Small, low cost, low power and multifunctional sensor are developed as a result of improvement in micro-electro mechanical technology. Sensors are connected via wireless medium and are used to observe various aspects of the physical world. Data sensed by these nodes needs to be agglomerated using data fusion, which requires clocks of nodes to be synchronized with each other. Existing approaches of clock synchronization are not designed keeping wireless sensor networks in mind. So there is a need to extend or redesign and develop a new way to synchronize the wireless sensor networks that is best suited to the specific needs of a sensor-network application.
