# Research on Communication Stability of Inter-Cannonball Network Based on OPNET
## 1 Introduction
This research investigates the relative distance and velocity between munitions and constructs the trilateration localization integrated (TLM) with multidimensional scaling (MDS) algorithm to accomplish cooperative localization of three-dimensional, airborne, networked weapons in an ad hoc network. It boasts greater localization precision and a quicker con

This accomplishes node localization in the inter-cannonball network, but the lack of inter-cannonball information exchange prevents it from achieving sophisticated cooperative strikes. [PERSON] et al. [18] present an innovative three-dimensional guiding approach based on clock synchronization algorithms to guide the munition for cooperative attack by computing the munition's normal phase acceleration in both horizontal and vertical planes. This solution overcomes the issue of non-connection and even communication interruption in cooperative guiding of loitering munitions induced by packet loss and delay. However, the change in attack target after the original one gets destroyed is not considered. Terminal-sensitive cannonballs are primary stage intelligent cannonballs that use end guidance to strike area targets. Uncertainty in the intersection state between it and the target makes it difficult to calculate the laser return energy. In [19], the authors provided a novel calculation technique for laser echo power based on a laser circumferential scanning detection mechanism, establishing a calculation function for the laser echo power reflected off the ground target's surface. The terminal-sensitive cannonball only has ballistic end guidance, which cannot realize the cooperative strike of multiple munitions against multiple targets, and here lies the advantage of the inter-cannonball network, which can develop strike strategies through inter-cannonball communication and realize a cooperative strike. Disaster area network (DAN) suffers the same issues of node loss and communication stability with inter-cannonball networks. However, with a shorter life duration, the inter-cannonball networks are less demanding in terms of energy-efficient communication. To combat the impacts of topology changes in node networks and provide dependable and energy-efficient communication, it is required to enhance latency, decrease overhead, limit energy consumption, preserve mobility, and boost bandwidth for multimedia applications. [PERSON] et al. [20] studied several routing protocols and compared their properties in terms of latency, overhead, throughput, topology, and mobility models. The performance of MANET is significantly affected by network node mobility and resource limits, where node mobility impacts link stability and node resource constraints may lead to congestion. [PERSON] et al. [21] came up with a topologically adaptive ad hoc on-demand multipath distance vector (TA-AOMDV) routing protocol that takes into account node resources, such as remaining energy, available bandwidth, and queue length of nodes, as well as the probability of connection stability, and simulated several scenarios on the NS2 platform. In high-speed node networks, the findings indicate that on-demand multipath routing protocols have considerable promise for supporting quality of service. This paper examines the effects of node speed, data rate, and number of nodes on network communication, but disregards the effect of node failure rate. A stable communication network is a foundation for achieving inter-cannonball information sharing and completing coordinated strikes. For the characteristics of the inter-cannonball network: with the high failure rate of cannonball nodes, extensive movement range, and short striking distance, we establish the network topology and provide the protocol framework of its communication network and obtain the influence consequence of failure rate and node movement speed on the inter-cannonball communication network.
