Cluster members send back energy amount. Round 3 – 5 Head chooses new cluster head Head informs cluster members and parent and children on backbone tree of new head, then changes status to cluster member Cluster members, parent and children update new head Reconfiguration of CHNetArch Node Move-in A – Join as cluster member Round 1 - 2 New node broadcasts a message to join at range d/4 and receives replies Round 3 New node chooses a cluster head with strongest signal and becomes cluster member B – Join as cluster head Round 3 – 5 New node broadcasts a message to join at range d and receive replies New node chooses a parent (cluster head with weakest signal) Node Move-out A – Leaving node is cluster member Rounds 1 – 2 Cluster member sends message to cluster head and receives reply, then leaves network B – Leaving node is cluster head Rounds 1 - 7 Cluster head invokes head rotation then follows steps to leave network as cluster member Detailed Design and Implementation – Robust Networking Architecture (CHNetArch)
