## 2 Network Model and Problem Description
### Analysis of Current Advanced Network Routing Protocols  
Currently, advanced network routing protocols mainly include DSDV (Destination-Sequenced Distance-Vector Routing) [1], AODV (Ad-hoc On-demand Distance Vector), LAR (Location Aided Routing), STG (Space-Time Graph) routing framework, CBMANET (Control-Based Mobile Ad-hoc Network) [2], and the command and control information network-tactical system WIN-T [3,4]. The DSDV protocol has a poor convergence performance when the network topology changes frequently [5]. Nodes must periodically broadcast updated information no matter how variable the network traffic is and whether or not they need to send data. As the number of nodes in the network increases, the capacity, overhead, and bandwidth of the routing table also increase accordingly. The DSDV protocol requires that each node be saved to the routing of all nodes in the network; in this way, the redundant routing entries can cause a waste of resources. The AODV protocol is an improved on-demand routing protocol based on the DSDV protocol; this protocol has a strong real-time performance but weak anti-interruption capability. The LAR protocol is a geo-location assisted routing protocol. It is also an on-demand routing protocol based on the source routing [6]: the node obtains its own current location (x,y) through GPS, the source node adds the current time and location to the sending route request, the destination node adds its current time and location in the route reply, and the node that forwards the request or responds to the packet can obtain the location information of the source node or destination node. The DTN (Disruption Tolerant Network) constructs the space-time diagram from the space-time routing table, converts the time-dependent network into classical static network problems, and then uses the shortest path algorithm to solve the path between node pairs [7]. This protocol has a strong capability to resist network interruption, but it has a low data transmission rate and low real-time performance. The CBMANET protocol self-perceives and chooses the optimal frequency and path during maneuvering, and can also store information in temporary network nodes until the connection recovers, so there is no need to worry about signal interruption and delay; however, it has the disadvantage of a low transmission rate [8]. The command information network tactical system WIN-T routing protocol provides unprecedented network throughput and control (fast-stop communication and Satcom-on-the-move) through a comprehensive approach and provides a joint system for managing and controlling WIN-T node services [9,10]. To sum up, the parameter selection of the general AODV network is not suitable for awareness combat networks, and may even lead to a significant decline in network performance; DTN networks are helpful for the stable operation of awareness combat networks. However, if the network is established completely according to the DTN strategy [11,12], it is difficult to guarantee the real-time transmission of data. The integrated combat network provides technical support for future unmanned military operations, but it cannot effectively meet the requirements of real-time data transmission under high-speed mobile conditions. Therefore, this paper is of great application value for researching the routing protocol and its implementation method for awareness combat networks.
