If a tree T is composed of a root node
x with A and B as respectively left and right subtrees, we write T = x(A, B).
It has been proven in the literature  that the transmission range per node has to be at least twice the sensing range of the nodes to ensure that coverage implies connectivity, (iii) A data gathering tree is obtained by conducting a Breadth First Search (BFS)  of the spanning tree, starting from a root node
that serves as the leader node for the tree, (iv) The leader node of a data gathering tree remains the same until the tree exists and is randomly chosen each time a new tree needs to be determined, (v) Data gathering proceeds in rounds.
Therefore, services execution cab be extracted as a single root node
, and the output is expressed as a single variable node.
The height of the tree is determined by the length starting from root node
down to the leaf node.
Firstly, the whole volume dataset is regarded as the root node
of octree, and the value is assigned to the member variables.
The minimum allowed number of entries in the root node
is 2, unless it is a leaf; Performance Analysis of Spatial Data Indexing
k]) is a directed acyclic graph G = (V,E) with one root node
and a set of terminal nodes, where:
A tree structured network is formed by assigning a mesh point as a root node
and other mesh points in the network proactively maintain paths to the root node
and distance vector routing tree will be created and maintained.
If there is a single centre, mark it as the root node
Evaluations are based on a 0-3 root node
scale with 0 being no damage and 3 a fully damaged root.
This network is composed of a single root node
that is responsible for the entire data set and a number of child nodes which each serve to correct the mistakes made by the network within a specific subset of the data.
The advantage of XPath over other search engines is that in XPath, expressions are resolved relative to the current node or to the root node
