A technical roadmap for academic research, presented in an information visualization style with a clean white background. The central element is a circular closed loop formed by four clockwise arrows connected end-to-end, representing the four cyclical stages of the research. Inside the loop, the four stages are labeled clockwise from top to bottom: '1. Theoretical Origin Tracing and Genealogy Construction,' '2. Element Identification and System Refinement,' '3. Translation Mechanism and Method Construction,' and '4. Empirical Verification and Theoretical Improvement.' Branching lines extend outward from each stage module, connecting to icons and keywords representing the core methods used in that stage.

Stage 1 connects to: an ancient book icon (documentary research), an icon of superimposed landscape painting and map (iconographic analysis), and an icon comparing different city plan views (typological comparison).

Stage 2 connects to: an icon juxtaposing poetic text and a simple mountain sketch (poetic and pictorial corroboration), an icon of superimposed satellite imagery and historical maps (visual form analysis), and a questionnaire speech bubble icon (perception survey).

Stage 3 connects to: an icon of abstract geometric figure evolution (design prototype deduction), a computer screen displaying a 3D landscape scene icon (multi-media context construction), and an illustrated book icon (artistic guidelines).

Stage 4 connects to: a drawing board and design drawing icon (design-based research), and icons representing divergent and convergent thinking (critical reflection).

At the bottom of the diagram, an arrow extending from the loop points to the final outcomes: 'Regional Design Theoretical Framework and Method System,' 'Design Guidelines and Strategy Set,' and 'Empirical Design Achievements.'

The overall color scheme is stable, using primarily dark blue, gray, and academic green, with smooth lines and clear fonts. The style is inspired by charts and diagrams found in top academic journals.

Drawing Topic: Create a comparative schematic diagram for an academic paper, clearly illustrating the differences in topology and organization among centralized networks, peer-to-peer Ad-hoc networks, and clustered Ad-hoc networks.

Core Requirements:

Professionalism: Adopt a concise and standardized style common in computer or communication field papers (e.g., using simplified styles resembling Simulink or Cisco network icons).

Comparability: Arrange the three network structures side-by-side for intuitive comparison.

Accuracy: Accurately reflect the core characteristics of each type of network in terms of node roles, connection relationships, control flow, and organizational logic.

Detailed Composition Requirements:

I. Overall Layout

Divide the canvas horizontally into three columns, drawing each network structure in each column, and clearly label the titles: "(a) Centralized Network," "(b) Peer-to-Peer Ad-hoc Network," and "(c) Clustered Ad-hoc Network."

Use consistent visual elements (such as node shapes and line styles) to ensure stylistic consistency.

II. Specific Drawing Standards for Each Network

1. (a) Centralized Network

Core Node: Draw a significantly different icon (e.g., larger or different shape/color) at the center of the topology, labeled as "Server/Base Station" or "Access Point (AP)."

Terminal Nodes: Distribute multiple icons of uniform shape and size evenly around the central node, labeled as "Client" or "Terminal."

Connection Method: All terminal nodes are individually connected to the central node with straight lines; there are no direct connections between terminal nodes. The connecting lines can be slightly star-shaped.

Key Representation: Emphasize that all communication must pass through the central node (consider using arrows to indicate the direction of data flow, converging at the center).

2. (b) Peer-to-Peer Ad-hoc Network

Nodes: Draw 6-8 icons of completely identical shape and size (e.g., circles), distributed randomly or in a grid pattern, each labeled as "Node."

Connection Method: Nodes are interconnected by multiple straight lines based on their relative positions, forming a mesh topology. The connection density should be moderate, reflecting the possibility of "multi-hop" communication.

Key Representation: Emphasize the equality of nodes and the decentralization of connections. No cluster heads or central nodes are needed.

3. (c) Clustered Ad-hoc Network

Node Grouping: Divide the nodes in the entire area into 2-3 distinct groups (clusters).

Cluster Head Nodes: In each group, distinguish one node's shape or color from other nodes in the same group (e.g., using a hexagon or fill color), and label it as "Cluster Head (CH)."

Member Nodes: Label other nodes within the cluster (of consistent shape) as "Member Node" or "CM."

Connection Method:

Intra-cluster: All member nodes are connected to the cluster head node of their cluster with straight lines (forming a local star topology).

Inter-cluster: Different cluster head nodes are connected with straight or dashed lines to represent inter-cluster routing.

Ordinary member nodes are not directly connected to nodes in other clusters.

Key Representation: Clearly demonstrate a two-level hierarchical structure (centralized management within clusters, peer-to-peer or on-demand connections between clusters).
