MAC-2: A MAC protocol for power control in mobile ad hoc networks.

摘要

Mobile ad hoc networks (MANETs) are multi-hop wireless networks where nodes cooperatively maintain network connectivity. These networks suffer from many problems, such as high power consumption, inefficient spatial reuse, and poor Quality of Service. These problems can be remedied by developing a medium access control (MAC) scheme which reduces power consumption by sending at the minimal power needed to reach the nodes involved in a connection, and which optimizes spatial reuse by allowing as many simultaneous exchanges as possible to occur in an area.; This thesis presents a comprehensive work that enhances the performance of MANETs through improvements at the MAC layer. This work is based on the IEEE 802.11a standard, which is not well suited yet for operation in MANETs. We propose a power efficient MAC layer protocol, with a physical layer extension, which makes the current IEEE 802.11a devices more suitable for operation in a MANET environment.
