摘要：
Large ad hoe and sensor networks impose stringent constraints on cost and energy efficiency. Impulse-based ultra wideband (I-UWB) is an attractive radio technology, and we have developed four medium access control (NUC) protocols to support I-UWB radios in such networks. The four NUC protocols are multichannel ALOHA (M-ALOHA), multichannel pulse sense multiple access (M-PSMA), PSMA with collision avoidance (PSMA/CA), and busy signal multiple access (BSMA). These MAC protocols permit random distributed medium access with no central point of failure. This paper characterizes the energy efficiency, throughput, and delay of the four protocols. The results suggest appropriate application scenarios for each of the protocols.
