Abstract :
A cross-layer scheme, namely ALOHA with Collision Resolution (ALOHA-CR), is proposed for high throughput wireless communications in a cellular scenario. Transmissions occur in a time-slotted ALOHA-type fashion but with an important difference: simultaneous transmissions of two users can be successful. In this paper, throughput and service delay analysis is provided and the analytical results are validated on the Wireless Open Access Research Platform (WARP) testbed containing software defined radio (SDR) testbed. Both analysis and experiments indicate that ALOHA-CR leads to significant increase in throughput and reduction of service delays.
