3.5 Summary
In this chapter, we discussed the distinguishing features of the wireless multi-hop
network paradigms by presenting a detailed discussion of the design consider-
ations and popular classification of each paradigm's routing protocols. As well, for
each paradigm, we presented the core routing components, along with some
functionalities of each component and some representative protocols that adopt
these functionalities. We summarize the core components and functionalities to
provide a clear comparison among the routing functions of the four types of
wireless multi-hop network. The core components and functionalities of MANETs,
WSNs, WMNs, and VANETs are illustrated in Figs. 3.5 , 3.6 , 3.7 , and 3.8 ,
As depicted in the figures, there are some common functionalities for the
various wireless multi-hop networks as they all share the same skeleton presented
in Chap. 2 . However, because each network paradigm has its own environmental
features and requirements, there are some unique functionalities that distinguish
each network paradigm from the other wireless multi-hop paradigms. These
Route Discovery
Distance Vector
Link State
Deterministic Route
Route Selection
(the hop count metric is the most common)
Route Representation and Data Forwarding
Exact Route
Source Routing
Route Guidance
Route Maintenance
Route Refreshing
Route Failure Handling
Route Invalidation
