In this work, a novel bio-inspired data dissemination mechanism is presented. The mechanism, called service-oriented forwarding, is enhanced to allow it to gather and process situational service knowledge on other nodes in the network for the purpose of enabling smart and scalable message forwarding in the dynamic network environments of the future. All the required processing is done at the network level by the mechanism and it operates in a distributed and self-organised manner, requiring no global or external control. The behaviour and performance of the proposed mechanism are evaluated by means of simulations. The main functionalities of the mechanism are implemented as an additional module for a simulation environment and then compared to another bio-inspired message dissemination protocol. The main performance metrics considered here are the ability to successfully deliver service messages to pertinent nodes in randomly generated network topologies and the total network load imposed by disseminating data and control messages. Based on the results obtained in the simulations, it is concluded that the network mechanism presented here does have the potential to enhance the efficiency of message dissemination by collecting information on the service interests of the network nodes in a bio-inspired manner. Several promising items to further improve the performance of the mechanism in the future are also identified.
