<strong>Performance Analysis </strong> The metrics are used to assess the performance of the proposed method in the simulations: download cost, download time and packet redundancy or useful information transmission subject to realistic constraints regarding peer's demand, capacity and dynamicity. 1. <strong>Download cost:</strong> This metric refers to the effort of the client need to spend in the system to download the needed data. 2. <strong>Download time:</strong> This metric refers to the time needed for the client to download the entire content. 3. <strong>Packet redundancy:</strong> This metric is referred to transmit and obtain useful information to and from other peers in the network. 4. <strong>Failure rate:</strong> It is defined as the number of peers is not able to complete the downloading of entire content due to missing of some blocks in the network. <strong>Link Stress:</strong> It is the ratio between the number of packets sent over a link and the number of useful packets to maximum nodes transmitted over the link. For example, a stress of 4 respects to case where each packet is transmitted four times over a link. Effective utilization of available bandwidth is evaluated for peers to exchange the content.
