Performance evaluation of Manhattan model for handoff in mobile wireless networks / Shahrilazmi Abdul Samad

In the future cellular mobile systems, the steadily growing mobile subscriber community and their demand for diversity of service place great challenge on the bandwidth utilization, especially in the wireless network part, as radio spectrum is a limited resource. This project analyzes the performance evaluation of Manhattan model for handoff in mobile wireless network. The Manhattan model represents a typical city environment that is characterized by alignment of building blocks with streets cutting apart neighboring blocks. This model enables us to evaluate the performance criteria such as call blocking and handover probabilities due to the effect of averaging and hysteresis on the handoff process. Handoff is one of the most critical features of a network because it is directly related to the system capacity and performance of a cellular network system. Next generation high-speed cellular networks are expected to support multimedia applications which require quality of service (QOS) provisions. Dynamic Channel Assignment (DCA) scheme have been proposed with subset of total available channel reserved for use handovers shows significantly better result in term of lost call during handover. Detailed simulations model using MATLAB software is carried out to evaluate the performance of such systems for the proposed methodology compared to other channel allocation technique.
