Ad hoc Wireless Networks
13.1 Introduction
A wireless network consists of computing nodes which communicate using wire-
less communication channels. Wireless networks can be formed as in frastructured
or ad hoc. A static wired backbone usually consisting of host computers provides
the communication in infra-structured networks whereas nodes of an ad hoc wire-
less network communicate using multi-hop packet transfers. Two important types of
ad hoc wireless networks are the mobile ad hoc networks (MANETs) and wireless
sensor networks (WSNs). There is no fixed infrastructure in a MANET as the nodes
in such a network change their positions dynam ...
