All communication between nodes in each cluster occurs during intra-cluster communication, e.g., data transmission, exchanging the ACL, joining the cluster, and leaving the cluster.
It minimizes routing loads and enhances expandability of network by allowing participating nodes to authenticate each other without being interrupted by joining the cluster.
For the cluster members, if it finds more than one ancestor in the cluster head list, the principle can be simply implemented by joining the cluster with the greatest depth.
Four-year old Huddle recently moved in the Silicon Roundabout area of London, joining the cluster of other startups in the area which the UK government is promoting as a 'Tech City' area.
Here the motivating factors for joining the Cluster – resource sharing, training opportunities and networking were actualised.
In addition to fundraising, a number of cluster members identified opportunities for resource generation, training and capacity building as reasons for joining the cluster: Incentives to club together?
Interestingly, it seems that although self interest was an important factor for joining the cluster, in the second year of focus groups and Participant Observation, self interest was less predominant.
In this protocol, the cluster heads are probabilistically selected based on their residual energy and the sensor nodes join the clusters according to their power level.
Additional participants will join the clusters formed by the participants from RPAH based on the date they are recruited.
If a sensor node which receives many re-clustering messages belongs to ch c, it will need to choose a new cluster head whose re-clustering message has the strongest signal to join the cluster.
