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 [12], the proposed model has reduced energy consumption by 45%, increased the life time of
the network by 67% and increased packets sent to the BS by 15%.
