That is because even though more neighbors of each node might shorten the shortest paths from the sink nodes to the source node, they also reduce the chance for different sink nodes to share the same ... with PST decrease slightly as the node density increases. This is be- cause when there are more sensor nodes, each node may have more neighbors, which help to further shorten the short- est...

... particular they proved that for x>0andα = 0 the function [Γ(1 + 1/x)] x decreases with x, while when α =1 the function x[Γ(1 + 1/x)] x increases. Moreover they also showed that the values α = ... we state that this is always true in general, more pre- ciously we state the following conjecture: for any p>1, there exists a right neighbour- hood of (9(3p +1)/4(2p +1)) 1/p such that E(x...
