ABSTRACT: Interference is one of the fundamental challenges in the wireless communication. Reducing the network interference leads to fewer collisions of communication signals and thus packet retransmission will be decreased. Reducing the interference decreases the delays and the power consumption indirectly, thus it makes an increase in the network lifetime. Therefore, How to choose the sensor nodes and the amount of energy consumption are very important in routing methods. In this paper, the idea of using gravitational search algorithm has been proposed in order to reduce the interference and increase the lifetime of the wireless sensor networks. The proposed algorithm selects a link based on GSA among from the nodes that are candidates in energy efficient space with the minimum interference. The simulation results indicate that the proposed algorithm shows better performance compared to EIGR algorithm in terms of signal to noise ratio –plus- Interference and lifetime.
