Description: Geometric routing is an approach that uses geometric principles to optimize data routes in networks and communication systems. This method is based on representing the nodes and connections of a network as geometric entities, allowing the application of algorithms that minimize distance and maximize efficiency in information transmission. Through techniques such as triangulation and trajectory optimization, geometric routing seeks to solve complex connectivity and traffic problems in environments where the network topology may be irregular or dynamic. This approach is particularly relevant in wireless networks and sensor network planning, where physical limitations and environmental variability can affect communication quality. By integrating concepts from geometry and graph theory, geometric routing not only improves data transmission efficiency but also contributes to reducing latency and energy consumption, critical aspects in the era of massive connectivity and the Internet of Things (IoT).
History: Geometric routing began to gain attention in the 1990s when researchers started exploring more efficient methods for routing in ad hoc and mobile networks. One significant milestone was the development of algorithms that used geometry to determine optimal routes in environments where the network topology was constantly changing. As wireless network technology advanced, geometric routing became an active research area, with numerous studies proposing new techniques and algorithms to enhance the efficiency and robustness of communications.
Uses: Geometric routing is primarily used in wireless networks, sensor networks, and in Internet of Things (IoT) applications. Its ability to adapt to dynamic topologies makes it ideal for environments where nodes may move or change state. Additionally, it is applied in the planning of communication networks where route optimization is crucial to ensure efficient and low-energy data transmission.
Examples: An example of geometric routing is the GPSR (Greedy Perimeter Stateless Routing) algorithm, which is used in ad hoc networks to determine routes based on the geographic position of nodes. Another case is the use of geometric routing in sensor networks, where data is transmitted efficiently between nodes distributed over a wide area, optimizing energy consumption and latency.
