In this paper, we examine the effects of a power saving scheme in Passive Optical Networks (PON). Buffers in network equipment have been a cause of concern since they consume significant power. In a PON, the Optical Network Unit (ONU) buffers client node packets before forwarding to the Optical Line Terminal (OLT). We propose a scheme that reduces or eliminates buffers in the ONU thereby providing...
We propose and analyze a hierarchical agent-based secure multicast (HASM) algorithm for efficiently supporting secure mobile multicast in wireless mesh networks, with design considerations given to minimize the overall network cost incurred by multicast packet delivery, mobility management, security key management, and group membership maintenance. HASM dynamically maintains a group of multicast agents...
