“…A received signal strength (RSS) based handover algorithm introduced by [15,16] reduces handover failure rate from WLAN to cellular network based on the MT's speed and handover latency. Authors in [17,18] proposed a prediction based handover decision scheme to estimate MT dwelling time in WLAN coverage. Mobile terminal triggers handover to WLAN cell if and only if the estimated dwelling time is greater than the time threshold.…”

Abstract-Application of existing mobile telemedicine system is restricted by the imperfection of network coverage, network capacity, and mobility. In this paper, a novel telemedicine based handover decision making (THODM) algorithm is proposed for mobile telemedicine system using heterogeneous wireless networks. The proposed algorithm select the best network based on the services requirement to ensure the connected or targeted network candidate has sufficient capacity for supporting the telemedicine services. The simulation results show that the proposed algorithm minimizes the number of unnecessary handover to WLAN in high speed environment. The throughput achieved by the proposed algorithm is up to 75% and 205% higher than Cellular and RSS based schemes, respectively. Moreover, the average data transmission cost of THODM algorithm is 24% and 69.2% lower than the Cellular and RSS schemes. The proposed algorithm minimizes the average transmission cost while maintaining the telemedicine service quality at the highest level in high speed environment.

In a highly integrated ubiquitous heterogeneous wireless environment, the selection of a network that can fulfill end-users' service requests while keeping their overall satisfaction at a very high level is vital; a wrong selection can lead to undesirable conditions such as unsatisfied users, weak QoS, network congestions, dropped and/or blocked call sand wastage of valuable network resources. The selection of these networks is performed during the handoff process when an MS switches its current PoA to a different network due to the degradation or complete loss of signal and/or deterioration of the provided QoS. Traditional schemes perform the necessity of handoffs and trigger the network selection process based on a single metric such as RSS

“…The handoff algorithms based on cost-function combine multiple systems' metrics to choose the target network that offers the highest overall performance. This approach is considered optimal as compared to the other traditional approaches that rely on single system's parameter like RSS or available bandwidth to make handoff decisions [1].…”
