Traditional approaches for testing MANET protocols and applications prior to field experimentation often involve simulation tools or small-sized physical testbeds. However, simulation tools typically do not run in real-time and rely on simplified models rather than a real system, while physical testbeds are prohibitively expensive to build and operate. A(More)
This paper proposes Silent Networking – a new method to significantly increase the lifetimes of energy-constrained nodes, networks, and mobile user devices. With Silent Networking, each network element powers off some or all of its radio interfaces during their naturally occurring silent periods, i.e., time periods when it does not expect to originate,(More)
Emergence of mobile handheld devices with WiFi (IEEE 802.11) interfaces such as WiFi phones, WiFi-cellular dual-mode phones and PDAs (personal digital assistants), allow users to take full advantages of heterogeneous radio technologies. WiFi, however, was not originally designed for energy-constrained handheld devices. As a result, the standby times of a(More)
We propose an innovative distributed agent-based architecture for a seamless multi-layer soft handoff protocol in wireless battlefield networks. Our architecture utilizes a proactive "make before break" approach by introducing the concept of pre-computed remote Loop-Free Alternate Paths (rLFAPs) on top of local LFAPs proposed by the IETF IP Fast-Reroute(More)
One of the major QoS goals for Future Battlefield Networks (FBN) is to ensure Multi-level Precedence and Preemption (MLPP). Ensuring MLPP is difficult, partly due to the networking architecture for FBN which consists of wired “red” network connected by encrypted wireless “black” network. The security requirements for FBN do not(More)
Routing for link state routing protocols such as OSPF is determined by computing shortest-paths on the network topology graph. In conventional routing the OSPF link costs are configured a-priori before the network is deployed, and remain fixed until manually changed. If subsequently, link quality degrades or alternate links become available, routing paths(More)
This paper illustrates a methodology to evaluate model’s performance of rainfall runoff model using a tool called WETSPRO (Water Engineering Time Series PROcessing tool). Simulated results of physically based semidistributed model SWAT (Soil and Water Assessment Tool) for Kliene Nete watershed (581 km2), Belgium are considered in this study. Paper presents(More)
In the tactical Internet, inter-domain links consist mostly of unreliable and low bandwidth wireless links. To enable seamless routing across different Autonomous Systems (ASes), we propose an inter-domain Traffic Engineering (TE) scheme to reroute traffic when congestion occurs. There are two components for the TE scheme. First, a Traffic Splitting (TS)(More)
