WideMac was presented as a novel MAC protocol designed for wireless sensor networks using impulse radio ultra wide band transceivers due to its low power consumption. Because of the luck of synchronization in this protocol, this paper will present a solution for the synchronization problem when there is only one way direction communication. | International Journal of Computer Networks and Communications Security C VOL. 1, NO. 5, OCTOBER 2013, 173–179 Available online at: ISSN 2308-9830 N C S One Way Direction Communication Synchronization for WideMac Protocol in IR-UWB based WSN Anouar Darif1, Rachid Saadane2, Driss Aboutajdine3 1,3 LRIT-GSCM Associated Unit to CNRST (URAC 29) FSR, Mohammed V-Agdal University, BP 1014 Rabat, Morocco 2 SIR2C2S/LASI-EHTP, Hassania School of Public Labors Km 7 El Jadida Road, 8108, Casa-Oasis, Casablanca, Morocco E-mail: , 2saadane@, 3aboutaj@ ABSTRACT IR-UWB technology as a next generation of the standard is a promising solutions for WSN due to its various advantages such as its robustness to severe multipath fading even in indoor environments, its low cost and complexity, and low energy consumption. To implement such a solution, we need a suitable Mac protocol to exploit the specific features of this technology. WideMac was presented as a novel MAC protocol designed for wireless sensor networks using impulse radio ultra wide band transceivers due to its low power consumption. Because of the luck of synchronization in this protocol, this paper will present a solution for the synchronization problem when there is only one way direction communication.

Though WSN is in its early stages, its impact is envisaged to be far reaching, from daily life, to remote monitoring [1] of environment, habitat, agriculture health care [2], automobiles[3], hazardous zones, disaster prone zones, defense applications to probing of planets. Moreover they can be used for monitoring as well as control. In fact, they form the basic constituent of ubiquitous sensing, communication, computing, and control [4]. Recent advances .
