This paper examines the effect of different information access strategies on power consumption and information reliability, considering the wireless sensor network as the source of information. Basically, the paper explores three different access strategies, namely; reactive, periodic and hybrid and computes power consumption and mismatch probability  in each of these access strategies. Based on our study, we make some recommendations when and where, which access strategy is suitable depending upon the application's requirements and network behavior. It also provides the model implementation results, validating the analytical models being used. At last, the paper highlights how system can adapt with the application's requirements (power and mismatch probability) by adapting sampling rate.
