|An Acknowledgment-Based Approach for the Detection of Routing Misbehavior in MANETs
||We study routing misbehavior in MANETs (Mobile Ad Hoc Networks) in this paper. In general, routing protocols for
MANETs are designed based on the assumption that all participating nodes are fully cooperative. However, due to the open structure

||Broadcast is a fundamental operation in wireless networks, and nai¨ve flooding is not practical, because it cannot deal
with interference. Scheduling is a good way of avoiding interference, but previous studies on broadcast scheduling algorithms all...

the MAC layer. To address these problems, the ready-to-send
and clear-to-send (RTS/CTS) dialogue has been proposed in
the literature. Ho...
