A heterogeneous wireless network consists of various wireless networks [eg, Worldwide
Interoperability for Microwave Access (WiMAX) and Wireless Fidelity (WiFi)] and cellular …

In the present paper, we develop an adaptive algorithm for call admission control in wireless
networks. The algorithm is built upon the concept of guard channels and it uses an …

In a heterogeneous wireless network (HWN) that consists of various wireless networks (eg,
WiMAX and WiFi) and cellular communications (eg, B3G and 4G), vertical handoff acts as an …

Mobile users are demanding fast and efficient ubiquitous connectivity supporting data
applications. This connectivity has to be provided by various different networks and …

In this paper, a distributed adaptive guard channel reservation (DAGCR) scheme is
proposed to give priority to handoff calls. This scheme is built upon the concept of guard …

In this paper a new control-period-based distributed adaptive guard channel reservation
(CDAGCR) technique is proposed to meet the call admission level quality-of-service (QoS) …

The IEEE 802.16 standard adopts a centralized resource-allocation mechanism to poll
nodes with three polling modes, ie, the unicast, multicast, and broadcast polling modes …

Many mechanisms based on bandwidth reservation have been proposed in the literature to
decrease connection dropping probability for handoffs in cellular communications. The …

Call admission control in mobile cellular networks has become a high priority in network
design research due to the rapid growth of popularity of wireless networks. Dozens of …

The demand and amount of data transfer in heterogeneous wireless network increases as
the techniques of the third/fourth generation mobile communications (3G/4G) are progressed …
