Energy Conservation Protocols for Wireless Data Networks (Paperback)


This thesis studies the use of wireless medium access control (MAe protocols to conserve energy in wireless portable radios, in both centrally controlled and ad hoc networks. In the former, it compares methods of scheduling, methods of announcing schedules, and various access techniques. It concludes that there are two primary objectives. First, MAC protocols should put nodes not participating in data exchanges into a low energy state. Second, information that enables these nodes to enter these states must be provided quickly. These objectives are not easily applied in ad hoc networks because most ad hoc MAC protocols rely on temporally random access techniques. As a result, we created a new MAC protocol called Synchronous Collision Resolution (SCR). SCR assumes nodes are synchronized and thus can contend simultaneously. A collision resolution signaling mechanism resolves contentions. The predictability of SCR simplifies the implementation of energy conservation mechanisms. Additionally, SCR orchestrates spatial reuse of spectrum, enables the effective use of multiple channels, arbitrates access based on priority and enables reservations for streaming.
