CONTROL SYSTEM AND METHOD FOR SELECTING A ROUTING SCHEME IN A COMMUNICATION NETWORK WITH LIFETIME-LIMITED NODES

摘要

The invention relates to method of evaluating a plurality of candidate routing schemes for a communication network and a control system for implementing the method. The communication network comprises a plurality of lifetime-limited nodes. The candidate routing schemes are evaluated against one or more lifetime-related or energy efficiency objectives in order to determine an optimal routing scheme that most closely approaches or meets the obj ective ( s ). The evaluation may be based on calculated lifetimes for nodes operating in the communication network according to each of the plurality of candidate routing schemes. The objective (s) may seek to optimise the energy consumption (i.e. transmission energy), and hence the lifetime, of the network.
