We propose a novel successive relaying scheme based on network coding (SRS), which achieves the same spectral efficiency in half-duplex multi-hop relaying channels as point-to- point transmission does. Except for the source and destination nodes, every hop in the multi-hop relaying link, two relay nodes are arranged, a transmitting relay node and a receiving relay node, and continuously switch their...
Indoor positioning system that make use of received signal strength and existing wireless local area network infrastructure have recently been the focus for supporting location-based services. This paper presents a new indoor location tracking algorithm, that use:(1)signal strength probability distribution estimated by histogram method, addressing the noisy wireless channel, and (2)particle filter...
In multi-hop wireless networks, network coding can take advantage of the bi-directional traffic flows to increase the achievable throughput. To combat fading in wireless channel, cooperative diversity is integrated into the network-coding schemes. In this paper, we propose an opportunistic cooperative network-coding scheme based on space-time coding (OCNC), which combats channel fading and improves...
Broadcast is a method that allows the nodes in the multi-hop wireless networks share the data efficiently among other nodes. Because the transmissions of broadcast packets are related to send or receive of multi-nodes, it is difficult to ensure the reliable transmission of broadcast packets. In this paper, a new single channel synchronous MAC protocol, termed the three-handshake broadcast protocol...
