1. Introduction
Device free localization (DFL) with wireless sensor networks can be applied to many scenarios including future healthcare, smart building and security applications [1,2]. DFL technologies are distinct from traditional localization methods in that they do not assume the targets wear any electronic devices such as RFID tags. This ‘noninvasive’ property is especially useful for surveillance systems where the intruders might be device-less. Typically, DFL technologies utilize the attenuation of wireless links caused by human presence to locate people. The attenuation of a wireless link can be characterized by the Received Signal Strength (RSS) change. DFL with wireless sensors can be implemented conveniently because RSS can be easily measured from most sensor platforms. Existing DFL systems [2–5] mainly target at high localization accuracy. Therefore, various RSS dynamic measures have been proposed to characterize the attenuation caused by human presence, such as difference of mean RSS readings [2], variance of RSS read-ings [3] and the Kullback–Leibler divergence (KL-divergence) of two RSS reading distributions [6]. A better measure for RSS dynamic values leads to a better localization accuracy. However, to calculate the proposed RSS dynamic values, raw RSS readings from all links should be sent to the base station. Higher traffic consumes the energy of every sensor much more quickly, resulting in a shorter network lifetime. Unfortunately, this important issue has not been addressed in existing DFL systems. We aim at improving the energy efficiency of DFL systems without sacrificing the localization accuracy. This is achieved through the following observations. First, RSS readings in most platforms (such as the TelosB platform [7]) are represented by an 8-bit integer. We can finish a round of RSS collection much more quickly and put the network in sleep mode if the RSS dynamic values can be calculated locally in sensors and represented by fewer bits. Second, not all wireless links are necessary in tracking a moving person since a person can only attenuate a few links of the system. Accordingly, many sensors can turn off their radio modules to save energy if we can predict the location of the person.
