Quality Driven Wireless Sensor Network

Abstract

Wireless Sensor Network is a network consisting of numerous nodes that wirelessly transmit data packets through various routing protocols that it has been based on. In this paper, the networks and its classification has been explained. Various routing algorithms based on time, location of nodes, distribution of energy between them, etc. have been touched upon. There is a short description and final comparison between the various types of protocols so as to help in deciding which type of routing method should be used in a given network based on the requirements. Following the classification and comparison, there is a simulation for a wireless sensor network for various number and degree of nodes (to show compactness between nodes). Then analysis of various parameters like the shortest path, distance traversed by the path including all the mid-nodes, distance in units, number of messages traversed in one round of simulation, etc. are done using MATLAB. Due to their versatility, ease and efficiency in operation the wireless sensor networks find an extensive use in the modern world. Some of the common areas of their uses are process management, health care monitoring, area management, defense application, air pollution monitoring, forest fire detection, landslide detection, water quality monitoring, chemical agent detection, natural disaster prevention, data logging, etc. This diverse field of application makes the study and analysis of wireless sensor network one of the hottest topic in today’s world. In short, this thesis introduces one to various wireless routing methods and concentrates on one of the most important parameter for quality improvement i.e. path; which indirectly improvises the time.
