In Wireless sensor network, since the media is wireless there will be burst errors which leads to high bit error rate that affect the throughput. Wireless sensor networks drop the packets due to propagation errors that lead to retransmission traffic. This paper evaluates the effect of adaptive FEC in Wireless sensor networks. Adaptive FEC technique improves the throughput by dynamically tuning FEC depending upon the wireless channel loss. The main aim is to achieve desire throughput with less energy consumption. If the retransmission traffic decreases, that is error correction performed using adaptive FEC which maximize the throughput. The other related parameters packet delivery ratio, packet loss, delay, error rate are also being analyzed. The algorithm reduces the retransmission traffic by using Adaptive FEC technique thus improving the throughput and reduces the error rate.

The wireless communication system is well developed and lots of antennas are designed and fabricated for this application. Still, the evolution of the communication system, the performance of the antenna is required to enhance to adopt the present era. The design of the antenna is most important for the performance of the antenna. Therefore, this work is designed and developed a novel antenna design for wideband application by utilizing frequency reconfigurable technique. The proposed work utilized microstrip patch antenna for the application of wideband and the Shun-series MEMS switch is applied for switching the frequency. The proposed antenna is designed with two switches and investigated with the switching conditions like ON-ON, OFF-ON, and OFF-OFF. The performance of the proposed antenna is validated by utilizing the antenna performance metrices such as Return loss, bandwidth, gain, VSWR, and radiation pattern for each switching condition. The simulation results are shows that the proposed antenna design with shunt-series MEMS switch is effectively performed and it is most suitable for the application of wireless communication system..
