“…To the best of our knowledge the barrier coverage problem in wireless camera sensor networks was first presented in [13], in which the solution was divided into three phases. The first one consists in collecting the geographical information of neighboring nodes in order to determine the barrier lines.…”

Because of the visual nature (images and videos) of the captured data, the coverage problem in Wireless Multimedia Sensor Networks (WMSNs) is totally different from traditional scalar sensor networks and can be defined in several ways according to the target application. In this paper, we focus on one particular coverage, we called Closed Peripheral Coverage (CPC). This type of coverage is present in several realistic application as military camp surveillance, very sensitive buildings (i.e., nuclear center) surveillance, contaminated region monitoring, etc. The objective hence is to detect any intrusion coming from the outside (viewed by at least one multimedia sensor node). To the best of our knowledge, this is the first research work addressing this issue. Briefly, CPC problem can be defined as follow: after a random deployment of multimedia sensor nodes around the region of interest (i.e., Building to monitor), the goal is to schedule several sets of nodes (i.e., cover sets) such that each of which forms a closed "ring" around the region of interest. Hence, instead activating all nodes at once, the cover sets are scheduled to be activated serially, which ensures a significant network lifetime prolongation improvement. In this paper, we study the CPC problem and present two variants of a centralized algorithm. The preliminary simulation results show clearly the effectiveness of the proposed approaches by a factor varied from 2 to 8 in comparison to the basic approach.

“…But, as camera sensor has different angle that is not omni-directional view, many researchers have considered specific angle. In [15], the author proposes a distributed algorithm to achieve barrier coverage on wireless camera sensor networks. In [16], the author proposes a new method to select camera sensor to make barrier coverage and reduction method to effectively reduce the number of cameras used.…”

Recently, vehicular ad hoc network (VANET) is receiving lots of attentions as this new networking technology is expected to improve our daily driving experience greatly and will enable a number of emerging applications. It is envisioned that the vehicles in VANETs are armed with a number of advanced technologies such as wireless transceiver, video cameras, etc. This paper investigates the potential of the advanced VANET nodes to construct an impromptu surveillance system to surround an area of interest, which can be a city block, such that any suspect of interest leaving the city block can be monitored by a VANET node participating the surveillance system. Such a system can be useful to provide an emergency response system to keep the track of suspects who are leaving the area by walk or by car after committing a crime inside the block, e.g. Boston bombing suspects. We observe that as the network bandwidth is limited, not all vehicles can participate and transmit video to the control center in real time. Therefore, we propose new scheduling algorithms for the VANET nodes, which consider the mobility of each vehicle as well as the network bandwidth and continuously provides barrier-coverage circumventing the city block over a given mission period. Via simulation, we show the efficiency of our algorithms.

“…Shih et al 11 proposed a distributed algorithm, namely CoBRA (Cone-based Barrier coveRage Algorithm), to achieve barrier coverage in wireless camera sensor networks (WCSNs). The basic concept of CoBRA is that each camera sensor can determine the local possible barrier lines according to the geographical relations with their neighbors.…”

Closed-circuit televisions serve as prevention against crime, and many studies for closed-circuit television deployment have been conducted. The closed-circuit television deployment in downtown is similar to solving coverage problem in wireless camera-based sensor networks. The difference between the two problems is various environmental factors such as buildings, roads, camera capability, and movements of pedestrians. We use a genetic algorithm to increase the efficiency of closed-circuit television deployment in two-dimensional topography. In addition, a parallel experiment using general-purpose computing on graphics processing units is added to improve computing speed, which is a disadvantage in genetic algorithms. The target region is 500 m 3 500 m and consists of 50 3 50 grids. The fitness of the evaluation, which refers to a detection rate, is calculated from the corresponding cell when a pedestrian moves to each cell depending on whether the pedestrian is detected. The proposed experiment was superior to the random deployment experiment by approximately 37.5%. There was no significant difference in the detection rate between the CPU experiment and a NVIDIA GeForce GTX 970 experiment in the 95% confidence interval. The efficiency of a CUDA kernel function using the NVIDIA GeForce GTX 970 graphic card was analyzed.
