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...
Location-based services (LBS) are an integral part of the mobile ecosystem today, relying on the Global Positioning System (GPS) and other technologies. However, while these technologies have been highly successful at positioning outdoors, they either fail to obtain a fix or do not provide the necessary accuracy indoors. In this paper, we will describe a low-cost high-accuracy indoor positioning system...
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...
