摘要
In this paper, we proposed an adaptive low latency MAC protocol for sensor networks based on cross-layer architecture, named LLS-MAC (Low Latency Sensor MAC). The new protocol is inspired by S-MAC. The advancement of LLS-MAC in packet end-to-end delay is mainly due to the continual data transmission scheme presented in this paper. For achieving this scheme, a cross-layer design approach is adopted in LLS-MAC. Simulations have been done to evaluate the performance of the proposed new protocol, by which we can find out that LLS-MAC can really reduce packet end-to-end delay greatly in case of busy networks compared with S-MAC.
