— In a wavelength-routed optical network, a transmitted signal remains in the optical domain over the entire route (lightpath) assigned to it between its source and destination nodes. The optical signal may have to traverse a number of crossconnect switches (XCS's), fiber segments, and optical amplifiers, e.g., erbium-doped fiber amplifiers (EDFA's). Thus,(More)
—Performance of IEEE 802.11 distributed coordination function (DCF) has been studied by several authors under steady-state conditions. Behavior of DCF under transient state conditions and its modeling is important for analyzing several scenarios, such as, initialization of nodes in a wireless ad hoc network. In this paper, we present a mathematical model(More)
R ECENT developments in wavelength division multi-plexing (WDM) technology have led to a tremendous amount of commercial and research interest in WDM-based networks. Until recently, WDM has been used primarily for point-to-point long haul transmission. However, with the emergence of WDM networking components, people are beginning to design and deploy(More)
—We propose a redundant radix based number (RBN) representation for encoding and transmitting data for applications which typically utilize low cost devices and demand low power operations with simple modulation techniques like ASK, OOK and FSK. Coupled with silent periods for communicating the digit zero, this encoded communication scheme, called as(More)
Network-on-Chip (NoC) is the preferred communication backbone for modern multicore chips. However, the multi-hop data transmission using wireline interconnects result in high energy dissipation and latency. Photonic interconnects have emerged as a promising alternative to the conventional metal/dielectric based on-chip wireline interconnects. Several novel(More)
