Advancing the readiness level of 5G technologies requires hardware development activities, where the infrastructure has outmost importance. In this paper, we present multicore ARM-DSP based 5G technology development platform which will expedite commercializing the findings of the 5G researches. In the proposed platform, multicore DSP processors with enourmous signal processing capabilities are used...
Mobile tactical MANETs are interconnected via a quasi-static backbone network (QSN) that is relatively stationary and has substantial radio bandwidth capability. Because of high mobility and terrain sensitivity, the bandwidth available to mobile nodes within the MANET may vary significantly over time. During the periods where the bandwidth available is reduced, MANET nodes may be unable to handle...
In this paper , we present a flexible, modular architecture to combine various link state related measurements and prediction algorithms in order to accurately predict link failure in MANETs, while keeping bandwidth and energy overhead low. Our architecture can automatically adjust to varying environment, measurement availability, and prediction algorithm accuracy by dynamically adjusting and learning...
This paper presents an integrated approach to IP fast reroute (IPFRR) of both unicast and multicast paths in wireless mobile networks. A distinct feature of the proposed approach is that, instead of modifying existing routing protocols, it employs a soft handoff technique, i.e., temporarily installs pre-computed Loop Free Alternative Paths (LFAPs) until the co-existing routing protocol converges to...
In this paper, we propose a novel approach, which is termed heterogeneous intelligent filtering (HIF), for intelligent control and application data filtering in multi-domain heterogeneous networks. HIF creates intelligent gateways to rapidly and autonomously adapt the flow of information content to the changing mission needs and network characteristics. HIF employs a MANET management protocol (termed...
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 practical method is to use emulation tools...
There has been increased research interest in providing uniform distribution of autonomous mobile nodes controlled by active running software agents over an unknown geographical area in mobile ad-hoc networks (MANETs). This problem becomes more challenging under the harsh and bandwidth limited conditions imposed by military applications. In this framework, the software agent running at the application...
In this paper, we present two loop free alternative path (LFAP) computation algorithms for the seamless soft handoff (SHO) architecture proposed in [5] and its performance for tactical wireless mobile ad hoc networks. The proposed handoff architecture consists of several key components such as LFAP computation module, link quality prediction module, and link monitoring module. The key idea of the...
Dynamic survivable resource pooling (DSRP) is a new mechanism to improve the survivability and reliability in distributed wireless mobile robotics systems. DSRP is based on a virtual backbone, which is a highly distributed, scalable, and survivable network, formed and maintained through one-hop beacons among mobile robots. We implement the DSRP mechanism in our FPGA-based distributed robotics testbed...
To perform optimizations as the network changes dynamically, distributed network agents rely on information that is dispersed in the network. A data dissemination service for the agents can benefit from data filtering at selected nodes in a data distribution tree. Controlled dissemination filter (CDF) offers an efficient filtering functionality such as sifting, collection, aggregation, and scoping...
Dynamic survivable resource pooling (DSRP) is a new mechanism to improve the survivability and reliability in distributed robotics systems. DSRP is based on a virtual backbone (VB), which is a highly distributed, scalable, and survivable network, formed and maintained through one-hop beacons among mobile robots. We implement the DSRP mechanism in our FPGA-based distributed robotics system and demonstrate...
We present a probabilistic model of the stability of a virtual backbone in ad hoc networks. The model allows the computation of several metrics characterizing the dynamics of a node's random movement: (1) average time for the number of link changes of the node (i.e., instances of link creation and failure) or just failures to either drop below or exceed a given threshold, and, analogously, (2) average...
