Abstract: Node localization is a fundamental and crucial issue for Wireless Sensor Network (WSN). In view of the limitations of rangebased techniques, rangefree localization scheme is proposed. Existing rangefree localization approaches are discussed and presented in detail, and the performance of them are compared. Finally, future works in the field of rangefree localization algorithm are pointed out.
