Energy Balanced Source Location Privacy Scheme Using Multibranch Path in WSNs for IoT

Abstract

Source location privacy, one of the core contents of Wireless Sensor Network (WSN) security, has a significant impact on extensive application of WSNs. In this paper, a novel location privacy protection routing scheme called Energy Balanced Branch Tree (EBBT) is proposed by using multibranch and fake sources. This scheme has three phases. In the first place, the data of the source are randomly sent to a certain intermediate node. Then, a minimum hop routing (MHR) from the intermediate node to the base station is formed. Then, branch paths with fake sources are generated dynamically from some nodes on the MHR path. Finally, a tree-shaped structure from real source nodes and fake source nodes to the base station is achieved. In difference to the previous schemes, the location of the real source in the EBBT scheme does not affect the location and the number of fake sources. During the formation of the tree-shaped multibranch paths, the residual energy of nodes is considered sufficiently, and the control of the direction of each branch path is also involved. The influence of the number and length of branches on the network lifetime and network security is also investigated. Experimental results show that the proposed algorithm has the advantages of long network security period and lifetime, as well as high path diversity. Our simulation further illustrates that the EBBT scheme has favorable privacy of the source location without changing the network lifetime.

Recent advancements in privacy-aware protocols of source location privacy in wireless sensor networks: A survey

“…Their model able to defend the smart adversary also means the adversary who has access to both the global and local view of the network. To address the issue of energy consumption in WSN, authors [52]proposed Energy Balanced Branch Tree (EBBT) in SLP. Their model uses fake sources and works in three phases:…”

A Total Randomized SLP-Preserving Technique with Improved Privacy and Lifetime in WSNs for IoT and the Impact of Radio Range on SLP

“…Researchers have put forth a variety of routing strategies to address the WSN privacy issue with source nodes. In [ 15 , 19 , 22 , 25 , 26 , 27 , 35 , 36 ], fake packet-based SLP techniques were put out. Since we realized that for energy-constrained WSNs, such schemes (fake packet/fake sources-based SLP) would be energy-expensive, we do not focus on them.…”

“…The attacker may employ active attacks such as packet dropping or passive attacks such as eavesdropping on the signals. Several solutions have been proposed in the literature by various researchers to mitigate such attacks [ 6 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. Source location privacy (SLP) protection techniques are the name given to these solutions.…”

Source location privacy preservation in IoT-enabled event-driven WSNs

“…The scheme by authors enhances the diversity and randomness of the route positions across the network in the phantom source nodes (Jia et al , 2017). The selection of the next-hop node takes into account the residual energy of the candidate nodes (Wang et al , 2021). The paper examines privacy-aware protocols in routing protocols, parameters and trade-offs in WSNs under practical scenarios (Gu, 2018).…”
