WDM Networks and Systems, Network Planning and Management The demand for ever more capacity over the lucrative long-haul routes coupled with the need for higher reliability is pushing optical technology towards its limits. WDM systems allow upgrading of existing core networks and offer new opportunities for long-haul systems design towards ultimate terrabit systems. The prospect of an all-optical layer offers new possibilities for dynamic management of capacity and protection switching. Papers published in these proceedings: *Explore business opportunities for WDM systems *Highlight recent advances in key technologies such as add drop multiplexers, arrayed planar waveguides, and broadband EDFAs *Present new bandwidth management techniques *Push the transmission limits to the technology by minimising dispersion, non-linearities and intermodulation effects, and charts the way to soliton systems.

SICON '97 is the fifth conference since the first SICON, organized in 1989. It aims to provide a forum for the presentation and dissemination of results in computer communications and networking research.SICON '97 has a single-track technical programme comprising less than half of the total number of full papers that were submitted to the International Programme Committee of well-known and respected experts for review. The technical programme covers original research and development in the following areas: high speed networks, ATM, optical networks, wireless and mobile networks, performance measurement and modeling, network security, resource sharing and quality of service, internetworking, network architecture and protocols, and distributed computing.

Wireless ad hoc networks are different from wired networks by the multitude of data packet loss situations they are subjected to. This is due to the characteristics of wireless channel that might obstruct the proper reception of data packet at the destination end. In some case, these vulnerabilities of wireless channel can result in a complete link failure. Although link failure is of low probability in wired networks, it is rather common in wireless networks. The volatility of communication channel is a typical problem with wireless links, which is not the case with wired cables. TCP is a transport protocol that aims at ensuring high reliability and guarantying reception of data packets. However, TCP was designed for wired networks to address congestion, which is the main cause for data packet loss in wired networks. Therefore, other types of data packet loss encountered in wireless networks are prone to misinterpretation by TCP, which will lead to TCP performance degradation within the network. To overcome the performance limitation of TCP when used within ad hoc networks, the aim of this thesis is twofold. First, a complete performance study of TCP over ad hoc networks is achieved. This evaluation concerns two performance metrics: the achievable throughput and the energy consumption of TCP within ad hoc networks. This study allows identifying the potential room of improvement to enhance TCP efficiency in ad hoc networks. Second, we propose a new TCP variant, TCP-WELCOME that optimizes the performance of TCP in ad hoc networks through its ability to distinguish among, and efficiently deal with, different data packet loss situations, within ad hoc networks.
