Energy consumption is a main research issue inwireless sensor networks; and particularly in those where nodescollaborate to reach a goal. This article explores the energyconsumption in mobile devices participating in a human-basedwireless sensor network. Specifically, the paper proposes the useof a message predictor to help detect and reduce the number ofunnecessary control packets delivered by the nodes as a way tokeep updated the network topology. In order to evaluate thisproposal, the Optimized Link State Routing protocol wasmodified to add a message predictor between the routing and thenetwork layers. Eleven simulations were performed using aparticular setting. The preliminary results indicate the use of themessage predictor can help reduce considerably the nodes energyconsumption without affecting the routing capability of theprotocol. Although these results are still preliminary, they arehighly encouraging.
