Overlay construction for mobile peer-to-peer video broadcasting

Many two-layer hierarchy unstructured peer-to-peer (P2P) systems, comprising of superpeers and ordinary peers improved the performance of large scale P2P systems. The construction and maintenance of the superpeer overlay network play an important role in improving the performance P2P systems. One efficient method of constructing the superpeer overlay network is based on notion of Perfect Difference Networks(PDN).The construction and maintenance of network in this method is controlled by single bootstrap server. Such network is prone to single-point failures. The number of registration requests lost before getting up the failed bootstrap server and the delay in adding new peer to the network gets increased. The mechanism of maintaining and constructing the superpeer overlay network by making use of two bootstrap servers having slight different functionality proposed in this paper avoids single-point failures. It also ensures no loss of registration requests. The experimental results show that the delay in adding new peer to the network and number of registration requests lost are reduced.

Main Barrier

Video broadcasting is one of the efficient methods in implementing large-scale video-on-demand (VoD) systems. Managing large number of concurrent channels in a video server is the main barrier to implement Harmonic Broadcast (HB) in VoD applications. In this chapter, we propose a new transmission protocol denoted as Harmonic-Based Peer-to-Peer Broadcasting (HPB) to release the burden of HB by dispersing a large portion of workload over a number of clients denoted peer servers. As the bandwidth requirement of each segment in HB is different, we first develop a segment placement algorithm to balance the workload among peer servers. We then study the dynamic nature of peer-to-peer (P2P) paradigm on the design of the system. An analytical model is developed to determine the optimal number of peer servers required for the system under certain level of availability such that the workload of the central server can reach a target level. The results show that the workload of central server can be significantly reduced.

Overlay Construction

With the evolution of wireless technologies, mobile networks can provide much more interesting services and resources to users than before. Consequently storing, sharing and delivering resources efficiently have become popular topics in the field of mobile networks. Mobile Peer-to-Peer (the authors use mobile P2P for short hereinafter) networks, which are inspired by the great success of P2P networks, have been proposed to efficiently share the network resources among the peers in mobile networks. However, due to the characteristics of mobile networks and stringent constraints of applications, it is fairly difficult to construct mobile P2P networks. In this chapter, the authors present a survey of overlay construction in mobile P2P networks. First, they outline the design issues of running P2P networks on top of mobile networks. The authors then present a survey of existing overlay construction techniques for mobile P2P networks. They highlight the advantages and disadvantages of various overlay construction techniques for mobile P2P networks and further compare these methods. They also point out the open research issues in each sub-area and conclude with possible future research directions in mobile P2P overlay construction.
