Peer-to-Peer Multimedia Distribution on Radio Channel and Asymmetric Channel

This chapter is organized as follows, the scenario and the main hypotheses of the chapter are explained in section 2. Section 3 describes the peer-to-peer algorithms used to build the peer-to-peer distribution networks. In section 4 we present how is estimated the maximum delay of a peer-to-peer distribution network. In this section we present the theoretical optimum in which it is maximized the average maximum number of peers and it is minimized the average maximum delay of the peer-to-peer distribution network. Moreover the simulation results for the asymmetric channel are reported in the last part of this section. In section 5 we analyse the behaviour of the peer-to-peer algorithms in a simple radio channel. In this section we present: the radio channel characterization; the model used to establish the bit error probability of each peer of a peer-to-peer distribution network; the peer-to-peer network simulator used to simulate the behaviour of the radio channel in the peer-to-peer distribution network; the validation of the model of the peer-to-peer network in an unreliable environment (radio channel) through the simulation results; the results used to establish which peer-to-peer algorithm builds the best peer-to-peer distribution network in an unreliable environment.
