The development of a robust, autonomous sensor network platform for environmental monitoring.
This paper describes an approach to the approaches being explored for a Sensor Network platform being developed for the DTI/NextWave technologies programme. The approach being adopted is to develop the system as a community of devices which use self-organising techniques to provide key functions. The devices are, largely, based on commodity technologies, thus providing a low cost basis. We give an outline of the approach and project and illustrate the techniques being developed with specific functions for: control, management, data retrieval and data quality control. The target application is off shore sea shelf monitoring; but the techniques being developed may be applied to a range of problems
Self-Organising Pattern Formation: Fruit Flies and Cell Phones
. The bristles of the fruit fly, Drosophila, form part of the peripheral nervous system of the animal. The pattern of these bristles in the adult is produced by self-organisation of cell types during embryonic and larval development. The mechanism of bristle differentiation has been the inspiration for the optimisation algorithm presented here. The algorithm is used to produce a dynamic channel plan for a cell phone network. Radio channels are a scarce resource and minimising interference is a significant problem for mobile network operators. 1. Introduction 1.1 Growing A Channel Allocation Plan The purpose of the work presented here is to show how the mechanisms of bristle differentiation in the fruit fly can be used as an inspiration for an online dynamic channel allocation algorithm. The self-organising nature of the fruit fly developmental process is preserved and with it the advantages of robustness and flexibility. The mechanisms used so effectively by nature to ensure that two..
