Evaluating the Energy Overhead Generated by Interferences within the 2.4 GHz Band for a Hybrid RFID Network

Energy efficiency is one of the key elements in the design of pervasive wireless communications systems. This metric can be influenced by several factors, one of which is the presence of interference in the already overcrowded 2.4 GHz ISM Band. A quantitative evaluation of the energy overhead generated by interference in the above mentioned frequency band is a first step in the optimization process meant to reduce this overhead. Through this paper the authors have designed and implemented a test bed for measuring and analyzing the impact that wireless sources of interference (i.e. Wi-Fi) have on the energy efficiency of a pervasive communications system.
