N2  - Wireless technology is the key technology to eliminate the dense wireropes from hospitals and far access to medical devices. In order to overcomethe problem of bandwidth scarcity, cognitive radio driven hospitals areintroduced and devices are divided in two categories. The first category isprimary devices and the second one is secondary devices. Primary devices hasvery high priority and their communication is vital for the hospital andpatients, so that no interference should be made with such devices. Secondarydevices are the ones which has lower priority and they can wait until theprimary devices do their communication and then, they begin to use theallocated spectrum. One of the key functions to assure that there will be nointerference is a reliable spectrum sensing method. This method should be asimple one to be able to implement it in the secondary devices. Among all thesensing methods, energy detection (ED) based spectrum sensing is very popular.In order to improve the performance of ED, double threshold ED (DTED) method isintroduced in literature. In this paper, a new algorithm is intruded for DTEDconsidering previous sensing period results in detection procedure by using amemory stick. Memoryful DTED (MDTED) improves the performance of DTEDconsiderably by only the cost of delay in secondary devices communication whichhas less value than the improvement of the detection method performance.
