Optimal Channel Allocation Algorithm with Efficient Bandwidth Reservation for Cellular Networks

Abstract

As the growth of mobile users increasing in the present scenario and because of limited bandwidth available, there is a need to efficiently use the bandwidth available. The quality of service can be maximized by efficient bandwidth reservation. In this paper, the cross layer based bandwidth reservation scheme is proposed which initially reserves some amount of bandwidth for handoff flows. After that the bandwidth can be increased for handoff flows by the base station based on the user mobility. The user may not only go straight but also left, right and backwards. This paper considers all possibilities of user movements and bandwidth is reserved accordingly. Therefore making the base stations to dynamically increase the reserved bandwidth for handoffs when the initially reserved bandwidth is insufficient reduces the end to end delay and increases the throughput of the system. The proposed system performance is compared with the legacy systems and is shown to be better.

A framework for mobility prediction and high bandwidth utilization to support mobile multimedia streaming

“…Table II shows the values of the parameters used in the simulations. Similar to [10,11], new call requests are generated according to a Poisson distribution with rate λ (calls/second/user) and the minimum bandwidth granularity that may be allocated to any call is 1 bandwidth unit (BU). The call duration is assumed to be exponentially distributed with a mean of 300 sec.…”
