https://doi.org/10.1007/978-3-0348-6576-0. In each round all data from all nodes needs to be transmitted to an information sink for processing. Because of limited transmission ranges of the nodes, multi-hop routing techniques are applied to transmit the data from all nodes to the sink. Since different nodes partially monitor the same spacinerve-sparing 发表于 2025-3-29 03:18:16

Der Weg zur Meisterschaft in der Führungtric routing can use positional information to pass packets efficiently to target nodes. Tasks like measuring temperature or humidity levels of a certain area can only be fulfilled, if each sensor node knows its geographic position or at least an approximation of it.

Trust Mechanisms and Reputation Systems,Most of the approaches for ad hoc networks assume that the nodes readily and honestly follow the protocol. Unfortunately, this assumption does not always hold in reality. Misbehaving in ad hoc networks can take place at different levels of the system architecture:
