“…Moreover, the authors proposed a technique in which sensor nodes can be inactive for long periods to save energy. However, the authors did not consider that off-the-shelf radios have power limitations that cannot always set the desired transmission power level [1]. Moreover, balancing energy consumption is achieved only for a predefined network deployment that is not well suited for all applications.…”

“…However, in an irregular arrangement, it is not always possible to have a neighborhood with exactly 37.5% of active cells; thus, a range between 35% and 40% will be used instead. These rules follow a similar proportion as proposed in (1). Figure 12 shows the average number of active cells vs. the network lifetime in an irregular arrangement corresponding to a 2D square area measuring 100 m×100 m. The cell's radius is set to 15 m. One hundred sensors were randomly deployed.…”

“…These techniques can be classified into four categories: radio optimization, sleep/wake-up schemes, energy harvesting, and energy-efficient routing. For instance, radio optimization schemes vary the radio module's parameters such as transmission power [1], modulation, and coding to avoid battery depletion. Sleep/wake-up schemes, on the other hand, switch between active and inactive periods to optimize power consumption depending on the delay requirements, traffic load, and topology characteristics.…”

Wireless sensor networks (WSNs) have increased in popularity since they play a relevant role in many applications, such as environmental monitoring, fire detection, and health care, to mention a few. These applications periodically collect data that is relayed to a single sink employing a many-to-one communication pattern. This pattern requires energy-efficient routing protocols since sensors closer to the sink node deplete their energy faster than those sensors located further away. As a result, several techniques have been proposed to solve this problem. For instance, some pieces of research split the network into concentric coronas to provide more energy resources in areas with heavier traffic. However, these techniques use either a predefined network deployment that is not well-suited for all sensor applications or do not always guarantee homogeneous energy consumption. This paper proposes a simple energy-aware routing method based on the Game of Life cellular automaton, which provides a homogeneous energy depletion while extending the network lifespan by considering factors such as residual energy, number of active neighbors, and a sleep schedule. To this end, a discrete dynamic model that takes into account different behaviors of WSN through a set of rules combined with a variation of the A-star algorithm is proposed. Simulation results show that the proposed model accurately balances the energy consumption rate while expanding the network lifetime compared to most recent research works. Furthermore, the proposed method can be combined with path-planning algorithms to improve energy consumption in sparse WSNs.INDEX TERMS Energy-efficiency, cellular automata, game of life, energy hole problem, path planning

“…To protect users from the LE attack, Sanaa et al utilized the fake point to confuse the attackers [21]. Arana et al increased the localization error of attackers by controlling the transmission power [22]. Conventional cryptography is a primary method to protect location privacy from eavesdropping.…”

“…The third exception is the LE attack. Fortunately, once AP can avoid the approaching of an eavesdropper, e.g., AP is mobile, the above weaknesses can be eliminated by adopting TOF/TOA ranging and the dynamic transmission power [22]. Note that with TOF/TOA ranging, the user does not need to inform its current transmission power to the AP.…”

Preserving the location privacy of users in Mobile Ad hoc Networks (MANETs) is a significant challenge for location information. Most of the conventional Location Privacy Preservation (LPP) methods protect the privacy of the user while sacrificing the capability of retrieval on the server-side, that is, legitimate devices except the user itself cannot retrieve the location in most cases. On the other hand, applications such as geographic routing and location verification require the retrievability of locations on the access point, the base station, or a trusted server. Besides, with the development of networking technology such as caching technology, it is expected that more and more distributed location-based services will be deployed, which results in the risk of leaking location information in the wireless channel. Therefore, preserving location privacy in wireless channels without losing the retrievability of the real location is essential. In this paper, by focusing on the wireless channel, we propose a novel LPP enabled by distance (ranging result), angle, and the idea of spatial cloaking (DSC-LPP) to preserve location privacy in MANETs. DSC-LPP runs without the trusted third party nor the traditional cryptography tools in the line-of-sight environment, and it is suitable for MANETs such as the Internet of Things, even when the communication and computation capabilities of users are limited. Qualitative evaluation indicates that DSC-LPP can reduce the communication overhead when compared with k-anonymity, and the computation overhead of DSC-LPP is limited when compared with conventional cryptography. Meanwhile, the retrievability of DSC-LPP is higher than that of k-anonymity and differential privacy. Simulation results show that with the proper design of spatial divisions and parameters, other legitimate devices in a MANET can correctly retrieve the location of users with a high probability when adopting DSC-LPP.
