Choice of Router Priority Each router can select its Router Priority dynamically, e.g., using the following criteria: The Bandwidth capacity of node: higher priority for higher bandwidth Neighbor stability (average lifetime of neighbors): selecting nodes with stable neighbors will increase the lifetime of adjacencies. Node degree: higher priority for larger degree reduces number of DRs for small networks, but not for large networks (see simulation results). Makes CDS less stable since node degree changes. Willingness to be a relay (e.g., due to battery life). A router that has been a DR or BDR for a certain amount of time can reduce its Router Priority, so that the burden of being a DR/BDR can be shared among all routers. |
