Collaborative Localization in Wireless Sensor Networks
Authors
Abstract
Determining the localization of nodes in a Wireless Sensor Network is a very important task, which involves collaboration between nodes. Localization is a fundamental service since it is relevant to many applications and to the network main functions. Collaboration is essential to self-localization, so that localization can be accomplished by the nodesthemselves, without any human intervention. In this paper, we first analyze the key aspects that have to be considered when designing or choosing a solution for the localization problem. Then, we present the types of current localization algorithms, making a broad comparison among the most relevant algorithms. With this comparative analysis, we aim at identifying a more complete algorithm able to adapt itself to a wide variety of possibilities (number and density of nodes, obstacles and terrain irregularities, network topology, node mobility, etc.).
