Abstract
Official abstract text for this publication.
In one embodiment, hidden neighbor relationships are identified based on received neighbor information from a plurality of nodes in a communication network. Based on determining a number of hidden neighbors for a particular node at various node parameters, a cost function associated with the particular node may be determined and utilized. In another embodiment, a number of hidden nodes of the particular node is determined across a range of transmission powers, and a delay associated with the particular node reaching a root node in the network across the range of transmission powers is also determined based on the neighbor nodes reachable at respective transmission powers. A tradeoff is determined across the range of transmission powers between the number of hidden nodes and the delay, and then the transmission power of the particular node can be set based on an acceptable determined tradeoff.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: receiving neighbor information from a plurality of nodes in a communication network; identifying hidden neighbor relationships within the communication network based on the neighbor information; determining a number of hidden neighbors for a particular node of the plurality of nodes at various node parameters, wherein a hidden neighbor is hidden from the particular node due to the hidden neighbor being out of communication range wit…
