In environments where position information is not assumed, an efficient data access is a very challenging issue. Few years back, a new relative coordinate's concept was introduced in the Relative Coordinates Rumor Routing protocol (RCRR). RCRR speeds up the crossover between event-agents and query-agents in the network. However, when facing network scalability, it suffers from its non-optimal generated paths. Consequently, more consumed energy and delay are generated. The main contribution of this work consists on enhancing event and query-agents trajectories with the same energy cost needed when implementing the relative coordinates system in RCRR. We have conducted several simulation tests under different scenarios to compare and evaluate the proposed Optimized RCRR (ORCRR) protocol performances. Results show that ORCRR enhances the query delay up to 54.56 % and the consumed energy is reduced by 5.28 %.
