Handoff among healthcare providers has been recognized as a major source of medical errors. Most prior research has often focused on the communication aspects of handoff, with limited emphasis on the overall handoff process, especially from a clinician workflow perspective. Such a workflow perspective that is based on the continuity of care model provides a framework required to identify and su...

Next generation wireless networks must be able to coordinate services between heterogeneous networks through multi-mode mobile terminals. Such heterogeneity poses a challenge to seamless handover since each access network has different operations. In this paper, the policies of multiple metrics for handoff to permit connectivity across UMTS and WLAN/WiMAX are designed. Moreover, how to select a...

The 2G CDMA IS-95A cellular networks have been deployed for almost 8 years. Although the system design rules and operating procedures for voice services (i.e., IS-95A services) are well established and understood, with the launch of cdma2000 1x high-rate data service worldwide in year 2002, these rules and procedures need to be re-examined. We have built a complete 3G cdma2000 1x cellular simul...

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...

According to the characteristics of heterogeneous networks and user demand for seamlessly connection, the necessity of handoff to WLAN was researched. First of all, in order to reduce the influence of shadow fading on received signal strength (RSS), a smoothing algorithm based on support functions was proposed. Then, considering the context of mobile terminals and networks, and by using probabi...

Location aware handoff algorithms have a much better performance than the traditional algorithms in terms of the number of handoffs and the handoff delay (crossover point). As they do not pay attention to the received signal strength (RSS), it is not clear if they also maintain the best throughput in the case of wireless data networks. In this paper, we evaluate the tradeoffs between the unnece...

In WMN, handoff is a significant parameter of research. Whenever a mesh client leaves the range of serving mesh router and searches for accessing a new router based on good SNR (signal to Noise) ratio, a handoff procedure takes place. During mobility, packet transmission may enhance the number of security threats and network performance degradation issues which needs a secure routing protocol t...

In CDMA mobile cellular systems, wireless quality is improved by soft handoff techniques. However, it requires to hold multiple channels of cells, which is likely to increase call blocking at wired channels. It is therefore necessary to consider the entire system including the wired and wireless portions of systems for investigating an effectiveness of the soft handoff. The effect of interferen...

An adaptive resource reservation and handoff priority scheme, which jointly considers the characteristics from the physical, link and network layers, is proposed for a packet switching Multicode (MC)-CDMA cellular network supporting multimedia applications. A call admission region is derived for call admission control (CAC) and handoff management with the satisfaction of quality of service (QoS...

The Mobility in wireless cellular communication systems is its backbone so as to enhance the quality of service and maintain the continuous service. Handoff is an important task in maintaining the continuity of call in cellular systems and its failure can result in ongoing call termination. In cellular mobile networks, the coverage region is divided into smaller cells in order to achieve high s...
