Abstract
Wireless Computer Networks and Associated Energy Efficient Protocols
Highlights
AD hoc networks and various sensor networks are crucial in network centric warfare
We take a theoretical approach to analyzing the amount of energy consumed by general wireless ad hoc networks in which links are subject to block fading and network topology varies in time
Irrespective of the fact that whether it is a proactive networking or reactive networking there always is some amount of energy dissipation which must be controlled
Summary
AD hoc networks and various sensor networks are crucial in network centric warfare. The movement of nodes, the energy constraints, and the scale of the network all impose formidable design challenges. By proactive networking we mean that all links between nodes and all routes between source-destination pairs are maintained and updated regardless of the data traffic. The reactive networking, in contrast, assumes no predetermined routes, nor does it maintain links at the physical layer. It finds a route only when a message is to be delivered from source to destination and establishes a link just before the transmission is to be scheduled. The need for energy efficiency is a problem that derives from the constraints imposed by battery capacity and heat dissipation which are opposed by the desire for miniaturization and portability.
