Problem Definition
Geographic routing is a type of routing particularly well suited for dynamic ad hoc networks. Sometimes also called directional, geometric, location-based, or position-based routing, it is based on two principal assumptions. First, it is assumed that every node knows its own and its network neighbors' positions. Second, the source of a message is assumed to be informed about the position of the destination. Geographic routing is defined on a Euclidean graph, that is a graph whose nodes are embedded in the Euclidean plane. Formally, geographic ad hoc routing algorithms can be defined as follows:
Definition 1 (Geographic Ad Hoc Routing Algorithm)
Let \( { G=(V,E) } \) be a Euclidean graph. The task of a geographic ad hoc routing algorithm \( { \mathcal{A} } \) is to transmit a message from a source \( { s\in V } \) to a destination \( { t\in V } \)by sending...
