“…"Fast" response is based on single sensory observations modelled using standard signal detection theory [17]. "Slow" response is modelled by integrating sensory samples over time, using the sequential probability ratio test (SPRT), in terms of the Neyman-Pearson (NP) lemma [18]. The SPRT tests two alternative hypotheses, representing the presence and absence of threat while updating the relative likelihood ratio of each as new sensory samples arrive.…”

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.

“…In general, dense and highly redundant sensor deployment is preferred to ensure robustness. A probabilistic approach is presented for determining the number of sensors necessary to operate at a desired probability of detection with and without considering the sensor correlations in [4] and [9], respectively.…”

When wireless sensors are used to keep an area under surveillance, a critical issue is the quality of the deployment from the sensing coverage viewpoint. In this paper, we propose several quality measures, which indicate if the deployment provides sufficient coverage, or whether redeployment is required or not. The terrain is modeled as a grid and the placement of the sensors is uniformly distributed. Neyman-Pearson detection is utilized to determine the effects of false-alarm and signal characteristics on the measures.
