One Realization of Low-Power Wireless Sensor Node

In this paper a practical realization of sensor node is described. Performance analysis for new implemented protocol is also described. In proposed model a sensor network is organized into local clusters. Within the cluster a nodes are battery powered and fixed cluster-head or gateway node have large power supply. In this paper a data exchange between sensor node and cluster head only bee analyzed. Data exchange and number of nodes in cluster is effect statistical analysis based upon in Poisson distribution. Minimum number of trials needed to be sure that the packet reaches the receiver with prescribed probability for varying bit error rate is discussed, too. Lastly, for our hardware solution and example application for temperature measurement energy consumption analysis is given. Comparative results display a power consumption reduction of one order of magnitude regard to previous solution.
