Improved Routing in Wireless Sensor Networks using FLAP

摘要

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 WS N are rescue mission & monitoring the temperature of environment etc. But as WS N 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 WS N 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 DS DV protocol in WS N for the fast authentication purpose and compared its results with DS DV 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 DS DV. Comparison has done on the basis of throughput & delay time parameters.
