Implement Adaptive Modulation Technique in Wireless Sensor Network to Reduce Bit Error Rate
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 10
Abstract
A wireless sensor networks a collection of nodes are organized in cooperative network. These nodes are the sensor nodes which is communicate over the wireless medium. The wireless medium may either of radio frequencies, infrared or any other medium, of course, having no wired connection. These nodes are deployed in a random fashion and they can communicate among themselves to make an ad-hoc network. There are several issues in wireless sensor networks like battery degradation, scalability. When data transfer from source to sink their signal strength become weak due to network interferences. To regain their strength a modulation should be needed which increase its strength. So to overcome this problem a novel technique will be proposed which is based upon adaptive modulation. Adaptive modulation helps to increase signal strength and improves bit error rate.
