Abstract:
Creating wireless sensor networks requires a different approach than traditional communication networks
because energy efficiency plays a key role in sensor networks, which consist of devices without external
power. The amount of energy used determines the lifetime of these devices. In most cases data packets are
less sensitive to delay, thus can be aggregated, making it possible to gather more useful information
reducing the energy required to transmit information. This article discusses the energy efficiency of
different Forward Error Correction algorithms and presents a method to calculate the optimal amount of
aggregation of the data packets in terms of power consumption, while taking into account the Bit Error Rate
characteristics of the wireless channel. The contribution of this paper is a general method to improve the
energy efficiency of wireless sensor networks by using the optimal amount of aggregation in case of
different FEC codes and channel characteristics. The presente
d results can be applied to any packet-based
wireless protocol.
