This paper presents the network output load at the Fully Functional Device (FFD) and Reduced Functional Devices (RFD's) of IEEE 802.15.4 for different modulation schemes. From the simulations it is revealed that Minimum Shift Keying (MSK) is best suited for all types of devices in 802.15.4 for wireless sensor networks (WSNs) if the network output load is to(More)
The energy resolution of the barrel part of the CMS Electromagnetic Calorimeter has been studied using electrons of 20 to 250 GeV in a test beam. The incident electron's energy was reconstructed by summing the energy measured in arrays of 3×3 or 5×5 channels. There was no significant amount of correlated noise observed within these arrays. For electrons(More)
