Delay Tolerant Networks (DTNs) are intermittently connected mobile networks, in which a fully connected path from source to destination does not exist. Therefore in these networks, message delivery relies on opportunistic routing where nodes use store-carry-and-forward paradigm to route the messages. However, effective forwarding based on a limited knowledge of contact behavior of nodes is challenging...
In urban vehicular network, existing routing protocols using beacon message scheme and P2P (peer to peer) density discovery scheme can hardly make a good performance as well as keep a high feasibility. This paper proposes an IGOR (improved geography and overlay routing) in urban vehicular environment. In IGOR, RSUs (road side units) are introduced to support the road density discovery. A passive neighbor...
Mobile ad hoc network and peer-to-peer networks are most advancing and emerging research areas in the recent years. Both of these networks are based on the same phenomenon like self-configuration and self-organization. Although, peer-to-peer network was firstly designed for wired network but now a days it may be deployed over mobile ad hoc network. When P2P networks are deployed over ad hoc network,...
The work presents a decentralized protocol that allows self-organization of autonomous wireless devices in mobile mesh networks. In the resulting infrastructure the routing and information services are provided in a peer-to- peer fashion. Both services are performed through multi- hop radio transmissions among participant nodes with no fixed infrastructure required and avoiding to use broadcast of...
A mobile ad-hoc network (MANET) is a peer-to-peer wireless network where nodes can communicate with each other without the use of infrastructure such as access points or base stations. Nodes can join and leave the network at anytime and are free to move randomly and organize themselves arbitrarily. Due to this nature of MANET, it is possible that there could be some malicious and selfish nodes that...
A mobile ad hoc network (MANET) is composed of a set of wireless mobile devices that are able to communicate with each other in a peer-to-peer mode. In recent years video streaming over MANETs has drawn significant attention due to the popularity of high-speed IEEE 802.11 standard series. However, it is still a challenging task for channel variation and bandwidth limitation and fluctuation. In this...
Peer to Peer (P2P) as well as mobile ad hoc networks (MANETs) follows the same idea of creating a network without the help of central entities. Both networks are faced with the same fundamental challenge - routing. Distributed Hash Tables (DHTs) have recently proven to be a novel and efficient way for locating objects. Routing protocols of MANETs can potentially benefit from the combination with DHTs...
Peer-to-peer (P2P) networks and mobile ad-hoc networks (MANET) share many similarities. However, building a P2P overlay network directly on top of a MANET can lead to poor performance unless specific cross-layer optimization is adopted. We propose a novel solution comprised of a MANET routing protocol, a middleware and an inter-layer communication mechanism which facilitates P2P application development...
This paper proposes a method of improving the efficiency of P2P(peer-to-peer) content sharing services like BitTorrent using the network information in the mobile ad hoc network (MANET) environment. While many papers focus on P2P information dissemination and searching in the MANET environment, this paper focuses on the P2P data delivery strategy. This strategy involves peer selection and piece selection...
Incentive models are becoming increasingly popular in mobile peer to peer networks (M-P2P) as these models entice node participation in return for a virtual currency to combat free riding and to effectively manage constraint resources in the network. Many routing protocols proposed are based on best effort data traffic policy, such as the shortest route selection (hop minimization). Using virtual...
Mobile Ad hoc NETworks (MANET) and Peer-To-Peer (P2P) systems are emerging technologies sharing a common underlying decentralized networking paradigm. However, the related research activities have been mainly developed by different research communities, nullifying therefore the idea of an unitary approach able to assure effectiveness integrated solutions. In this paper, we propose a DHT-based routing...
An ad hoc network is a peer-to-peer network without no centralised server. Mobile ad hoc network(MANETs) is a promising new wireless communications paradigm in which network device may move around and end hosts may function as a router. It is a key of success of being deployed to properly address the security problems. Although many research focus on how to deliver packets from one node to another,...
Both Peer-To-Peer (P2P) and mobile ad-hoc networks (MANETs) aim to provide seamless connectivity and services in a dynamic and decentralised environment. These two technologies, if unified, may be able to realise MANETs as a viable commercial technology and will enable the development of widespread distributed applications for MANETs. The push towards wireless ubiquitous computing means that service...
The study of peer-to-peer network and mobile ad hoc network (MANET) are currently two hotspots in distributed computing and mobile communication researching domain. By building up a P2P overlay network on top of MANET's physical infrastructure, we effectively integrated P2P network's advantage on sustaining highly dynamic network into the design of MANET routing protocol. By deploying passive MANET...
