Algeria has the highest technical and economic potentials for solar power exploitation in the Middle East and North Africa region. In this paper, the focus is on the behaviour of Wireless Sensor Network (WSNs) supplied by solar panel PV connected to node via boost converter (DC/DC) controlled by maximum power point tracking (MPPT) technique, using the incremental conductance (IC) algorithm to extract maximum power. In Our present work, many tests were carried out. The WSNs are examined under sever and different temperature and irradiation variation. The obtained result is satisfactory for our (WSNs) simulated in a MATLAB/SIMULINK environment. The performances of the proposed strategy controller give a satisfactory simulation results.

Due to their small size and the high energy consumption imposed on them, the Constituents of sensor networks can not compete with computers, smart phones, tablets or other handheld terminals in terms of processing capacity of data, storage and communication. It is therefore important to be able to consider energy consumption very early in the cycle of design and development of embedded systems [1, 2]. This study focuses on a particular case of these types of miniaturized equipment these are the wireless sensor nodes. These are electronic devices communicating with each other with wireless links, and whose primary functions areto collect and transmit data in a completely autonomous way in energy. These communicating systems thus constitute the network and are called nodes sensors. They are necessarily each equipped with a catchment unit to observe the environment in which they are placed. The association of these nodes forms the wireless sensor network (WSN). Sensor nodes can be immobile or mobile. Their position in the network is not necessarily predetermined because they can be randomly dispersed in a geographical area (with an algorithm and a self-organizing protocol) or their positions can be specified and organized in a targeted area (pre-configured topology) [1, 3]. A sensor network is connected by a point to a host system. This connection point is called the well. All data collected by each node are routed to the well or collection point via a multi-hop architecture or only a jump according to the topology of the network [1, 4].
