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

Abstract
Ad hoc Networks are gaining popularity as a result of advances in smaller, more versatile and powerful mobile computing devices. The distinguishing feature of these networks is the universal mobility of all hosts. This requires re-engineering of basic network services including reliable multicast communication. This paper studies efficient routing mechanisms for multicast and broadcast in ad hoc wireless networks taking into consideration that, number of packet forwarding is the more important factor which has to be optimized than th ....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 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 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
