This paper describes a field demonstration and presents the network performance of an 802.11 ground-UAV network composed of 11 ground stations, a mobile vehicle and two fixed wing UAVs, connected by two routing gateways to a legacy wired network. The network effects demonstrated include mobility, network partitions and merges, and gateway failovers. The paper presents experimental results for recorded...
So far we have developed Emergency Telemedicine System (ETS) which is a robust system using heterogeneous networks. In disaster areas, however, ETS cannot be used if the primary network channel is disabled due to damages on the network infrastructures. Thus we designed network management software for disaster communication network by combination of Mobile Ad hoc Network (MANET) and Wireless LAN (WLAN)...
MIMO based MANET has received a great deal of attention in the past decade, resulting in a number of MAC layer protocols that aim to utilize the inherent capabilities afforded by multi-antenna enabled nodes. Many of these MAC protocols look to improve on the total number of concurrent links within the network. In this paper, we present a theoretical approach for identifying the maximum number of concurrent...
A current challenge in interconnecting mobile ad hoc networks (MANETs) with backbone legacy networks is the lack of compatibility between different multicast routing protocols when using multiple gateways, due to differences in both forwarding semantics and implementations of the different protocols. We present designs and experimental results involving the interconnection of the simplified multicast...
In this demo, we showcase DiffQ - a congestion control protocol inspired by theoretical cross-layer optimization approaches. DiffQ can support congestion control for network flows that use either single-path or opportunistic multi-path routing. Our demo will focus on the performance in single-path routing environments, where contemporary end-point congestion control algorithms like TCP face severe...
Differentiated service (DiffServ) is currently the only known QoS provisioning mechanism that is compatible to in-line network encryptors (INE) for military networking applications. However, DiffServ typically assumes stable link bandwidth capacity and interconnectivity state in QoS provisioning; this is not the case in a dynamic ad-hoc mobile network environment. There will be a need for "DiffServ...
