“…For the remainder of the paper, we will use the channel model defined by the LOS component in (7) and the Rayleigh component in (12), which implies a UAV equipped with a ULA. The ULA could be oriented along either the fuselage or the wings of the UAV, the only difference being a 90 • change in how we define the heading angle.…”

“…The ULA could be oriented along either the fuselage or the wings of the UAV, the only difference being a 90 • change in how we define the heading angle. Extensions of the algorithm and analysis to different array geometries would require one to use a different expression for (7), which is straightforward, and to derive a different spatial correlation matrix R r , which is more complicated.…”

In this paper we consider a collection of single-antenna ground nodes communicating with a multiantenna unmanned aerial vehicle (UAV) over a multiple-access ground-to-air wireless communications link. The UAV uses beamforming to mitigate the inter-user interference and achieve spatial division multiple access (SDMA). First, we consider a simple scenario with two static ground nodes and analytically investigate the effect of the UAV heading on the system sum rate. We then study a more general setting with multiple mobile ground-based terminals, and develop an algorithm for dynamically adjusting the UAV heading in order to maximize a lower bound on the ergodic sum rate of the uplink channel, using a Kalman filter to track the positions of the mobile ground nodes. Fairness among the users can be guaranteed through weighting the bound for each user's ergodic rate with a factor inversely proportional to their average data rate. For the common scenario where a high K-factor channel exists between the ground nodes and UAV, we use an asymptotic analysis to find simplified versions of the algorithm for low and high SNR. We present simulation results that demonstrate the benefits of adapting the UAV heading in order to optimize the uplink communications performance. The simulation results also show that the simplified algorithms perform near-optimal performance.

“…2 The MR sends a binding update message, which contains the CoA of the MR, the network prefix of the mobile network along with the R flag set to 1, to the home agent (HA) of the mobile network. 3 The HA maps the network prefix of the mobile network to the CoA of the MR. 4 The HA sends a binding acknowledgement message to the MR.…”

To achieve information superiority in the theater of operations, establishing a robust communication infrastructure is unquestionably required. Although many studies related to tactical network architectures and requirements have been conducted, detailed technical approaches remain open research areas. In particular, routing and mobility management to ensure a robust communications infrastructure in a tactical network have not been studied extensively. In this paper, the architecture of IPv6-based tactical network is designed based on commercial technologies, which can be developed at a low cost and in short time. Major movement patterns of network nodes and networks in the tactical network are also taken into account. Based on the proposed architecture and movement patterns, a method of routing and mobility management is proposed. In addition, a tactical network testbed is simply established by implementing the proposed methods, and the functions of the routing and mobility management are also verified to work well in the testbed.
