Abstract:
In this paper, an energy efficient communication and localization framework able to manage the synchronization between nodes and to provide the localization of nomadic nodes within Nomadic Wireless Sensor Networks is presented. It is comprised of a MAC protocol based on sleep and active states and a novel localization algorithm based on Differential Direction of Arrival. Some numerical simulations was performed to show the low power consumption of the proposed protocol. Moreover, a system of fixed and nomadic nodes was implemented to test the proposed localization algorithm. The reported experiments show a mean positioning error of 0.61 m and a mean orientation error of 17 degrees within a 10 m x 10 m square space.
