Kunz: Energy-Efficient MANET Routing: Ideal vs. Realistic
Performance
Motivation
,Wireless
nodes are severely energy-constrained
–Typically
operated using a battery of finite capacity
–Limited
to no opportunity for energy scavenging
,Nodes
in multihop wireless networks cooperate by routing packets
–Lots
of research interest/proposed protocols, some standards approved by IETF (AODV,
DSR, TBRPF, OLSR)
–Routing
metrics: shortest hop (best effort), QoS routing (max throughput, min delay),
load balanced routing, energy-efficient
routing
,Sources
of energy consumption
–Radio
consumes bulk of energy (more than say CPU or disk)
–Radio:
Transmit > Receive > Idle >> Sleep
