“…Video is less sensitive than voice. According to VoIP standards packet loss greater than 1% is likely to compromise the whole session, leading to several audio drop-outs [2]. This inevitably draws the conclusion that in the four-hop routing of Scenario 2 users might experience problems, since packet loss percentage rises to 1.03% after less than 120 sec of established audiovisual communication.…”

This paper describes the design and prototype implementation of a communication platform aiming to provide voice and video communication in a distributed networking environment. Performance considerations and network characteristics have also been taken into account in order to provide the set of properties dictated by the sensitive nature and the real-time characteristics of the targeted application scenarios. The proposed system has been evaluated both by experimental means as well as subjective tests taken by an extensive number of users. The results show that the proposed platform operates seamlessly in two hops, while in the four hops scenario, audio and video are delivered with marginal distortion. The conducted survey indicates that the user experience in terms of Quality of Service has obtained higher scores in the scenario with the two hops.

“…An additional issue in the overall idea of this network architecture is peer cooperation. As shown in [2], most topology control algorithms assume that peers are cooperative, which is simply not the case. Peers are always trying to minimize their own costs such as the number of necessary communication links or the distance to other peers.…”

a b s t r a c t P2P overlay networks have attracted significant research interest due to their utility as virtualized abstractions of complex network infrastructures, optimized to satisfy specific criteria, e.g. minimum delay or shortest diameter. In the context of modern pervasive environments, which are characterized by complexity, heterogeneity, dynamicity, and mobility in terms of the underlying networks, the utilization of P2P overlays accordingly offers a series of advantages by countering the aforementioned adverse characteristics. The widespread deployment of pervasive environments and the plethora of proposed P2P systems, both call for a systematic way to study related research works. In this paper we review related research on P2P (peer-to-peer) overlay networks in pervasive environments. In this respect, we therefore analyze relevant requirements and discuss the application and deployment of P2P overlays and systems on top of the networking infrastructures that are supported by pervasive environments. Aspects such as scalability, resource discovery, algorithmic complexity, security, and support for dynamicity are examined for existing research works, in an effort to identify the most suitable P2P overlay for the requirements set by the nature of pervasive environments. We also taxonomize P2P overlays using the well-established classification scheme in regard to their structure or lack of it. Furthermore, we study the notions of multi-layer and bio-inspired P2P overlays that have great synergies with pervasive environments due to their inherent characteristics, especially in terms of flexibility and robustness. By describing and critically analyzing existing systems and discussing current research and open issues, we aim to instigate further research in this domain, while at the same time this work should serve as a point of reference for state-of-the-art P2P overlays in pervasive environments.

“…In [9] the author never consider the underlying layer locality to select the peer. Building on the observation that well matching overlay and underlay structures in MANETs imply less physical layer hops corresponding to virtual overlay hops, Mawji et al [10] introduce a topology control algorithm to reduce energy consumption and response times. In [11] node connects to neighbors based on two heuristics, namely the remaining energy levels of peers and the physical layer distance to other peers.…”

“…The main disadvantage of ORION is that network traffic may be increased rapidly when there are many peers within the communication range and a very large number of different files are distributed throughout the network. Recently, another approach to reduce energy consumption of peer-to-peer overlays built on top of mobile ad hoc networks and based on the theory of topology control has been proposed [10]. Improvements to this work included the introduction of peer mobility as an additional super-peer selection heuristic, as well as the modification of the IEEE 802.11 power saving mode in conjunction with the aforementioned two-layer p2p system to further decrease energy consumption.…”

Peer to peer (p2p) file sharing protocol and ad hoc wireless routing protocol shares many intriguing similarities even though they operate on a totally different level of a network. With the popularity of p2p application for resource sharing and the availability of resources has motivated the researchers to examine the potentials of p2p applications in a dynamic environment. With the success of p2p for file sharing applications, its benefits can be brought by constructing the overlay network with easy access of content to improve their availability and performance. This paper is one such an attempt to exploit the potential of mobile characteristics for the benefit of p2p application to satisfy the users demand. This paper focuses on how reliable content sharing could be realized in an ad hoc environment through peer to peer (p2p) system. This efficient content delivering system reduces the search latency of content peer selection. Also the reliable path for sharing content with trust calculation has been proposed. Unstructured peer to peer network is considered for the platform, emphasizing the content based interaction with a pro-active routing protocol at the network layer. The experiments have been performed on the network simulator NS-2 and the results showed that the proposed system improves the hit ratio and reduces the overhead traffic.
