摘要：The introduction of the IR-UWB Technology in the field of WSN was promising for researchers especially for its low power consumption feature. To implement such a solution, we need a suitable MAC protocol to exploit the specific features of this technology. When introducing this Technology, ALOHA was the only candidate MAC protocol. Because of the high energy consumption of ALOHA, in this paper we present WideMac, a low power medium access control protocol designed specifically for Impulse Radio Ultra Wide Band transceivers. The IR-UWB channel offers ultra low power transmissions and unmatchable robustness to multiple access interference. WideMac takes advantage of these two key properties by using asynchronous periodic beacon transmissions from each network node. To test and evaluate the performance of WideMac protocol we used PhyLayerUWBIR class developed under MiXiM platform on OMNet++ as a physical layer. For the MAC layer we developed our own class WideMacLayer.
