Abstract
Support for QoS is integral to the design of ad-hoc networks. Fluctuations in channel quality effect the QoS metrics on each link and the whole end-to-end route. In addition, the interference from non-neighboring nodes effects the link quality. QoS is thus an essential component of ad-hoc networks. The QoS requirements arise at the application layer in the form of restrictions on values of certain QoS metrics. The most commonly studied QoS metrics are bandwidth, delay and jitter. Bandwidth is the QoS metric that has received the most attention in the QoS literature. The QoS requirements are typically met by soft assurances rather than hard guarantees from the network. Most mechanisms are designed for providing relative assurances rather than absolute assurances. This chapter presents solutions and approaches for supporting QoS in ad-hoc networks at the physical, MAC, and routing layers. It also presents approaches at other layers and describes future challenges that need to be addressed to design a QoS enabled ad-hoc network.
