EXPANSION OF LIGHTWAVE NETWORK ROOKNET - TDMA ROOKNET

Lightwave networks based on optical wavelength division multiplexing ( WDM) have been considered promising for high-speed communication. Such lightwave networks are divided mainly into two groups according to th e number of hops required for packets to arrive at their destinations: single-hop networks and multihop networks. The authors have already p roposed a lightwave mesh network RookNet, which allows packets to arri ve at any node at most in two hops, by taking advantage of both single -hop and multihop networks, and analyzed its performance. This paper p roposes a scheme to enlarge the RookNet without increasing the number of receivers per node and analyzes its performance. Specifically, the TDMA scheme is used in which a pair of nodes share a channel and emplo yed sequentially. As a result, the proposed RookNet, referred to as th e TDMA RookNet, accommodates about three to four times as many nodes a s the original one.
