Light trails, a fairly recent optical networking architecture for LAN and MAN, and possibly WAN applications, can support both optical unicast and multicast. In this paper we consider routing both types of traffic in a survivable light trail network with multiple wavelengths. The algorithm supports multi-hop routing where traffic may use up to two light trails to reach its destination. An ILP is developed...
Energy management is the key issue in the design and operation of wireless network applications like sensor networks, pervasive computing and ubiquitous computing where the network is primarily driven by battery-powered embedded devices. This paper studies network coding as an energy minimization technique. Network coding reduces the energy consumption by minimizing the number of transmissions required...
This paper considers link based protection where backup capacity is preconfigured into various patterns. When the amount of backup capacity available on a link is constrained, the choice of patterns under consideration can determine if a given network is protectable. This paper gives an ILP that can be used in calculating preconfigurations, even when p-Cycles with p-lines or non-simple p-Cycles alone...
