This paper studies the performance of a general two-hop relay (2HR)- $(x,w,f) $ packet delivery scheme that combines both erasure coding and packet replication techniques in mobile ad hoc networks (MANETs). Under this packet delivery scheme, a group of $x$ packets is first encoded into $w(w\geq x) $ coded packets using erasure coding, and each coded packet is then replicated to at most $f$ distinct...
The two-hop relay algorithm with both the packet redundancy and erasure coding techniques serves as a promising routing algorithm to improve the packet delivery performance in mobile ad hoc networks (MANETs). This paper studies the packet delivery probability under this routing algorithm. We first develop a multi-dimensional Markov chain model to characterize the packet delivery process under the...
The lack of understanding on the fundamental performance limits is a major obstacle stunting the application of wireless ad hoc networks (WANETs). The upper bound on the packet propagation speed, an important component of the performance limits, has recently attracted a lot of academic interest. While the metric has been investigated for several network scenarios, two important aspects remain unexplored...
One major obstacle stunting the development and application of mobile ad hoc networks (MANETs) is the lack of a thorough understanding on the throughput capacity of these networks. Preliminary works regarding the exact capacity study of MANETs mainly focus on cell-partitioned networks, an oversimplified network model for practical MANETs. This paper studies the exact throughput capacity under a more...
In this study, we explore the effect of air gap between a glass based color conversion layer and a blue emitting chip on color rendering properties of a white light emitting diode by optical simulation method.
