In the second part of the talk, we will explore new cognitive radio architectures that utilize the spectrum in a more intelligent manner. Agility and dynamic operation allow the radio to operate under extreme conditions without incurring large average power dissipation.

These architectures exploit deep sub-micron CMOS that will ultimately result in a dramatic improvement in the level of integration. Niknejad received the B.

Mesh networks making use of software-steerable directional antennas enjoy several advantages over those based on omnidirectional antennas. But until recently, the cost of an electronically steered antenna has been too high for widespread adoption.

This talk will discuss a design for a very low cost antenna based on a novel RF phase shifting device. The goal is to use a traditional infrastructure mode, However, the access points now also act as mesh routers and are connected in a multihop wireless distribution system with routing autonomously managed with a link state-based dynamic routing protocol. The client devices are unaware of the routing infrastructure and do not need any special protocol or set up.

Client mobility is handled automatically by link-layer handoffs which in turn triggers appropriate route changes. For improved capacity, the mesh routers are equipped with multiple A distributed channel assignment algorithm assigns channels to interfaces such that the requisite network topology is maintained and throughput is maximized. The talk will describe the architectural choices, routing and channel assignment protocols, and performance results in the initial hardware prototype.

Samir R. He received his Ph. He is also on the editorial board of the Ad Hoc Networks Journal. As devices with wireless networking become more pervasive, mobile ad hoc networks are becoming increasingly important, motivating the development of potentially very large ad hoc networks. The Safari project at Rice University is developing a scalable ad hoc networking architecture based on a self-organizing network hierarcy and scalable ad hoc network routing, providing self-organizing network services and integration with traditional Internet infractructure and services where available.

Safari leverages and integrates research in both ad hoc networking and peer-to-peer networking. In this talk, I will describe the design and initial evaluation of the network organization and routing components of the Safari architecutre.

Our self-organizing network hierarchy formation protocol recursively forms the nodes of the ad hoc network into an adaptive, proximity-based hierarchy of cells. Utilizing this hierarchy, the routing protocol within Safari is a hybrid of proactive and reactive routing that has very low, scalable overhead.

We have evaluated this design through analysis and simulations, under increasing network size, increasing fraction of mobile nodes, and increasing offered traffic load. David B.

Robert Morris Massachusetts Institute of Technology. The Click toolkit, for example, brings a new level of flexibility to network configuration by viewing routers as compositions of packet processing modules.

The Grid routing protocol lets collections of radio-equipped nodes automatically configure their own cooperative network, without relying on any pre-installed infrastructure; Roofnet is an experimental deployment of Grid. The Resilient Overlay Networks project allows end-system control over Internet routing, so that applications can choose their own tradeoffs among qualities such as delay, bandwidth, and reliability.

He led a mobile communication project which won a best student paper award from USENIX and he co-founded Viaweb, an e-commerce hosting service. He received his PhD from Harvard University for work on modeling and controlling networks with a large numbers of competing connections.

Network monitoring enable operators to gain value insight into network behavior, usage and performance. With the advent of small form-factor devices, falling prices, and robust protocol implementations, mesh networks are witnessing widespread deployment. The monitoring of such networks is crucial for their robust operation.

Damon relies on agents within the network to actively monitor network behavior and send this information to data repositories. In this talk, we describe the architecture of Damon and report on the performance of the IETF network based on monitoring information collected by Damon. Elizabeth M.

Richard Draves Microsoft Research. We present a new protocol for routing in multi-radio, multi-hop wireless networks. Our protocol, Multi-Radio Link-Quality Source Routing, is designed for wireless networks with stationary nodes, where each node is equipped with multiple independent radios.

The goal of the protocol is to choose a high-throughput path between a source and a destination. Our protocol assigns a weight to each individual link, and then combines the link metrics into a path metric that explicitly accounts for the interference among links that use the same channel. The path metric calculation can be tuned to either maximize throughput of the given flow or to minimize its impact on other flows. We studied the performance of our protocol by implementing it in a wireless testbed consisting of 23 nodes, each equipped with two We used combinations of We find that our protocol significantly improves throughput by judicious use of a second radio.

We also show that our protocol significantly outperforms previously-proposed routing protocols in a multi-radio environment. Most recently Rich has been working on mesh networking.

Developer Platform: Next, is the comprehensive developer platform and tooling that Mesh enables. The core of the developer platform is Azure. With identity services like Azure Active Directory and Microsoft Accounts , it brings duly authenticated and authorized users into a secure and trusted session. The Microsoft Graph continues to flow with the users to allow them to bring in their connections, content, and preferences, both from the commercial and consumer space.

Beyond the core platform, we have key AI-powered capabilities that allow Mesh to address some of the most complicated technical challenges with enabling massive multiuser online MMO scenarios for mixed reality. These include immersive presence, spatial maps, holographic rendering, and multiuser sync. Microsoft Mesh AI-powered capabilities. Mesh delivers the most accessible 3D presence with representative avatars via inside-out sensors of the devices.

The Mesh platform comes with an avatar rig and a customization studio so you can use the out-of-the-box avatars. The platform is capable of powering existing avatar rigs too with its AI-powered motion models to capture accurate motions and expressions consistent with the user's action. Alongside avatars, Mesh also enables the most photorealistic o holoportation with outside-in sensors. These outside-in sensors can be a custom camera setup like the Mixed Reality Capture Studio , which helps capture in 3D with full fidelity or it could be Azure Kinect that captures depth-sensed images to assist in producing the holographic representations.

Once the holograms are produced these can be used within Mesh-enabled apps on immersive mixed reality headsets or everyday phones, PCs, and tablets, to holoport users in their most life-like representations and deliver a sense of true presence. Spatial maps: Building apps that persist holographic content in the real world requires a common perspective of the space around each participant as well as an understanding of the physical world. Whether that is service records for a technician or wayfinding for a customer, placing holograms reliably that can persist across time, space, and devices is a common need.

This is all enabled in Mesh via Spatial maps. Prior to Mesh, each device has its own local view of the world. This framework enables content to be anchored, device point-of-views to be shared, and 3D models to be collaborated on. Mesh helps you create a map of your world that is orders of magnitude more accurate than GPS, and it can even work in places without GPS access. Additionally, Mesh can generate the same understanding aligned to the precise layout and geometry of a given object, allowing developers to easily build apps that may require overlaying objects with visual information like instructions, service records, and other important data, precisely aligned to the components of the object.

Mesh allows the choice between local stand-alone rendering or cloud-connected remote rendering seamlessly within your app, for each scene and model. This gives the flexibility to design apps that can optimize for latency vs fidelity depending on the device it is being experienced on. Found the story interesting?
