Abstract: Wireless Sensor Networks (WSNs) are used in variety of applications. The amount of power consumed to perform the processing and communications by each node of WSNs will be related to the amount of communications between nodes, the type of applications, the type of processing core used in each node, and the type of components and technology used in the design of each node. One of the challenges associate with using such nodes in remote area is the power supplied to nodes of the WSNs. Although, using batteries could help to support the power of the sensor nodes used for some basic applications and for short period of time. However, using WSN nodes used in some applications such as border monitoring, cannot use batteries and continuous power supply to support such nodes with their working environment. In this research, we investigate this challenge for boarder monitoring application when the WSN nodes used in remote areas where it is not possible to use continuous power supply and batteries for powering such nodes.
