VIGILANT+: mission objective interest groups for wireless sensor network surveillance applications

Abstract

In this paper a system termed VIGILANT + is outlined, which utilises situation awareness for the purposes of enabling distributed, autonomic, sensor management, so that savings on consumption of network resources can be achieved. VIGILANT + is a novel proposition allowing deployed, unattended, wireless sensor nodes to selforganise into dynamic groups and self-manage their transmissions efficiently, according to a current common mission objective. Firstly, a distributed situation assessment system named PORTENT models, detects and characterises potential situations occurring within an uncertain environment, using the metric, quality of surveillance information (QoSI). Secondly, a Bayesian Belief Network (BBN) is utilised to understand and analyse the significance associated with the potential situation, primarily to enable deployed sensors to selforganise and assign themselves to mission objectives autonomously. Thirdly, a system is introduced for distributed autonomic transmission control, which enables the efficient management of sensor network resource consumption. Simulations have been undertaken to verify the integrated VIGILANT + concepts and to demonstrate the effectiveness of the proposed approach in improving network efficiency, without compromising the presentation of mission surveillance utility.

Distributed collaborative surveillance system based on leader election protocols

“…Moreover, its value has a similar trend to that of the former metric. Finally, by Tables 1 and 2, we find that for different situations, most standard deviation values fall in the range [0,3]. Hence, we can conclude that in our simulation experiments, regardless of how many moving objects enter the monitoring area, the collaborative mechanism in our system can make the monitoring devices cooperative together to assign their cameras to all moving objects as evenly as possible.…”

“…Hence, a variety of visual surveillance systems has been designed to satisfy different aspects, e.g. industry, commerce, law, military, and so on [1][2][3][4]. However, traditional visual surveillance systems can only record video information passively and inflexibly, incurring high overhead upon recording.…”

“…To enhance the ability of visual surveillance systems further, beside the computer vision technology, researchers began to combine visual surveillance systems with other technologies, like multi-sensor surveillance, distributed computation, embedded system, and so on [1][2][3][4][5][6][7][8][9][10][11][12][13]. These novel visual surveillance systems benefited much from the aforementioned technologies because the advantages of these technologies were added to these systems.…”

Clock synchronization protocol for wireless sensor networks with bounded communication delays

“…The inherent multidisciplinary nature of WSNs has attracted scientists coming from different research areas, from networking to robotics. Their application ranges from surveillance and coverage (Gasparri, Krishnamachari, & Sukhatme, 2008;Ghataoura, Mitchell, & Matich, 2011), structural health monitoring (Harms, Sedigh, & Bastianini, 2010;Torfs et al, 2013), and industrial process control (Hancke, 2013;Ramamurthy, Prabhu, …”

Networking and application interface technology for wireless sensor network surveillance and monitoring

“…In this section, we present our developed VIGILANT + system [5] derived from our previous work [6], which adopts a distributed SA approach to allow UGS self-management, as shown in figure 2. The performance evaluation scenario conducted in [6] to support our current VIGILANT + work concerns monitoring a single mobile threat moving at a constant velocity, v m/s, with a diagonal trajectory.…”
