Cross-layer design of P2P file sharing over mobile ad hoc networks

Abstract

Peer-to-peer file sharing over mobile ad hoc networks (MANET) has become a popular application due to the rapid growing number of mobile devices. However, the fact that mobile nodes in a MANET dynamically alter their locations and join/leave the P2P system has posted many challenges in designing a robust and scalable P2P system. Although, in the literature, flooding-based P2P approach has been shown to be robust in a highly dynamic network, it leads to poor efficiency in terms of bandwidth usage and scalability. A new design is required in which cross-layer designs and cognitive approaches could be applied such that it could interact with the requests of users and respond to dynamic change of network topology. In this paper, we propose an efficient and scalable P2P file sharing system over MANET based on Swarm Intelligence, referred to as P2PSI. By applying the cognitive behaviour of the real ant colonies, P2PSI owns the capability of adaptive learning of routing path and is able to cope with mobility problem without flooding. Moreover, P2PSI also adopts cross-layer design to reduce the redundant message overhead and query latency. Performance of P2PSI is evaluated and compared to two existing cross-layer design service discovery protocols through simulations. Our simulation results show that P2PSI achieves better performance in terms of control overhead and request success ratio.

Structured Peer-to-Peer overlay deployment on MANET: A survey

“…If the used P2P overlay is the base for categorisation, at the most basic level approaches which use unstructured and structured overlays can be distinguished [47]. As this paper focusses on approaches employing structured overlays, such approaches can be further divided into subcategories according to the hop-count performance of the overlay algorithm (one-hop, multi-hop, variable hop).…”

An Efficient Overlay for Unstructured P2P File Sharing over MANET using Underlying Cluster-based Routing

“…Flooding a packet in the network using flat routing is inefficient and does not scale well [25]. In [10], using swarm-intelligence, the authors proposed a solution, called P2PSI, for addressing free-riding and hot-spot problem of unstructured P2P file sharing over MANETs. They divided the files into different categories and a pheromone-table was built up on each node which had routing information for each category of files instead of an individual file.…”

An improved virtualization layer to support distribution of multimedia contents in pervasive social applications

“…1: plain AODV, VNAODV on top of the VNLayer, VNAODV þ on top of the VNLayer þ, OLSR (Clausen et al, 2003) and ARA (Guenes et al, 2002). AODV, OLSR and ARA are the most representative examples of routing algorithms used for P2P distribution of contents in MANETs, along with DSDV (Perkins and Bhagwat, 1994) (an antecedent of OLSR) and Bee (Wedde and Farooq, 2005) (conceptually similar to ARA) (Gurumurthy, 2009;Tang et al, 2005;Sbai et al, 2010;Hwang and Hoh, 2009;Dhurandher et al, 2009;Castro et al, 2010;Barbeau, 2012;Wang et al, 2014).…”
