Peer-to-Peer networks attracted a significant amount of interest because of their capacity for resource sharing and content distribution. Content distribution applications allow personal computers to function in a coordinated manner as a distributed storage medium by contributing, searching, and obtaining digital content. Searching in unstructured P2P networks is an important problem, which has received considerable research attention. Acceptable searching techniques must provide large coverage rate, low traffic load, and optimum latency. This paper reviews flooding-based search techniques in unstructured P2P networks. It then analytically compares their coverage rate, and traffic overloads. Our simulation experiments have validated analytical results.

“…Researches show that P2P protocols in wireless networks might not perform as well as they do in wired networks (Oliveira et al, 2005). A protocol using epidemic flooding to locate objects outperforms Chord in terms of query response rate, which is one of the key performance metrics.…”

Efficient content distribution is one of the emerging applications in vehicular networks. To provide scalable content distribution in vehicular networks, Chord peer-to-peer overlay could be applied. Most P2P protocols, including Chord, are designed for wired-line network, and might perform poorly in mobile networks. Mobile Chord (MChord) is proposed to enhance the P2P performance over vehicular ad hoc network (VANET). In addition, cross-layer design to improve MChord performance in VANET is also investigated. Extensive NS-2 simulations with vehicular mobility traces are conducted to evaluate the P2P overlay performance in VANET. Mobile Chord and its cross-layer design outperforms the original Chord in various aspects, including application layer forwarding steps, query response ratio, correct query response ratio, and application delay.

“…In this case study we implemented a self-configuration management module for unstructured peer-to-peer (P2P) networks, since our previous work [23] showed that such networks perform better than structured ones on MANETs. Unstructured networks can be divided into flooding-based and random walk-based.…”

“…Random walks use four walkers with a TTL equal to 25% of the number of nodes. For Flooding, the TTL was set to four, following the results in [23]. The FLOOD_THRESHOLD_EVT and RW_THRESHOLD_EVT events are triggered when the occupation is below 10% and over 50%, respectively.…”

Abstract. Due to the emergence of multimedia context-rich applications and services over wireless networks, networking protocols and services are becoming more and more integrated, thus relying on context and application information to operate. Further, wireless protocols and services have employed information from several network layers and the environment, breaking the layering paradigm. In order to cope with this increasing reliance on knowledge, we propose MANKOP, a middleware for MANETs that instantiates a new networking plane. The Knowledge Plane (KP) is a distributed entity that stores and disseminates information concerning the network, its services and the environment, orchestrating the collaboration among cross-layer protocols, autonomic management solutions and context-aware services. We use MANKOP to support the autonomic reconfiguration of a P2P network over MANETs. Simulation results show that the MANKOP-enabled solution is applicable to more scenarios than the classic approaches, as the network adapts its query dissemination strategy to match the current conditions of the peers.
