-time response. Our suite of network services significantly improves the performance of Directed Diffusion by addressing the fundamental challenges of sensor networks: energy-efficiency, dynamic environments, and scalability. Our design increases the efficiency of flooding, improves packet delivery rates in the presence of node failure, and decreases the number of packets that miss their deadlines. We evaluate the performance of our improved Diffusion in terms of routing overhead, delivery effectiveness, and deadline achievement. Our results demonstrate the benefits of the network services in all three respects. We increase the efficiency of flooding by 48%, improve packet delivery rates in the presence of node failure by up to 28%, and decrease the number of packets that miss their deadlines by 30-60%.

  • ESAS - SDD: secure Directed Diffusion protocol for sensor networks
    Security in Ad-hoc and Sensor Networks, 2005
    Co-Authors: Xiaoyun Wang, Lizhen Yang, Kefei Chen
    Abstract:

    A sensor network is a collection of tiny sensor nodes, which consists of sensing, data processing and communicating components. Directed Diffusion is an important data-centric routing protocol of sensor networks. In this paper we present the design of a new secure Directed Diffusion protocol (SDD), which provides a secure extension for the Directed Diffusion protocol. We mainly focus on secure routing and give a simple scheme to securely diffuse data. We have not considered with the in-network aggregation as a goal. In order to support the use of SDD for sensor nodes with extremely limited CPU processing capability, we use an efficient one-way chain and do not use asymmetric cryptographic operations in this protocol. Our security analyses show that SDD is robust against any active attackers or compromised nodes in the network.

  • Trust-based secure Directed Diffusion routing protocol in WSN
    Journal of Ambient Intelligence and Humanized Computing, 2020
    Co-Authors: Hua Wang, Huiyu Zhou
    Abstract:

    Deployed in the monitoring environment, Wireless Sensor Network (WSN) is a measurement and control network composed of miniature and low-cost sensors with sensing, computing, and communication capabilities. The design of the Directed Diffusion (DD) routing protocol is one of the key problems in WSN. In order to obtain the confidentiality of sensing data and solve the unreliability of relay nodes in the existing DD routing protocols, this paper designs an Energy Trust Model (ETM) by introducing the remaining energy and trust of a node. We further propose a Trust-based Secure Directed Diffusion Routing protocol (TSDDR) based on the model. The proposed protocol achieves the establishment of a credible communication path and the transmission of confidential data in WSN. Meanwhile, the balance of energy consumption and the privacy of sensing data can be ensured. The performance analysis results show that the TSDDR protocol can effectively defeat against MITM attacks and prevent the malicious nodes’ impersonation. At the same time, the protocol achieves secure end-to-end anonymous communication with acceptable energy overhead and computational complexity.
