Lifetime Analysis of a Slotted ALOHA-Based Wireless Sensor Network Using a Cross-Layer Frame Rate Adaptation Scheme

Cross-layer design has been widely used in wireless sensor networks, especially to improve the network lifetime, as can be seen in the literature. In this paper, a cross-layer solution is combined to a transmission advertisement scheme to improve a slotted ALOHA-based wireless sensor network throughput and lifetime. This medium access method scheme has been chosen because it does not add protocol information to be transmitted with data bits, reducing transmission overhead when compared to other medium access methods. Finally, the combination of a cross-layer design and the advertisement scheme has proven to increase the network throughput by more than 10% and to double the network lifetime.
