Based on fast wake-up ONU, an intra-cycle sleep mechanism is proposed to perform energy conservation with little degradation of QoS even under heavy traffic load in 10G-EPON. Both mathematical analysis and comparative simulation are performed.
In many medium access control (MAC) schemes for wireless networks, an Acknowledgment (ACK) packet is transmitted from the data receiver to the data sender to announce the successful reception of the data packet. Such a protocol requirement may become a system weakness when malicious nodes attack these wireless networks. In this paper, we demonstrate the effects of such a Jamming ACK (JACK) attack...
