Dynamic Parameter Selection in Packet Radio Transmissions
Nachum Shacham · 1986
The special characteristics of multi-hop packet radio networks result in dynamic channel behavior and time-varying network topology whih cause variations in the signal-to-noise ratio of received packets and in the congestion levels. Transmission parameters such as power, bit rate, code rate, and inter-transmission time can be used to stabilize the network characteristics as seen by high level protocols and to enhance the network performance. Adaptive protocols that control these parameters are described and their effects on the network performance and their interactions are discussed.
