Sensor nodes in Wireless Sensor Networks are connected via wireless links. The function of these nodes are sensing the events when placed in the environment and sending those sensed data to the base station..Many routing, power management, and data dissemination protocols have been used for WSN. The nature of WSN is similar to MANET (Mobile Ad-hoc NETwork) where nodes are mobile and communicate directly to base station. Proactive protocols like DSDV (Destination Sequenced Distance Vector) and Reactive Protocols like AODV (Ad-hoc On Demand Vector) and DSR (Dynamic Source Routing) are used during packet transmission and data forwarding.
