In seminal work on SLP, phantom routing was proposed as an approach to addressing the issue. However, results presented in support of phantom routing have not included considerations for practical network configurations, omitting simulations and analyses with larger network sizes. This paper addresses this shortcoming by conducting an in-depth investigation of phantom routing under various network configurations. The results presented demonstrate that previous work in phantom routing does not generalise well to different network configurations. Specifically, under certain configurations, it is shown that the afforded SLP is reduced by a factor of up to 75.

As wireless sensor networks (WSNs) have been applied across a spectrum of application domains, the problem of source location privacy (SLP) has emerged as a significant issue, particularly in security-critical situations. In the seminal work on SLP, phantom routing was proposed as a viable approach to address SLP. However, recent work has shown some limitations of phantom routing such as poor performance with multiple sources. In this paper, we propose phantom walkabouts, a novel version and more general version of phantom routing, which performs phantom routes of variable lengths. Through extensive simulations we show that phantom walkabouts provides high SLP levels with a low message overhead and hence, low energy usage.

“…The main drawback of fake packet injection is that the injected traffic will undoubtedly decrease network throughput and increase power consumption, especially for resource-constrained wireless networks such as wireless sensor networks. ACS (Anonymous Communication Scheme) is proposed in [14], which adopts the keyed hash result of address and sequence number as addresses. As the sequence number is increased on successful transmission, the resulting address changes dynamically and is unknown to adversaries.…”

Due to the broadcast nature of wireless channel, attacks against wireless sensor networks are much easier to carry out as compared to wired networks. Passive attacks such as eavesdropping and traffic analysis cannot be eliminated even if cryptographic technologies are used. Conventional frames are usually designed to include checksum, which facilitates to adversaries capturing correct frames for further attacks. In most wireless sensor networks, source address and destination address at data link layer are unprotected, which makes traffic analysis quite easy. In this paper, we argue that the long-hold design principles of data link layer protocols are unreasonable from the perspective of wireless security. A secure ARQ scheme for wireless sensor networks named Sec-ARQ is proposed. Without the help of preshared keys or complex authentication infrastructure, Sec-ARQ protects frame checksum and addresses by cumulated checksum. Cumulated checksum is unknown to adversaries because of unavoidable wireless transmission errors. As frame checksum is unavailable to adversaries, error frames caused by collision cannot be detected, rendering eavesdropping useless. Addresses protection provided by cumulated checksum disables traffic analysis attacks. Sec-ARQ can defend against passive attacks effectively. Simulation results prove that Sec-ARQ can improve wireless security with little performance sacrifice, which is more suitable for resource-constrained wireless sensor networks.
