Abstract
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.
