In this study, we investigate the correlation between security and spatial resolution -a measure of service quality- in cluster-based wireless sensor networks (WSN). We analyze the tradeoff between these two concepts resulting from the limited channel capacity. We propose a method based on combinatorial optimization to determine the best tradeoff between security and spatial resolution for cases where network capacity is not sufficient to support required levels. The proposed method involves formulation of an optimization problem by utility maximizing approach and its solution by a heuristic algorithm providing minimal operational complexity. We also present some numerical results obtained by application of the proposed method to a sample sensor network. The numerical results demonstrate the effect of utility function parameters on the optimal solution.

Tradeoff analysis and optimization of security and spatial resolution for sensor networks Tomur, Emrah; Erten, Y. M. (2007-03-16) In this study, we investigate the correlation between security and spatial resolution -a measure of service quality- in cluster-based wireless sensor networks (WSN). We analyze the tradeoff between these two concepts resulting from the limited channel capacity and propose a method to determine the best tradeoff between security and spatial resolution for cases where network capacity is not sufficient to support required levels.

Security and service quality analysis for cluster-based wireless sensor networks Tomur, Emrah; Erten, Y. Murat (2007-05-25) In this study, we analyze security and quality of service (QoS) issues in cluster-based wireless sensor networks (WSN). Taking spatial resolution as the main QoS metric and limiting the security definition to data integrity and authentication, we present a control strategy to maintain desired QoS and security levels during the entire operation of a cluster-based sensor network. Besides, our proposed strategy considers some other WSN QoS attributes such as coverage, packet collision and system lifetime. It p...
An Analysis for the Correlation of Coverage and Spatial Resolution for Wireless Sensor Networks Tomur, Emrah; Erten, Y. Murat (2007-12-10) In this study, we investigate the interactions between coverage and spatial resolution for cluster-based wireless sensor networks (WSN). We present an approximate probabilistic analysis for the mentioned correlation and verify this analysis by simulation. Our analysis includes the k-coverage case.
Security and quality of service for wireless sensor networks Tomur, Emrah; Bilgen, Semih; Department of Information Systems (2008) Security and quality of service (QoS) issues in cluster-based wireless sensor networks are investigated. The QoS perspective is mostly at application level consisting of four attributes, which are spatial resolution, coverage, system lifetime and packet loss due to collisions. The addressed security aspects are message integrity and authentication. Under this scope, the interactions between security and service quality are analyzed with particular emphasis on the tradeoff between security and spatial resolu...
Efficient Tracking of Multiple Objects in Wireless Multimedia Sensor Networks Oztarak, Hakan; Akkaya, Kemal; Yazıcı, Adnan (2013-01-01) Wireless Multimedia Sensor Networks (WMSNs) are characterized by large number of resource constrained camera sensors. In remote surveillance applications, such resource constraints necessitate the design of lightweight solutions for traditional problems such as object localization and real-time tracking. In this paper, we propose an energy-efficient object localization and multiple object tracking scheme for WMSNs. The object localization is performed by individual camera sensors. For that purpose, the appr...
