Design and implementation of an energy efficient mac protocol for wireless sensor networks

Wireless Sensor Network is a popular technology in the different fields nowadays and is getting more important day after day. This network contains nodes which is used to in wireless sensor network and is organized oneself. Sensor nodes generally are worked with a battery to be placed easily in the network. So, energy effeciency hold especially so critic significance for region where is reached difficultly. Therefore, this new study covers nodes adaptive sleeping, providing constant transmission, and using nodes energy efficiently for energy effeciency which is so important issue of wireless sensor network. The highest energy wastages status is determined in this study. This study offers solutions for that status and practiced both of simulation and application. This study embraces that fee nodes are passed in the sleeping status to prevent the highest energy wastage status. Application for transferring sleeping status in the nodes is made adaptively. Two type transmissions are achieved in the BSC-MAC protocol. They are seperated as root and resource. Resource nodes produce data and convey it through root nodes to base stations. Sleeping periot's time synchronizing is achieved with two different methods adaptively to prevent failing transmission between root and resource or in themself. As a result, BSC-MAC protocol is more efficient method than others in terms of energy efficiency and also transmission in the BSC-MAC protocol is well. Also BSC-MAC protocol achieves a fair access to the media.
