Abstract
Two major factors that limit the throughput inmulti-hop wireless networks are the unreliability of wirelesstransmissions and co-channel interference. One promising techniquethat combats lossy wireless transmissions is opportunisticrouting (OR). OR involves multiple forwarding candidates torelay packets by taking advantage of the broadcast nature andspacial diversity of the wireless medium. Furthermore, recentadvances in multi-radio multi-channel transmission technologyallows more concurrent transmissions in the network, and sh ....etc

Opportunistic Scheduling in Wireless Networks

Introduction
In wireless networks, the channel conditions are time-varying due to the fading and shadowing. Different wireless users experience different channel conditions at a given time. This gives raise to the multi-user diversity effect: when there are many users which fade ind ....etc

ABSTRACT
Opportunistic routing has recently attracted much attention as it is considered a promising direction for improving the performance of wireless ad hoc and sensor networks. With opportunistic routing, intermediate nodes collaborate on packet forwarding in a localized and consistent manner. Opportunistic routing greatly increases transmission reliability and network throughput by taking advantage of the broadcast nature of the wireless medium. In this article we first illustrate the basic idea behind opportunistic routing, and then cate ....etc

hello,
I am a final year student. i need help in my project. can anyone post the java or .NET code that demonstrates the comparison of any three of the opportunistic routing protocol such as Ex-OR, MORE, GeRaF, CORE, HARBINGER, OAPF. thanks in advance. ....etc

Abstract
Opportunistic networks are wireless mobile networks in which a continuous end-to-end path between a source and a destination is not necessary. Messages are stored at intermediate nodes, and opportunistically forwarded when a more suitable next hop towards the destination becomes available. A very interesting aspect understands how usersâ„¢ mobility patterns impact on the performance of routing protocols. Starting from this motivation, in this paper we take into consideration group mobility models, whose movement ....etc

Abstract

Opportunistic networks are one of the most interesting evolutions of MANETs. In opportunistic networks, mobile nodes are enabled to communicate with each other even if a route connecting them never exists. Furthermore, nodes are not supposed to possess or acquire any knowledge about the network topology, which is instead necessary in traditional MANET routing protocols. Routes are built dynamically, while messages are en route between the sender and the destination(s), and any possible node can opportunistically be used as ....etc
