Description:
Resource allocation and management is the fundamental key in providing better service using mobile communication systems. This paper review the schemes for providing Quality of Service (QoS) in mobile wireless network environment. The paper will evaluate a total of four schemes this include Fault Tolerant Dynamic Allocation Scheme which deals with the methods of reusing the channels effectively between two adjacent cells to avoid co-channel interference, second is Call Admission Control Scheme which deals with pre-blocking of calls based on the available bandwidth for handling calls, third scheme is Mobility Prediction Scheme which collects the information of the mobile host while travelling in a vehicle and store the information into a database, and lastly Dynamic Allocation using Renegotiation Scheme where the bandwidth usage changes dynamically depending on its availability. These schemes are used in different environment to increase the quality of services of mobile communication. Each scheme has its strong and weakest point depending on the parameters they are to analyze.
