Introduction to Wireless Multi-Hop
Networks
Abstract Although wireless communication has brought many benefits since its
introduction, it has some drawbacks compared to its wired counterpart. Wireless
communication suffers from interference, low bandwidth availability, low data
rates compared to wire line, and signal fading. Such drawbacks led to limitations
in the transmission range of wireless devices. For a node to send a packet to a
destination out of its transmission range, the node should depend on some inter-
mediate node(s) for relaying the packet. Such a paradigm is known as multi-hop
communication and the wireless networks adopting this communication paradigm
are known as wireless multi-hop networks. Four network paradigms can be clas-
sified as wireless multi-hop networks. These paradigms are: Mobile Ad-Hoc
Networks (MANETs), Wireless Sensor Networks (WSNs), Wireless Mesh Net-
works (WMNs), and Vehicular Ad-Hoc Networks (VANETs). In this chapter, we
will present an overview of wireless multi-hop networks along with brief intro-
ductions to these four wireless multi-hop network paradigms.

1.1 Overview
Generally, wireless communication refers to the use of untethered communication
(e.g., infrared, acoustic, or radio frequency signals) for sending and receiving data
between devices equipped with wireless interfaces [ 1 ]. Since its introduction,
wireless communication has been a revolution for communication and networking
technologies with the great advantages that it provides in comparison to its wired
counterparts. With no wires needed for end-to-end communication, wireless
