Improved routing in Wireless Sensor Networks using FLAP

A number of improvements in WLAN leads to the deployment of Wireless Sensor Networks. Generally, WS N is a collection of a number of sensor nodes. Because it is very easy to deploy these sensor nodes so WS N gets popularity very quickly. The main applications of WSN are rescue mission & monitoring the temperature of environment etc. But as WSN has open access so security is very important. A number of security methods are there like WEP, WPA and 802.11i. In Feb. 2014 a protocol named as FLAP was proposed as an efficient and fast authentication protocol. Various nodes in WSN communicate to one another with the help of routing protocols like AODV & DS DV. But the Delay Time due to authentication process in these routing protocols is very high. We used FLAP protocol with DSDV protocol in WSN for the fast authentication purpose and compared its results with DSDV using 802.11i for authentication. The simulation results taken through NS 3 shows that FLAP has better performance as compare to 802.11i security method with DSDV. Comparison has done on the basis of throughput & delay time parameters.
