Abstract: Wireless Sensor Networks is an ever changing research area in the communication field. Sensor networks are crucial means for various application areas like acoustic detection, medical monitoring, military surveillance etc. Different research issues are encountered in that field often. Among them, Localization is a major issue-based concept in wireless sensor network (WSN) which needs lot of focus and remedial mechanisms. The identification of the location of the sensor nodes is a critical factor in data gathering in the sensing field. The problem faced in this area of application is identifying the physical being of the sensors their post- deployment. This paper aims at proposing certain strategies and schemes in resolving the issue of localization. The study aims at focusing the range based and range free localization techniques which may aid the current and future researchers in and technologists who intend to pursue learning of application in wireless sensor networks.
