A Connected Dominating Set (CDS) is a subset V′ of V for the graph G(V, E) and induces a connected sub graph, such that each node in V - V′ is at least adjacent to one node in V′. CDSs have been proposed to formulate virtual backbones in wireless ad-hoc sensor networks to design routing protocols for alleviating the serious broadcast storms problem. It...
A Connected Dominating Set (CDS) performs a vital role in wireless ad-hoc sensor networks, which can establish a virtual backbone and thus leads to less maintenance overhead and information exchanges in wireless communications. In this paper, our algorithm first finds a prior CDS and then uses the Minimum-Weight Spanning Tree (MST) to optimize the result. Our algorithm applies effective degree, the...

A connected dominating set (CDS) performs a vital role in wireless ad-hoc sensor networks, which can establish virtual backbones and thus leads to less maintenance overhead and information exchanges in wireless communications. In the literature, many distributed algorithms applied in wireless ad-hoc sensor networks have been proposed. However, we find many of these algorithms are divided into different...
Communication networks play a critical role in smart grid, as the intelligence of smart grid is built based on information exchange across the power grid. In power transmission segments of smart grid, wired communications are usually adopted to ensure robustness of the backbone power network. In contrast, for a power distribution grid, wireless communications provide many benefits such as low cost...
The emerging Wireless Mesh Networks (WMN) is a broadband access technology with the properties of multi-hop and self-organization, which has advantages of easy deployment, self-recovering, low cost and high scalability. The paper firstly introduces related works of wireless mesh networks; then describes the deployment of a real indoor testbed SJTU-MESH architecture and click based implementation including...
Efficient implementation of FIR (finite-impulse-response) equalizers for wireless channels has attracted much attention these days as equalizations can improve the link performance in hostile mobile radio environment by compensating for inter-symbol interference created by multipath within time dispersive channels. Meanwhile, the MIMO (multiple-input-multiple-output) technique becomes a trend in wireless...
Wireless Mesh Network (WMN) is an emerging technology that has developed a lot these years. WMN has the feather of self-organization, distributed structure. The main topological characteristic of WMN is that there are only one or several node connecting to the infrastructure network as gateway and all other nodes connect to the gateway through the relay of the neighboring nodes, and then connect with...
Much work has been done to modify the TCP protocol to improve TCP performance - mainly throughput, over wireless link. However, such improvements need to change the TCP implementation on user systems, which is usually difficult to deploy. In this paper, we investigate the effectiveness of enhancing the TCP performance over wireless link by tuning the packet scheduling schemes. Based on an opportunistic...
