Particle Swarm Optimization and harmony search based clustering and routing in Wireless Sensor Networks

Veena Anand, Sudhakar Pandey
Pages: 1252 - 1262
Wireless Sensor Networks (WSN) has the disadvantage of limited and non-rechargeable energy resource in WSN creates a challenge and led to development of various clustering and routing algorithms. The paper proposes an approach for improving network lifetime by using Particle swarm optimization based...

Hybrid Firefly Variants Algorithm for Localization Optimization in WSN

P. SrideviPonmalar, V. Jawahar Senthil Kumar, R. Harikrishnan
Pages: 1263 - 1271
Localization is one of the key issues in wireless sensor networks. Several algorithms and techniques have been introduced for localization. Localization is a procedural technique of estimating the sensor node location. In this paper, a novel three hybrid algorithms based on firefly is proposed for localization...

Classifier Optimized for Resource-constrained Pervasive Systems and Energy-efficiency

Niklas Karvonen, Lara Lorna Jimenez, Miguel Gomez Simon, Joakim Nilsson, Basel Kikhia, Josef Hallberg
Pages: 1272 - 1279
Computational intelligence is often used in smart environment applications in order to determine a user’s context. Many computational intelligence algorithms are complex and resource-consuming which can be problematic for implementation devices such as FPGA:s, ASIC:s and low-level microcontrollers. These...

Analysis of Time – Frequency EEG Feature Extraction Methods for Mental Task Classification

Caglar Uyulan, Turker Tekin Erguzel
Pages: 1280 - 1288
Many endogenous and external components may affect the physiological, mental and behavioral states in humans. Monitoring tools are required to evaluate biomarkers, identify biological events, and predict their outcomes. Being one of the valuable indicators, brain biomarkers derived from temporal or spectral...

Modeling Users’ Data Traces in Multi-Resident Ambient Assisted Living Environments

Vahid Ghasemi, Ali Akbar Pouyan
Pages: 1289 - 1297
Modeling users’ data traces is of crucial importance for human behavior analysis and context-aware applications in ambient assisted living (AAL) environments. However, learning the parameters of the underlying model is a challenging task in multi-occupant environments; because, the anonymous users’ data...

Energy-Efficient Acoustic Violence Detector for Smart Cities

Marta Bautista-Durán, Joaquín García-Gómez, Roberto Gil-Pita, Inma Mohíno-Herranz, Manuel Rosa-Zurera
Pages: 1298 - 1305
Violence detection represents an important issue to take into account in the design of intelligent algorithms for smart environments. This paper proposes an energy-efficient system capable of acoustically detecting violence. In our solution, genetic algorithms are used to select the best subset of features...

Fuzzy-Logic-Based Application to Combat Gender Violence

José Á. Concepción-Sánchez, Pino Caballero-Gil, Jezabel Molina-Gil
Pages: 1306 - 1313
Gender violence is one of the most serious and widespread problems in our society. In dangerous cases, the use of special devices for GPS tracing is recommended in some countries. However, these devices are used only in extreme cases and have many drawbacks. This work describes a new system to combat...
