Energy Efficient Interest Forwarding in NDN-Based Wireless Sensor Networks

Algorithm 2

Least cost Interest forwarding at node .

Input: entries for the same content prefix in the FIB; the hop and the

energy metrics of the entry are denoted as and ;

() Calculate the aggregated metric for each entry;

     , 

() The ForwarderID of the entry with the least aggregated metric is

chosen as the neighbor forwarder:
