The Joint Tactical Radio System (JTRS) will result in a family of tactical radios all built upon a common, open software communication architecture (SCA). The JTRS SCA version 2.0 release includes waveform application programming interface (API) building blocks (BBs) that can be used to support a portable and interoperable wideband networking waveform (WNW) within a JTRS SCA-compliant operating environment (OE). This paper describes how the waveform API BBs could be used to support the porting of a WNW by describing Rockwell Collins' experience in porting its wireless-wideband networking engine (WNE) into the JTRS OE The WNE is an ad-hoc wireless networking product that has been instantiated in multiple non-JTRS radios.

When power control is employed in a Ka-band LEO satellite system featured with a Markov channel, the long loop lag induces power control gaps during channel state transition, which results in long (large-scale) burst errors. To combat it, a novel hybrid ARQ scheme is proposed in this paper, in which the side information of the turbo decoder is utilized to derive the average reliability LLR/sub l/ of the desired frame based on the iterative SOVA decoding algorithm. When LLR/sub l/ is below the specified threshold, a Go-Back-N ARQ protocol is launched. With this scheme, the large-scale burst errors are effectively detected and corrected by the retransmission; the small-scale burst errors are filtered out for the interleaving and FEC coding to correct. The simulation results show that this scheme can achieve good BER performance with small cost in throughput and delay for Ka-band Markov satellite channels.

NC3A (NATO Consultation, Command and Control Agency) has implemented an IP client for STANAG 5066 high frequency (HF) subnetwork servers, supporting unicast and multicast IP operations in an HF wireless WAN using NATO's "Profile for HF Radio Data Communications", STANAG 5066. The IP client uses the character-based Ethernet device 'TUN/TAP' to interface to the IP protocol stack in the Linux operating system. A socket-based interface between client and subnetwork is used with an IANA-registered port number. Existing code was reused from previous work at NC3A that implemented a PPP (point-to-point protocol) client for unicast IP operation. Unicast IP packets are mapped onto the ARQ service mode in STANAG 5066 Multicast IP packets are mapped onto the non-ARQ service modes with group addressing. Both IP addressing modes are multiplexed within the STANAG 5066 subnetwork and are dynamically supportable. Performance issues for TCP over low-speed/high-latency links and the usability of LAN/WAN oriented routing and QoS protocols on HF radio are also discussed. This work is being pursued to integrate modern HF protocols and waveforms into the future NATO wireless WAN for deployed forces.

The Small Unit Operations Situation Awareness System (SUO SAS) is an individual warfighter communications system that provides support for training, mission planning, mission rehearsal, mission execution, and post-action analysis activities. it provides each soldier access to comprehensive and shared situation awareness (SA) information, as well as access to battlefield applications. The SUO SAS, also, provides the individual warfighter with reliable and robust voice, video, and data communications. The SUO SAS radio network with up to 10,000 nodes is required to operate under extremely volatile tactical environments. Therefore, a robust and scaleable intranetwork architecture is needed to maintain a functional SUO network. This paper defines the SUO intra-networking architecture. The SUO intra-networking protocols include the SUO network formation protocol, the SUO link-state routing protocol, and SUO cross-tier binding protocol. The network formation protocol creates and maintains the hierarchical structure of the SUO network.

Military satellite communication can be operated with various levels of satellite onboard processing. The BER performances of the bent pipe transponder (BPT), dehop only transponder (DOT) and dehop and rehop transponder (DRT) systems with FH-MFSK modulation are compared in the presence of full-band and partial-band noise jamming and multi-tone jamming. Further, this paper investigates the BER by changing the data rates, spreading bandwidth and jamming EIRP. The numerical results show that DRT outperforms BPT and DOT and that DOT is less sensitive to uplink jamming EIRP under the full-band jamming strategy than DRT. In the partial-band jamming case, the worst case /spl rho/ (the ratio of spreading bandwidth to jamming bandwidth) is also changed according to the variation of the data rate, and the BER of DRT is more sensitive to different /spl rho/ values than DOT. Among various jamming strategies, the performance in MTJ is shown to be the worst.

In this paper, we present a delay differentiation based QoS architecture for supporting real-time multimedia services in the core-stateless IP networks. The key component of our approach is a three-level class-based scheduling scheme. Based upon it, we propose the Delay Differentiation with Earliest-Deadline-First (DD-EDF) QoS architecture. Simulation shows that our approach can achieve better end-to-end/per-hop average queueing delay performance with higher link utilization, when compared with the scheme without DD-EDF.

Mobile CDMA cellular networks for tactical applications require base-station mobility in order to provide communications on the move. Because of the mobility of the base stations and the lack of a high-speed wire-line network between base stations, handoff of mobiles among base stations is more difficult than in a commercial CDMA cellular network. In this paper, we examine the performance of the reverse links in a tactical CDMA cellular network using continuous transmission for packet data communications. In particular, we consider the effect of limited handoff capability on the reverse-link capacity of the network.

In this paper according to the analysis of the characteristics of multilevel codes (MLC) and space-time block codes (STBC), a concatenation scheme combining MLC and STBC is proposed over Rayleigh fading channels. According to the fact that the MLC system can achieve optimal performance by the BP (block partitioning) rule, the optimal set partitioning of the MLC-STBC system is investigated in this paper. After the analysis and computer simulations, it is proved that the MLC-STBC system has the same optimal set partitioning as the MLC system.

We propose a mobility-based hybrid multicast routing (MHMR) protocol suitable for mobile ad-hoc networks. The main features that our proposed protocol introduces are the following: (a) a mobility based clustering and group based hierarchical structure, in order to support stability and scalability effectively; (b) a group based (limited) mesh structure and forwarding tree concepts, in order to support mesh topology robustness which simultaneously provides "limited" redundancy and efficiency of tree forwarding; (c) a combination of proactive and reactive concepts which provide the low route acquisition delay of proactive techniques and the low overhead of reactive methods. The performance evaluation of the proposed protocol is achieved via modeling and simulation. The corresponding results demonstrate the proposed multicast protocol's efficiency in terms of packet delivery ratio, scalability, control overhead and end-to-end delay as a function of mobility, packet generation rate and multicast group size.
