“…If the sensors are simply dropped in the field, they will group together to automatically construct an extremely flexible, low power network [7], creating an ad-hoc mesh network by initializing connection with every other node in range, and eliminates the necessity for expensive and cumbersome wiring among nodes [11]. However, the use of cameras has increased the amount of data that has to be transmitted in the network significantly, bringing with it greater challenges, such as the limitation of processing power and memory [12]. The VSNs are usually different from the standard WSN in terms of data operation, as in VSN the data is in the form of pixel values (image) whereas, standard WSN operates with scalar data (numeric).…”

Since the invention of low cost camera, it has been widely incorporated into the sensor node in Wireless Sensor Network (WSN) to form the Visual Sensor Network (VSN). However, the use of camera is bringing with it a set of new challenges, because all the sensor nodes are powered by batteries. Hence, energy consumption is one of the most critical issues that have to be taken into consideration. In addition to this, the use of batteries has also limited the resources (memory, processor) that can be incorporated into the sensor node. The life time of a VSN decreases quickly as the image is transferred to the destination. One of the solutions to the aforementioned problem is to reduce the data to be transferred in the network by using image compression. In this paper, a comprehensive survey and analysis of distributed coding algorithms that can be used to encode images in VSN is provided. This also includes an overview of these algorithms, together with their advantages and deficiencies when implemented in VSN. These algorithms are then compared at the end to determine the algorithm that is more suitable for VSN.

Wireless sensor networks have often been used to monitor environmental conditions, such as temperature, sound, and pressure. Because the sensors are expected to work on batteries for a long time without charging their batteries, the major challenge in the design of wireless sensor networks is to enhance the network lifetime. Recently, many researchers have studied the problem of constructing virtual backbones, which are backbones used for different time periods, to prolong the network lifetime. In this paper, we study the problem of constructing virtual backbones in dual-radio wireless sensor networks to maximize the network lifetime, called the Maximum Lifetime Backbone Scheduling for Dual-Radio Wireless Sensor Network problem, where each sensor is equipped with two radio interfaces. The problem is shown to be NP-complete here. In addition, rather than proposing a centralized algorithm, a distributed algorithm, called a Dominating-Set-Based Algorithm (DSBA), is proposed for a wide range of wireless sensor networks to find a backbone when a new one is required. Simulation results show that the proposed algorithm outperforms some existing algorithms.

“…Sensor networks are widely used in various applications starting from military to environmental and medical research in recent years [1][2][3][4][5][6][7][8][9]. In many WSN applications including target tracking, battlefield surveillance, and intruder detection, WSNs often operate in unattended environment.…”

SUMMARYUser authentication is a prominent security requirement in wireless sensor networks (WSNs) for accessing the real-time data from the sensors directly by a legitimate user (external party). Several user authentication schemes are proposed in the literature. However, most of them are either vulnerable to different known attacks or they are inefficient. Recently, Althobaiti et al. presented a biometric-based user authentication scheme for WSNs. Although their scheme is efficient in computation, in this paper, we first show that their scheme has several security pitfalls such as (i) it is not resilient against node capture attack; (ii) it is insecure against impersonation attack; and (iii) it is insecure against man-in-the-middle attack. We then aim to propose a novel biometric-based user authentication scheme suitable for WSNs in order to withstand the security pitfalls found in Althobaiti et al. scheme. We show through the rigorous security analysis that our scheme is secure and satisfies the desirable security requirements. Furthermore, the simulation results for the formal security verification using the most widely used and accepted Automated Validation of Internet Security Protocols and Applications tool indicate that our scheme is secure. Our scheme is also efficient compared with existing related schemes.
