We develop and analyze low-complexity cooperative diversity protocols that combat fading
induced by multipath propagation in wireless networks. The underlying techniques exploit …

This paper describes ExOR, an integrated routing and MAC protocol that increases the
throughput of large unicast transfers in multi-hop wireless networks. ExOR chooses each …

End-to-end performance of two-hop wireless communication systems with nonregenerative
relays over flat Rayleigh-fading channels is presented. This is accomplished by deriving and …

This letter presents a study on the end-to-end performance of dual-hop wireless
communication systems equipped with nonregenerative fixed gain relays and operating …

This paper investigates the performance of practical physical-layer network coding (PNC)
schemes for two-way relay channels. We first consider a network consisting of two source …

We consider three-node wireless relay channels in a Rayleigh-fading environment.
Assuming transmitter channel state information (CSI), we study upper bounds and lower …

This paper describes Extremely Opportunistic Routing (ExOR), a new unicast routing
technique for multi-hop wireless networks. ExOR forwards each packet through a sequence …

In a distributed spatial diversity wireless system, not all antennas are located at one station
as in classical transmit diversity systems, but are dispersed at different, possibly mobile …

We develop two variants of an energy-efficient cooperative diversity protocol that combats
fading induced by multipath propagation in wireless networks, The underlying techniques …

This paper presents theoretical characterizations and analysis for the physical layer of
multihop wireless communications channels. Four channel models are considered and …
