This paper supposes a new graph model for wireless Mesh Networks (WMN) with MIMO channels. The model is based on the anttena model and single channel mesh, place edges into different channel plane avoiding interference. The active edge group algorithm select the most active edges without interference, then perform high throughput. The coding scheme in the(More)
Routing and scheduling act important roles in improving capacity and throughput in wireless mesh networks. In this paper, Cayley graph model is suggested for wireless Mesh Networks (WMN) with MIMO channels for efficient routing and fair scheduling. The model is based on the multiple interfaces, directional antennas, single channel mesh model. And the link(More)
The IEEE 802.16 standard provides a scheme for creating multi-hop relay networks, which can be deployed as a high speed wide area wireless network at low cost. Although the standard defines signaling mechanisms in mesh mode, however, it doesn’t specify wireless resource management in the protocol. In this paper, we address the problem of resource allocation(More)
Multiple sequence alignment is a fundamental problem in computational molecular biology. This paper shows a brand new refinement strategy combining divide-and-conquer and Beam-Through alignment (DC-BTA). Optimization objective function (OF) is additively computed with new stage beam area, which is corresponding to beam area rate in [6]. The refinement is(More)
Multiple sequence alignment is a fundamental computing research topic in bioinformatics field. This paper introduces the implementation of BTA multiple sequence alignment and discusses divide and conquer cut points strategy for long biology sequences. The BTA alignment software can provide unique cut point strategy and can recursively refine the alignment.(More)
Multiple-radio multiple-channel (MRMC) wireless mesh networks (WMNs) generally serve as wireless backbones for ubiquitous Internet access. These networks often face a challenge to satisfy multiple user traffic requests simultaneously between different source-destination pairs with different data transfer requirements. We construct analytical network models(More)
