plz explain me, i used eucledian distance to find minimum distance b/w nodes is it advantageous or not? or where we can use eucledian distance in sensor network

Consider this arrangement, in which node 3 needs to get data to node 2. The euclidean distance directly between node 3 and node 2 is shorter than going from 3 to 1 and then from 1 to 2, so algorithms based upon euclidean distance will assume that 3 must transit directly to 2. But the route between node 3 and node 2 is partly blocked, so the power costs to transmit from node 3 to node 2 might be higher than the cost of transmitting from 3 to 1 and then from 1 to 2.
