In Wireless Mesh Networks (WMNs), many applications are based on broadcast, such as the public security information, weather forecast and live show for users. Besides, broadcast is also a fundamental component of network protocols. Many broadcast approaches has been proposed like flooding and node-based CDS(N-CDS) scheme, but few have promising performance when used in multi-channel scenarios. In...
Network coding has been proven to be an effective technique to increase the throughput and enhance robustness of various wireless networks including tactical heterogeneous wireless networks. Usually, the tactical heterogeneous wireless networks consist of different wireless links including high bandwidth links like IEEE 802.11 and low bandwidth links like UHF and VHF. Load balancing is an effective...
Anypath routing can improve the end-to-end throughput by exploiting the broadcast nature of wireless communication media in wireless networks. Although anypath routing has been extensively studied in recent years, the problem of anypath routing in wireless networks with directional antennas has not been fully investigated. To the best of our knowledge, we are the first to study the joint problem of...
In the past few decades, wireless networks based on different standards have been developed quickly, and the coexistence of multiple communication systems has turned into reality. Due to the need for mobile computing or pervasive computing, quick and accurate protocol identification and analysis technology is required. Rather than employing the traditional demodulation-based method that requires to...
WANETs (Wide-Area wireless NETworks) is a recent network architecture where the nodes are spread out all over the world but behave exactly as if they are part of a single-hop or multi-hop wireless network at the PHY and MAC layers. At the same time, IEEE 802.11 devices are popular all over the world. When IEEE 802.11 meets with WANETs, the transparent Software Defined Access Points (SoDA) in WANETs...
WANETs is a recent network architecture where the nodes are spread all over the world but behave exactly as if they are part of a single-hop or multi-hop wireless networks at the PHY and MAC layers. Without distinguishing data packets and noise, the Software Defined Access Point (SoDA) samples the wireless channel for the uplink and multicasts the sampled data via Internet to other SoDAs. This leads...
We study the scaling capacity of wireless sensor networks in case of multiple gateways are presented. In such a heterogeneous network, many gateways are needed to gather data from the sensor nodes in network. Different from the previously studied single-gateway model, our proposed gateway access model allows multiple gateway nodes being seamlessly connected with high speed wire-line or wide-band radios...
