Algorithms for Energy-Efficient Adaptive Wireless Sensor Networks (2015)
Abstract / truncated to 115 words
In this thesis we focus on the development of energy-efficient adaptive algorithms for Wireless Sensor Networks. Its contributions can be arranged in two main lines. Firstly, we focus on the efficient management of energy resources in WSNs equipped with finite-size batteries and energy-harvesting devices. To that end, we propose a censoring scheme by which the nodes are able to decide if a message transmission is worthy or not given their energetic condition. In order to do so, we model the system using a Markov Decision Process and use this model to derive optimal policies. Later, these policies are analyzed in simplified scenarios in order to get insights of their features. Finally, using Stochastic Approximation, we ... toggle 5 keywordswireless sensor networks – adaptive networks – diffusion – energy harvesting – dynamic programming
