WSN nodes resource constrained. In order to keep the size and the cost of the nodes down, the nodes have limited processing power, memory and radio range. However, the resource constraint which has the most significant impact on many WSNs is the constraint on energy. WSN nodes are battery operated. Many wireless sensor networks are deployed in locations where battery replacement is not feasible. A node has to be discarded when the battery depletes. Energy scavenging may alleviate this problem in some sensor networks. Most WSN protocols are very conscious of the limited supply of energy, and try to conserve energy.
History records Martin Luther as a savior of Christianity. He was concerned with the well-being of the Catholic Church and its policy of granting forgiveness through indulgence rather than penance. Luther's actions were neither cinematic nor groundbreaking. The message of 95 Thesis gave the summary and expressed the feelings of many of his peers already had about the corruption of Christ's teachings.
Luther illustrated the spiritual, material, and psychological truths behind abuses in the practice of buying and selling indulgences. He was not out to pick a fight or to have his own way; his purpose was to uphold the truth, for the cause of Christ.
