Abstract
The evolutions in proficient resources, route discovery protocols, simplicity in hardware design, and other aspects have enabled the wireless sensor networks to have a steady rise in the recent decade. Lately, people started favouring moveable devices in the place of static devices, which brought moveable sensor network into focus. Location information continuously plays a key role in Mobile wireless sensor network (MWSN) and exact location identification has continuously been a test for moveable sensor devices. Installing GPS receivers for every device would also solidify network installation cost for a large network. The unavailability of GPS in covered and underground surrounding has put the installation of GPS into problem. This makes the sensor devices to detect its location coordinates or location reference without using GPS, and is achieved with the help of a special device that knows its location coordinates and protocols, called anchor device. The authors' goal is to confer diverse location identification techniques used by moveable sensor devices to detect their location information. Complications and future issues have also been deliberated.
