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...
Two-hop relay algorithm serves as a class of promising routing protocols for mobile ad hoc networks (MANETs). This paper proposes a general two-hop relay algorithm with combination of both packet redundancy and erasure coding techniques, and focuses on the delay performance there. Our new algorithm is abbreviated as 2HR-(f, x), where f is the packet redundancy limit and x is an erasure coding parameter...
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...
The combination of deflection routing and burst retransmission is an attractive scheme for resolving the burst contention problem in Optical Burst Switching (OBS) networks. Most of previous works on hybrid schemes use simulation approach to prove the efficicency. In this paper, we develop an analytical model for obtaining the overall burst loss ratio of an OBS network that take into account deflection...
