In this paper, a novel method is proposed to dimension a randomly deployed heterogeneous Wireless Sensor Network (WSN) of minimum monetary cost satisfying minimum coverage and minimum lifetime requirements. We consider WSNs consisting of two different types of nodes clusterheads and ordinary sensor nodes, randomly deployed over a sensing field. All devices are assumed to be stationary and have identical sensing capabilities. However, the clusterheads are more energetic and powerful in terms of processing and communication capabilities compared to sensor nodes. For such a network, finding minimum cost WSN problem is not a trivial one, since the distribution of the mixture of two different types of devices and the batteries with different initial energies in each type of device primarily determine the monetary cost of a WSN. Therefore, we formulated an optimization problem to minimize the monetary cost of a WSN for given coverage and lifetime requirements. The proposed optimization problem is solved for a certain scenario and the solution is validated by computer simulations.

Lightweight Object Localization with a Single Camera in Wireless Multimedia Sensor Networks Oztarak, Hakan; Akkaya, Kemal; Yazıcı, Adnan (2009-12-04) Advances in wireless multimedia sensor networks (WMSNs) stimulated interest in designing lightweight solutions in terms of processing and energy consumption for traditional problems due to severe resources constraints on camera sensors. Finding the exact object location is one of such traditional problems which has been well studied in the past. However, the proposed solutions mostly involve complex processing with multiple cameras and thus cannot be applied to surveillance applications which need to be dep...
Improving performance of network intrusion detection systems through concurrent mechanisms Atakan, Mustafa; Şener, Cevat; Department of Computer Engineering (2003) As the bandwidth of present networks gets larger than the past, the demand of Network Intrusion Detection Systems (NIDS) that function in real time becomes the major requirement for high-speed networks. If these systems are not fast enough to process all network traffic passing, some malicious security violations may take role using this drawback. In order to make that kind of applications schedulable, some concurrency mechanism is introduced to the general flowchart of their algorithm. The principal aim is...
A cross-layer protocol for wireless sensor networks Akyildiz, Ian F.; Vuran, Mehmet C.; Akan, Ozgur B. (2006-03-24) Severe energy constraints of battery-powered sensor nodes necessitate energy-efficient communication protocols in order to fulfill application objectives of wireless sensor networks (WSN). However, the vast majority of the existing solutions are based on classical layered protocols approach. It is much more resource-efficient to have a unified scheme which melts common protocol layer functionalities into a cross-layer module for resource-constrained sensor nodes. To the best of our knowledge, to date, there...
A Kalman Filter Based Approach for Light Flicker Evaluation of Power Systems Kose, Neslihan; Salor, Ozgul; Leblebicioğlu, Mehmet Kemal (2009-01-01) In this paper, a Kalman filtering based approach is proposed to measure the light flicker of the electricity transmission systems. Analytical expressions of the instantaneous light flicker sensation are obtained beginning from a voltage waveform and these expressions are used to obtain a flicker estimation method based on the IEC (International Electrotechnical Commission) flickermeter. In the proposed method, the frequency domain components of the waveform are obtained by Kalman filtering and these compone...
A P2P based failure detection model for distributed systems Kavuklu, Celal; Doğru, Ali Hikmet; Department of Computer Engineering (2006) A comprehensive failure detection model is proposed to detect service failures in asynchronous distributed systems. The proposed model takes advantage of P2P technology to provide required functionality. When compared to similar studies in failure detection, the presented failure detection model is more autonomous in resolving service dependencies, embodies more flexibility in providing different failure detection functions (like unreliable failure detectors, membership services) and offers more security. A...
