An Analytical Framework of Handoff in Wireless Mobile Network with Catastrophes
نویسنده
چکیده
Abstract — The demand for wireless mobile networks led to an increase in handoff calls. Optimum utilization of the channel should be planned as it is the limited resource for any mobile network. Poorly designed handoff schemes lead to a drastic decrease in quality of service. The study gives an analytical framework of handoff procedure when some channels are purely reserved for handoff calls. In addition to that the loss of customers due to disaster in communication network is incorporated in the model. Steady state probabilities, blocking probability of new calls and probability of forced termination of ongoing calls are found.

Handoff is the procedure providing the connection to the backbone network while a mobile terminal is moving across the boundaries of coverage of two wireless points of connection. The complexity of the handoff decision process has led to the examination of a number of traditional and pattern recognition handoff decision algorithms for wireless networks. Traditional algorithms use a received sig...
متن کاملEnabling seamless multimedia wireless access through QoS-based bandwidth adaptation
Effective support of real-time multimedia applications in wireless access networks, viz. cellular networks and wireless LANs, requires a dynamic bandwidth adaptation framework where the bandwidth of an ongoing call is continuously monitored and adjusted. Since bandwidth is a scarce resource in wireless networking, it needs to be carefully allocated amidst competing connections with different Qu...
