Indeed, WSN is composed of sensors to evaluate some physical phenomena. However, the information brought by the sensor still missed if we don't know the exact location of the event. Several localization algorithms have been proposed in order to locate the nodes in WSN. The localization algorithms are categorized into range-based and range-free techniques. The range-based techniques use either distance or time to calculate the coordinates of unknown nodes. Nevertheless, those kinds of techniques need some additional material in computation purpose. Therefore, range-based techniques present an expensive solution for positioning in WSN. Alternatively, range-free techniques may do the same task without involving additional material. But they don’t offer a high precision of localization in comparison with range-based techniques. DVHOP is the most popular range-free technique that uses the hop count method in the...

It has recently launched a growing popular class of WSN in which mobility becomes an important area of research for the WSN community. In this type of network the energy efficiency is the key design challenge. For this reason MAC layer protocols for MWSN based on IR-UWB must be energy efficient to exploit the main features of IR-UWB technology implemented in the physical layer and maximize lifetime. In this paper we present and show the good impact in term of energy consumption for an energy-efficient MAC protocol in MWSN based on IR-UWB. This MAC protocol takes advantage of these two key properties by using asynchronous periodic beacon transmissions from each network node and its duty-cycling mode.

In this paper, we propose a novel recursive kernel approach allowing to identify the finite impulse response (FIR) in non-linear systems, with binary value output observations.
