The VST-TDMA access protocol has shown to have many advantages over existing protocols in centralized (star) wireless network architectures. As most data-link layer protocols, it does not have a recovery feature as data integrity is supervised by the connection-oriented transport protocols. Nevertheless, VST-TDMA possesses the flexibility to easily incorporate a retransmission feature that allows...
We focus on a new class of home networking applications that enable wireless communication between multimedia devices using the WiMedia MAC protocol. Applications like streaming video from DVD players to HDTVs, generate high data rates and can easily saturate the bandwidth even at the rates provided by UWB transmissions. Thus we need to enhance the MAC layer to improve bandwidth utilization and efficiently...
This paper presents a novel hierarchical and grid based reconfigurable optical-wireless network (GROW-Net) architecture. GROW-Net supports scalable and flexible integration of a large scale wireless mesh network in a municipal environment. Under the GROW-Net architecture, a joint evolution strategy is proposed to allow graceful upgrades in both optical backbone and wireless mesh network. To alleviate...
Due to lack of inexpensive infrastructure rural communities suffer from inadequate Internet access, which is gradually widening the digital division between town and countryside, resulting in degrading both social communication and business advancements. In order to examine the feasibility of constructing a community mesh network using partial off-the-shelf hardware and software components, our research...
A wireless network in which packets are broadcast to a group of receivers through use of a random access protocol is considered in this work. The relation to previous work on networks of interacting queues is discussed and subsequently, the stability and throughput regions of the system are analyzed and presented. A simple network of two source nodes and two destination nodes is considered first....
