Efficient Protocols for Wireless Power Transfers in Ad Hoc Networks 537
where dist
i
is the distance of node i from the mobile charger, with the minimum taken over all nodes
in the network (or at least a large part of it). In other words, this protocol prioritizes nodes with high
criticality and small distance to the mobile charger. Since this protocol requires a global knowledge
of the state of the network, it is expected to outperform all other strategies that use only local or limited
network information, thus somehow representing an online centralized performance upper bound.
However, it would not be suitable for large-scale networks as it introduces ...
