Network Layer Capabilities

• Star and multihop topologies• Transparent recovery from power failure

and other transient conditions• Flexible routing scheme allows

application developers to minimize RAM requirements

• “Tunable” routing cost functions allow for various performance optimizations

• Supports low-power operation by allowing nodes – even routers – to sleep
