If old cluster head priority is higher than backup node, then old cluster head will become backup node and backup node will act as cluster member within the cluster; otherwise, old cluster head will act as cluster member and the status of backup node will remain the same.
Five of these clusters had a high LLR; the expert panel ranked all 5 of these clusters high priority and identified them as clusters of concern.
Specifically, to balance energy distribution among all clusters, merging priority should be given to the cluster pairwise with the least sensors.
In particular, Cluster Two and Three priorities currently have collaborative projects underway.
The group consensus was that this cluster's priorities were well-defined and feasible to fund in their current form.
After waiting up to delay time, high priority cluster head elected as cluster head and other changes its status to cluster member within the same cluster.
CSP i,s : cluster head selection priority of S i in sector s.
For this, each TCDC sensor node calculates its cluster head selection priority (CSP), separately for each communication sector, which is a function of the number of neighbor nodes in that sector, its own residual energy, and its distance from the sink node.
Then, each sensor node calculates cluster head selection priority (CSP) for itself and its neighbors following Eq. 2, begin{array}rcl@ text{CSP}_{i,s} &=& w_{1} times frac{E_{i}}{E_{0}} + w_{2} times frac{|n_{i,s}|}{N_{text{max}}^{i}} + w_{3} & times & left{1- frac{d(S_{i},text{SINK})}{d_{text{max}}}right}, quad forall s in Psi_{C} end{array} (2).
After the review, the group was directed to brainstorm, categorize and subsequently define thematic or "cluster" areas of priority for operations research.
