In this paper, we introduce a handoff scheme for data mobile cellular radio systems. A
steady-stale traffic model is established and an analytical model of the system performance …

In mobile (wireless) networks, one major concern about quality of service (QoS) is call
dropping, where a handoff call is dropped due to insufficient wireless resources. Previous …

We propose an analytical modeling for integrated voice/data wireless networks with priority
reservation and preemptive priority procedures. In our scheme, calls are separated into …

Mobility is one of the major issues in the performance characterization of wireless
communication systems. Wireless communication systems encounter failures. These failures …

Handoff is the mechanism that transfers an ongoing call from one channel to another
channel within a cell/sector or when user moves from one cell to another cell. Handoff is the …

Handoffs in a mobile cellular communications environment will become an increasingly
important issue as cell sizes shrink to accommodate the ever-growing service load …

One way of improving the performance of a cellular network is to build a second tier (layer)
called the macrocell on top of the single-tier called the microcell. Multi-tier cellular networks …

Handoff is one of the key elements in ensuring quality of service (QoS) in mobile wireless
networks. Handoff connections generally have higher priority than new connections …

In this paper, we propose to use a dynamic load balancing scheme that utilizes fixed relay
stations placed in a cellular geographical coverage area to improve the handover …

Next Generation Wireless Systems (NGWS) include co-existence of current wireless
technologies such as WLANs, WiMAX, General Packet Radio Service (GPRS) and Universal …
