Survey on Data Collection protocols in Wireless Sensor Networks using mobile data collectors

摘要

Wireless Sensor Networks are widely used in today's world in several applications ranging from environmental and health monitoring to military uses. Data Collection is one of the most important aspects of WSN and this topic has witnessed significant amount of research over the year. Traditionally static sensors were used in the data gathering process but later on mobile nodes were introduced with goal of achieving energy efficiency. This paper mainly deals with Data Collection techniques which uses mobile nodes. Different types of mobile nodes used in data collection have been discussed. A review of recent literature on data collection protocols using mobile nodes has also been presented.
