Messsage Spreading Estimating Methods in Ubiquitous Networks

According to the storing-carrying-forwarding method in the ubiquitous network, the status on the packet transmitting has the relationship with the spreading degree of messages, and the distributed estimating results can make the assistance on the designing on the routing and cache management mechanism. A novel method to estimate spreading degree of message is proposed in our paper. First, we estimate the copies number of each message according to delivery mechanism in ubiquitous networks, and then the copies number of each message are mapped into spreading degree of messages using non-uniform quantization methods. Simulations show the proposed estimating method is accurate, and the scalability can be guaranteed.
