Kunz: Energy-Efficient MANET Routing: Ideal vs. Realistic
Performance
Modifying OLSR to make it
Energy-Efficient
,Two (obvious)
choices for modifying OLSR routing decisions
MPR
Selection
Path
Determination
,Prior work:
change one or the other (or both) to achieve QoS routing, etc.
Typically:
best results are achieved when both components are modified
,Our changes: modify
both components as explained below, explore performance of all combinations
MPR Selection: pick 1-hop neighbors with max residual energy level until
all 2-hop neighbors are covered
(note: may not result in minimum set of MPRs)
Path determination: run Dijkstra, but assign weight to links based on
receiving nodes reciprocal
energy level (steers routes away from nodes with low energy level, avoids need
for threshold)
,Prior results: best
option is to only change Path Determination, second best often is to combine modified path determination with
modified MPR Selection
