On the MAC for optimal information retrieval pattern in sensor networks with mobile access
Zhiyu Yang, Min Dong, Lang Tong, Brian M. Sadler · 2004
In sensor networks, locations of received data affect the information processing performance. In this paper, we consider how to design multiple access control (MAC) to obtain the optimal information retrieval pattern for signal field reconstruction. Taking both performance and implementation complexity into consideration, besides the optimal centralized scheduler, we propose three other MAC protocols, namely, decentralized scheduling through carrier sensing, Aloha, and decision-directed Aloha. Finally, we provide performance comparison among these protocols.
