The benefits of network coding on multicast in traditional multihop wireless networks have already been extensively demonstrated in previous works. However, most existing approaches cannot be directly applied to multihop cognitive radio networks (CRNs), given the unpredictable primary user occupancy on licensed channels. Specifically, due to the unpredictable occupancy, the channel’s available bandwidth...
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...
Wireless mesh networks (WMNs) are taking advantage of multiple radio interfaces to improve network performance, and numerous routing protocols have been proposed for WMNs. However, these routing protocols can not perform well in the heterogeneous multi-radio environment with distinct bandwidth difference, for little attention has been paid to routing overhead balancing. To address this issue, we present...
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 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...
Bandwidth of the subnets will influence the performance of heterogeneous ad hoc networks, in which various medium access control (MAC) protocols are adopted by various subnets. Jointly considering the bandwidth and MAC protocols of subnets can improve the performance of whole ad hoc networks. However, it is difficult for application to know what MAC protocols are adopted by the subnets on the path...
