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 provides sufficient coverage by statistical means and minimizes packet loss due to collisions by employment of a slotted MAC (media access control) scheme. It also tries to maximize the operational lifetime of the sensor network by a power conserving scheme which make all sensors participate equally. In this study, we also determine the best tradeoff between security and spatial resolution.

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...
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. We also present some numerical results obtained by application of the proposed m...
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 Spatial Resolution Optimization for Cluster-Based Wireless Sensor Networks Tomur, Emrah; Erten, Y. M. (2008-07-05) 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 ...
Finding sensing coverage and breach paths in wireless sensor networks Onur, Ertan; Delic, H (2004-01-01) Most of the recent studies on wireless sensor networks deal with the communication coverage. However, for the surveillance wireless sensor networks, sensing coverage is an open research area. In this paper, the sensing coverage area of surveillance wireless sensor networks is studied. The sensing coverage is determined by applying Neyman-Pearson Detection Model and Dijkstra's shortest path algorithm is applied to find the weakest breach path. Although individually not enough, breach probability is an approp...
