Dimensions and challenges in providing QoS for wireless systems

Quality of Service (QoS) in wireless systems refers to estimation of a system with good quality of communication, service availability, channel availability, bandwidth guarantees and minimum delay etc. There are wide and variety of wireless systems that are classified into infrastructure based systems, ad hoc based systems and hybrid systems. It is challenging to maintain Quality of Service (QoS) for wireless systems. Scope of the book include: • Quality of Service for wireless systems • QoS metrics • Sequencing Technique for reducing number of collisions while accessing channel • Issue of Channel allocation • approach for reserving bandwidth in wireless networks. • flow and congestion mechanisms for wireless systems •
