Increase the Life of the Wireless Sensor Network by using an Energy-Sensitive Threshold Cross-layer Model

Wireless sensor networks (WSNs) are advanced tools for monitoring and controlling the environment, which are powered by a limited capacity battery, and the depletion of the sensor battery leads to the end of the life of the network life. Therefore, it is crucial to use protocols that are energy efficient. In this paper, using a new cross layer model based on distance from base station (BS) and (Time Division multiple access) TDMA, the optimal use of available resources and increasing of the life time of the network are discussed. By modifying the method of selecting the cluster headers (CHs), the selection of low energy CHs, which are far from the BS, has been prevented. It also balances the transmission of data packets in different clusters, resulting in fair energy consumption between sensors. By comparison with the ATEER model in [۱۲], the proposed model has reduced energy consumption by ۴۵%, increased the life time of the network by ۶۷% and increased packets sent to the BS by ۱۵%.
