“…However, providing SLP for the case of multi-source scenario-the real-life scenarios has been given less attention. To date and to the best of our knowledge, it is found that the only works that have developed SLP preserving solutions for the multi assets scenarios are seen in [13] and [24]. To fill this gap, we aim to study the performance of SLP preservation solutions (both existing and proposed solutions) developed for WNSs when multi-sources co-exist.…”

A major limitation to the use of Wireless Sensor Networks (WSNs) in asset monitoring applications is the security and privacy concerns, particularly the privacy of source location information. In this paper, we develop two phantom routingbased solutions to provide source location privacy for the case of multi-source/asset scenario-the case that has received very little attention in the literature. The idea of phantom routing is to relay the packets to a distant node in a random fashion to obfuscate the traffic flows and confuse the attacker. The first technique PRBRW uses a combination of backward random walk and a greedy forwarding approach to route the packets to the base station (BS). Although the first approach has better performance improvements in terms of capture ratio and safetyperiod it hampers the lifetime of the network and has a poor entropy metric. To better this problem, an improved phantom routing scheme PRLPRW is proposed. The second technique has three phases: pure random walk, L-walk, and greedy walk. This technique performs well in terms of capture-ratio, safety period, and entropy metrics. The improvement in network lifetime is 10-folds and entropy is 477-folds when compared with PRBRW. The performance is evaluated using the developed analytical models and compared with the base-line protection-less scheme SRP. It is observed that PRBRW and PRLPRW respectively have 60-and 73-fold improvement in terms of capture ratio when compared with SPR. Whereas existing PRPRW and FRW techniques respectively have only 54-and 34-fold improvements.

The constant demand to secure the location of an asset in wireless sensor networks (WSNs) has led to the need for the development of location privacy preservation mechanisms. Source location privacy preservation, particularly for a single source has received tantamount attention in the last few years, whereas very few schemes have been discussed for securing the location privacy of multiple sources. To address this issue, in this paper, we have proposed a red‐zone‐based angular routing technique to provide location privacy for multiple sources against local adversaries who continuously eavesdrop and backtrack the packets in the network. The proposed technique termed as red‐zone‐based randomized angular routing (Red‐RAR) establishes a red zone around all the source nodes exists in the network to divert the routing path of a source node away from other source nodes. The Red‐RAR algorithm consists of four different phases that contributes in moving the packets far away from the source and maximizes the path diversity to mislead the adversary. The performance of the proposed algorithm is evaluated through extensive experiments. The experimental results reveal that Red‐RAR outperforms the current state of the art methods in terms of efficiency measured in safety period, capture percentage, and network lifetime for four source nodes.
