Performance Evaluation of IEEE 802.15.4 PHY based Sensor Networks with MCTA

Abstract

IEEE 802.15.4 is the standard that is specially developed for low cost, low data rate and low power consumption wireless network. IEEE 802.15.4 is a standard which specifies the physical layer and media access control for low-rate wireless personal area networks (LR-WPANs). This paper provides a description of the performance evolution of IEEE 802.15.4 PHY based sensor network with multi capacity transmitter algorithm. In this paper, we want to work to improve the efficiency and performance of data transmitter. Presently IEEE 802.15.4 standard based device works with single transmitter that transmits and receives data in one to one manner. In proposed device, all three transmitters are kept in many to many transmission manners but transmit and receive data in one to one manner and automatically switch from first transmitter to second and second to third and so on as required. Existing transceiver device can be failed some time due to data load and power failure. To overcome this problem, we propose multiplicative capacity transmitter device. In this mechanism, we propose three transmitters in a single device and all the three transmitter have double and triple capacity to sense and transfer data to work in proper manner from previous one. If first transmitter is not working properly then second transmitter, which is having double capacity from its previous one, will be automatically active and will work smoothly. This is specially designed for future purpose in which transmitter failure problem can be occur.
