MPR Selection
n OLSR_R1: similar to OLSR (i.e., choose 1-hop
neighbours that cover maximum number of 2-hop
neighbours), tie-breaker now maximum bandwidth
n OLSR_R2: select the best bandwidth neighbors as
MPRs until all the 2-hop neighbors are covered.
n OLSR_R3: selects the MPRs in a way such that all
the 2-hop neighbors have the maximum bottleneck
bandwidth path through the MPRs to the current
node
