Abstract
Wireless sensor networks (WSNs) has made a remarkable improvement in hardware design, resource efficiency, communication and routing protocols, and other aspects thereby, making it widely used in the current decade. Nowadays, people started preferring mobile nodes in the place of static nodes, which brought mobile sensor network into focus. Current position information always shows a key role in Mobile wireless sensor network (MWSN) and accurate localization has always been an encounter for mobile sensor nodes. Installing GPS receivers for each node would also increase network installation cost for a large network, thereby making the sensor nodes to identify its own location coordinates or location reference without using GPS, and is achieved with the help of a special node that knows its location coordinates and protocols, called anchor node. The localization process suffers some setbacks due to adversary nodes. The adversary nodes make the location process tedious by giving false location references. This paper's goal is to confer different localization techniques used by mobile sensor nodes to identify their location information and the attacks confronted during localization. Problems and future issues have also been discussed.
