- Hierarchical Routing: In hierarchical protocols, nodes are divided into struc-
tured layers (such as clusters and trees), with the nodes in a layer collecting data
from a lower layer, aggregating this data to reduce the number of transmissions
and then sending the aggregated data to an upper layer. 2 In this type of network,
nodes are usually assigned different roles depending on their layer of operation
and they may have different capabilities based on their role in the network.
• Position-Based Routing
Position-based routing protocols depend on the use of position information for
forwarding packets. In this type of network, nodes are addressed by their geo-
graphical location and it is assumed that the nodes are aware of their locations by
using GPS or other localization techniques. To determine the current position of
the intended destination, the source node uses a location service to get the position
and includes it in the packet's destination address. Mobile nodes register their
current position with the service [ 3 ].
Wireless Mesh Networks
Routing protocols in a WMN can be classified with different taxonomies. For
example, protocols can be classified based on: route discovery (proactive, reactive,
or hybrid), network variations (static or dynamic), protocol management (dis-
tributed, centralized, or hybrid), etc. Since the main goal of a WMN routing
protocol is providing guaranteed QoS and satisfying the network performance

It may be the sink or another layer for further aggregation.
