Application Background

The Distance Vector Algorithm is a routing algorithm frequently employed in dynamic routing protocols. Its fundamental principle involves using vector superposition to obtain and calculate routing information. A distance vector essentially treats each routing entry as a vector composed of a destination and a distance (measured using a Metric). Each router acquires routing information from its neighbors and superimposes its own distance vector (from itself to that neighbor) onto each routing entry, thereby forming its own routing table [1]. In code implementation, this typically involves maintaining distance tables and periodically exchanging routing updates with neighboring nodes.

Key Technology

Each node measures distances to its neighbor nodes and determines the relative positions of network nodes through multi-hop forwarding and distance information exchange. This represents the strategy adopted by static wireless network localization algorithms. For existing mobile ad-hoc networks, including vehicular networks, localization methods convert dynamic network positioning problems into static positioning models through sampling approaches. Algorithm implementation often involves iterative distance calculations and position refinement through triangulation or multilateration techniques.

Additionally, other localization algorithms such as signal strength-based methods or time difference-based approaches can be considered to enhance the accuracy and stability of network positioning. These alternative methods might involve RSSI (Received Signal Strength Indicator) measurements or TDOA (Time Difference of Arrival) calculations in their code implementations.
