Cross-Layer Approaches to QoS Routing in Wireless Multihop Networks

4.1 Introduction

Popular categories of multihop networks include wireless sensor network (WSN), mobile ad hoc network (MANET), wireless mesh network (WMN), and vehicular ad hoc network (VANET). In WSNs, sensor nodes are deployed in the target area to measure specific attributes, such as temperature or pressure, and relay the measured information to a base station for processing. Sensor nodes can be deployed in large numbers and can operate autonomously without human intervention. Nodes in MANETs typically have sufficient processing and networking capabilities and can connect together autonomously and run a variety of applications. In WMNs, nodes have similar capabilities ...
