With the growing of wireless network technology researchers find that Wireless Sensor Network (WSN) is one the newest technology to make the life more comfortable and interesting. Security is needed to ensure the communication between the sensor node which is already a part from the same network and not outside intruder or attacker. To guarantee implementing the security in wireless sensor network, there are many protocols coming into the picture; this project selects the recent two protocols SRTLD and BIOSARP for critical analysis and investigation. After comparing the power consumption and delivery ratio to guarantee long life time for sensor node and to ensure the wireless senor network is working probably.
