| Abstract: | This paper firstly presents the principle of two important contention-based MAC protocol of WSN（IEEE802.11 and S-MAC）and then discusses the plan to achieve the test-bed in detail from the aspects of the overall architecture and operating environment of test-bed.The paper,to realize IEEE802.11 and S-MAC protocol,describes the definition of communication interface and the technology of component reuse exactly,and then explains their operational flows through the aspect of running state.In the end the paper contrastively analyzes IEEE802.11 and S-MAC in different areas according to the data from the experiment.The results of experiment reflect the actual performance of protocols,and it can actively promote the study of MAC protocols for WSN. |
