Introduction to Wireless Multi-Hop Networks

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 intermediate 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 classified as wireless multi-hop networks. These paradigms are: Mobile Ad-Hoc Networks (MANETs), Wireless Sensor Networks (WSNs), Wireless Mesh Networks (WMNs), and Vehicular Ad-Hoc Networks (VANETs). In this chapter, we will present an overview of wireless multi-hop networks along with brief introductions to these four wireless multi-hop network paradigms.
