Emulating an Embedded Firewall

The Adventium Labs Embedded Distributed Firewall provides a simple interface for securely managing approved network flows between computers on a network. A "Conversation" manager provides a simple interface for managing flows, defining the connections authorized between nodes on a network. These policies are enforced in hardware embedded in the network...

Cross Layer Adaptive Control for Wireless Mesh Networks

This paper investigates optimal routing and adaptive scheduling in a wireless mesh network composed of mesh clients and mesh routers. The mesh clients are power constrained mobile nodes with relatively little knowledge of the overall network topology. The mesh routers are stationary wireless nodes with higher transmission rates and more...

Predicting the Performance of Mobile Ad Hoc Networks Using Scaled-Down Replicas

Experimentation with mobile ad hoc network testbeds is preferred to simulations for performing high fidelity testing. But, at the same time, realistic experimentation with large-scale network testbeds is more difficult, time-consuming, and expensive. To side- step some of these problems several researchers, have recently suggested experimentation on scaled-down replicas and...

Optimal Backpressure Routing for Wireless Networks With Multi-Receiver Diversity

This paper considers the problem of optimal scheduling and routing in an ad-hoc wireless network with multiple traffic streams and time varying channel reliability. Each packet transmission can be overheard by a subset of receiver nodes, with a transmission success probability that may vary from receiver to receiver and may...

Protecting Public Servers From DDoS Attacks Using Drifting Overlays

Drifting Overlays are dynamic partial network-layer overlays with traffic 'Safe houses' that enterprises can use to control, at fine granularity, the reachability and predictability of paths taken to important hosts. Drifting Overlays enable enterprises a level of control over their own Distributed Denial of Service DDoS defenses and routing choices,...

Delay Analysis and Comparison of OFDM-TDMA and OFDMA Under IEEE 802.16 QoS Framework

The delay analysis and comparison of OFDM-TDMA and OFDMA using a flow control scheme under the QoS framework of IEEE 802.16 are conducted in the work discussed in this paper. The paper investigates the maximum packet delay performance by deriving delay bounds for several multiaccess modes with different subcarrier/time-slot assignment...

On Nodal Encounter Patterns in Wireless LAN Traces

This paper explains WLAN traces from five different sources and focuses on investigation of encounter patterns between users. The authors find that typical wireless LAN users encounter with a small portion of the whole population (no more than 60% in all traces, and on average between 1:88% to 6:70%). Total...

Municipal Wi-Fi Networks: The Goals, Practices, and Policy Implications of the U.S. Case

This paper explores three broad questions about municipal Wi-Fi networks in the U.S.: why are cities getting involved, how do they go about deploying these networks, and what policy issues does this new trend raise? To explain municipal involvement, the paper points out that cities have both the means to...

Generalization of Single-Carrier and Multicarrier Cyclic Prefixed Communication

This paper describes a cyclic prefixed communication structure that is a generalization of both the Orthogonal Frequency-Division Multiplexing OFDM system and the Cyclic Prefixed Single-Carrier (CP-SC) system. By exploiting the fact that a Circulant Matrix CM is also a Block Circulant Matrix BCM, the proposed Generalized Cyclic Prefixed GCP communication...

Evaluation of 802.11a for Streaming Data in Ad-Hoc Networks

Advances in communication and processing have made ad-hoc networks of wireless devices a reality. One application is home entertainment systems where multiple Home-to-Home (H2O) devices collaborate as peers to stream audio and video clips to a household. This paper investigates the feasibility of IEEE 802.11a protocol in combination with both...

Experimental Analysis of Concurrent Packet Transmissions in Wireless Sensor Networks

This paper undertakes a systematic experimental study to analyze the effects of concurrent packet transmissions in wireless sensor networks. As expected, the measurements confirm that guaranteeing successful packet reception with high probability requires that the signal to interference plus noise ratio exceed a critical threshold. It also confirms that groups...
