Abstract

This paper demonstrates the possibility of increasing energy performance in Wireless Sensor Networks by the adaptation of spreading code length. Through the experimental approach, it is shown that a WSN device can achieve higher data rate with adaptive spreading code length, which can increase the throughput and reduce energy usage. Based on our findings from experiment, we propose to actively adjust the transmission power to enable higher transmission rate, which will significantly decrease the device active time. As a result, the overall energy efficiency can be increased. Such scheme has been validated using simulation, which shows that the network life time can be increased by 36%.
