Mobile, multiple-hop packet radio networks must route packets through several radios in order to deliver packets to their destinations. Least resistance routing (LRR) is specifically designed for routing packets in a tactical packet radio network. A unique feature of LRR is that it incorporates side information into the routing protocol for the purpose of detecting the presence of interference. The routing tables are adjusted to avoid particular radios and regions of the network that are subjected to high levels of partial-band or multiple-access interference. A simulation of a frequency hopping packet radio network using the SINCGARS radio is utilized to examine the performance of LRR in a realistic tactical environment. The model of the SINCGARS radio allows for greater detail in accounting for mobile partial-band jamming and FH multiple-access interference than has been possible in previous investigations. Both link and transport layer acknowledgments along with retransmission of dropped packets are modeled. The performance of LRR is compared to a conventional shortest path routing algorithm. LRR algorithms using both node and link resistance measures are investigated as well as a number of different routing metrics. Networks with both static and mobile user topologies are simulated.","PeriodicalId":398935,"journal":{"name":"Proceedings of the 1996 Tactical Communications Conference.

The process and observation noise vectors are assumed to be zero mean white Gaussian processes of appropriate intensities. After sampling the system with an allowable sampling period, the dynamics of the aircraft and the observation vector are expressed in the sampled-data form. Our goal is to optimally estimate the states of the aircraft by means of minimizing the mean squared error on the basis of the observed output. Although the optimal solution to the problem can be furnished by a standard Kalman filter, the implementation of this solution requires an estimator which incorporates a full order Riccati equation. Unfortunately, due to the speed and memory limitations of the flight computer, this solution is not practically feasible. Therefore, any reduction in the size of computation is highly desirable if the Kalman filter solution is to be implemented in real time. Moreover, the standard Kalman filter solution is ill-conditioned since the magnitude of the noise covariance matrices are inversely proportional to the small sampling period, making the magnitude of the covariance matrices relatively large compared to those of the system matrices. Consequently, serious numerical difficulties are expected if the filter gain coefficients are to be computed on the basis of the full order Riccati equation. We propose a technique which alleviates both the high dimensionality and the ill-conditioning associated with the problem. Our approach is based on the singular perturbation results.","PeriodicalId":398935,"journal":{"name":"Proceedings of the 1996 Tactical Communications Conference.

The solution to this dilemma requires a communications plan that works! Creating and maintaining a tactical communications plan is a complex task. The communications planner must organize the networks and net membership, distribute frequencies, IDs, callsigns, keying material, track distribution, and create communications-electronics operating instructions (CEOI). To complicate the planning procedure, the battlefield is a very dynamic environment. This requires that tactical communications, and thus, the communications plan be adaptable to ever-changing conditions. Timely, accurate, and traceable distribution is also needed. An automated tool is needed to keep up with these demands. The automated system must be fast, portable, scaleable, and easy to use. It must be modular and easy to expand (e.g., new equipment type, additional analysis and/or functionality). To build an automated tool, you must first understand the procedures and problems of the manual method. You may then use this information to create a tool to help automate the procedures and to solve the problems. ITT developed the communications management system (CMS) in response to the need for an automated communications planning tool. The CMS system consists of one or more PCs, printers, software, and associated cables.","PeriodicalId":398935,"journal":{"name":"Proceedings of the 1996 Tactical Communications Conference.

The functions of the RF receiver are to monitor the RF spectrum, detect the presence of RF pulse signals, and to generate an output pulse signal. The output signal is used to measure the threshold stability and the pulse width of the detected signals. The receiver was modeled as a complex baseband system using the Signal Processing WorkSystem (SPW). The analysis was performed to (1) predict the system performance of an ideal detection system; (2) verify results obtained with a prototype engineering model; and (3) to evaluate design modifications proposed to improve the accuracy of the output signal generation. The analysis results indicate that the simulation model provides an accurate representation of the receiver. The simulation results differ from analytic results by less than 0.05 dB. The simulation results predict the ideal receiver operating characteristic (ROC) should be 0.8 dB more sensitive than the prototype engineering model. The simulation results predict a threshold stability accuracy that is less than 2 nsec different than the prototype engineering model results. Finally, the simulation results predict that the proposed design changes would enhance the pulse generation accuracy. This result was confirmed by modifying the prototype engineering model.","PeriodicalId":398935,"journal":{"name":"Proceedings of the 1996 Tactical Communications Conference.
