Simulación de una red de sensores inalámbricos con topología multi-hop, para el estudio de la propagación y distribución de la señal a través del algoritmo de dijkstra, utilizando el software matlab.

Abstract

In this degree thesis work was designed and implemented in the matlab software. A simulation model of wireless networks with multi-hop topology was proposed. The sensor network realized the propagation and the distribution of the signal through the mathematical algorithm of short paths of dijkstra.

Difficult access, long distances, difficulty of terrain and environment, makes it difficult to implement structured cabling to interconnect equipment, machines, monitor and control a large number of processes such as measuring temperature levels, calculating distances, counting and detection of telluric movements. The advance in communications provides the opportunity to replace the structured wiring through the deployment of a wireless sensor network, which is presented as a viable, low cost and highly reliable in the monitoring, control and sensing of the different physical parameters , statistics and metereologicos of the different companies located in places of difficult access.

The main contribution of this titration work is that by means of the simulation the number of nodes to be deployed can be placed from two to four hundred, obtaining a sparse or dense network. In which an optimization will be obtained through the implementation of the Dijkstra algorithm, obtaining in this way between the master node and the slave nodes the connection, communication and transmission of data by means of the shortest path, saving time and energy consumption.
