CHAPTER TWO NETWORKING SYSTEMS AND LOCAL AREA NETWORKS (LAN) A network is a system of two or more computers that are connected in some manner. Each computer on the network has access to the files and peripheral equipment (such as printers or modems) on all the other computers on the network. The origin of local area networks can be traced‚ in part‚ to IBM terminal equipment introduced in 1974. At that time‚ IBM introduced a series of terminal devices designed for use in transaction-processing

Throughput-Delay Trade-off for Fast Data Collection in Sensor Networks ¨ Amitabha Ghosh‚ Ozlem Durmaz Incel‚ V. S. Anil Kumar‚ and Bhaskar Krishnamachari Two primary factors that affect the data collection rate (throughput) and timeliness (delay) are: (i) efficiency of the link scheduling protocol‚ and (ii) structure of the routing tree in terms of its node degrees and radius. In this paper‚ we utilize multiple frequency channels and design an efficient link scheduling protocol that gives a constant
