Network synchronization can improve the performance of wireless networks in several ways, such as by enabling the use of slotted medium access protocols. Distributed synchronization is an appealing technique to achieve network synchronization in wireless ad-hoc and sensor networks. At the MAC layer, different signaling techniques and medium access protocols may be employed for synchronization purposes...
A novel distributed scheme that combines cooperative ARQ with the spectrum leasing paradigm is proposed and analyzed. The strategy harnesses the opportunistic gains of cooperative communications, while inherently providing a spectrum-rewarding incentive for the otherwise non-cooperative relays to assist the source's transmission. As in cooperative ARQ, the source might decide to hand over the possible...
