Abstract
Los recientes desarrollos en la integración de componentes electrónicos han permitido la introducción de una nueva tendencia en el campo de la telemetría y de las comunicaciones: las redes de sensores inalámbricas. Mediante esta nueva tecnología se obtienen los beneficios que proporcionan las redes de sensores junto a una mayor libertad a la hora de situar los sensores en las proximidades del objetivo. En las redes de sensores inalámbricas, el encaminamiento es un aspecto crítico y de importancia. Este documento realiza un estudio de este tipo de redes y de los protocolos de encaminamiento que pueden ser usados en ellas. Además, ofrece una maqueta de simulación en la cual se puede caracterizar el funcionamiento de cualquier protocolo de encaminamiento que se utilice en una red de sensores inalámbricos ad-hoc. Dicha maqueta ofrece una serie de ventajas frente a los simuladores existentes en el mercado, siendo la más importante la facilidad de implementar cualquier protocolo en ella. El presente proyecto trata de caracterizar el protocolo AODV haciendo uso del entorno de simulación implementado. Este protocolo es utilizado por el estándar Zigbee, siendo dicho estándar el más usado en el ámbito de las redes de sensores inalámbricas. En las simulaciones del protocolo AODV se muestran una serie de métricas que pueden ser usadas para las comparaciones de los distintos protocolos implementados en el entorno de simulación. El objetivo fundamental de este proyecto será ofrecer un entorno de simulación adecuado para caracterizar el funcionamiento de los protocolos de encaminamiento en redes inalámbricas de sensores ah-hoc, facilitando la implementación de estos protocolos mediante el uso de dicho entorno. En el estudio del estado del arte de los protocolos de encaminamiento se propone un gran número de éstos que pueden ser implementados en la maqueta de simulación diseñada. _________________________________________________________
Recent developments in the integration of electronic components have enabled the introduction of a new trend in the field of telemetry and communications: wireless sensor networks. By means of this new technology it is possible to get the benefits that sensor networks provide and a greater freedom for locating the sensors near to the target. In wireless sensor networks, routing is critical and important. This paper makes a study of this type of networks and routing protocols that can be used in them. In addition, it offers a simulation environment which can characterize the performance of any routing protocol that is used in a wireless sensor network ad-hoc. This simulation environment offers a number of advantages over existing simulators on the market, the most important being the ease of implementing any protocol in it. This project try characterize the protocol (AODV) using the simulation environment implemented. This protocol is used by the Zigbee standard, being the most used standard in the field of wireless sensor networks. In the simulations of AODV protocol are shown a series of metrics that can be used to comparisons of the different protocols implemented in the simulation environment. The primary objective of this project will be provide a simulation environment to characterize the operation of routing protocols in wireless sensor networks ah-hoc, facilitating the implementation of these protocols through the use of that environment. In the study of the state of the art of routing protocols are proposed a great number of protocols that can be implemented in the simulation model designed.
