“…The availability analysis validates the proposed simulation model. Average lifetime within a state is plotted in Figure 13b a state is proportional to mean connection lifetime as shown in (10), it increases linearly with an increase in average connection lifetime. Mean handoff delay, taken as the mean state processing delay per connection, is also plotted in Figure 13c.…”

“…FIS considers bandwidth, velocity and number of users as decision parameters in the handoff process. The fuzzy logic-based vertical handoff decision procedure presented in [10] considers three main input parameters, namely, received signal strength, cost and bandwidth. These parameters are dynamically evaluated and compared to achieve optimal handover.…”

“…These parameters are dynamically evaluated and compared to achieve optimal handover. However, the schemes proposed in [9,10] do not consider the QoS requirements of the applications being serviced. A context-aware handover decision using knowledge about context of mobile devices, users and networks, such as user preferences, application requirements, network parameters, link quality for decision making and based on user perceived QoS trigger is presented in [11].…”

Next generation networks are envisioned to be heterogeneous in nature with an increase in demand towards ubiquitous services in wireless networks. As various networks have widely different characteristics, it is difficult to maintain the quality of service (QoS) after executing a handoff from one network to another network. Maintaining the QoS, based on applications, during the handoff in an heterogeneous networks needs an intelligent handoff decision mechanism. This article proposes a QoS-aware fuzzy rule-based vertical handoff mechanism that makes a multi-criteria-based decision, found to be effective for meeting the requirements of different applications in a heterogeneous networking environment. The QoS parameters considered are available bandwidth, end-to-end delay, jitter, and bit error rate. A new evaluation model is proposed using a non-birth-death Markov chain, in which the states correspond to the available networks. Simulation results show that compared to other vertical handoff algorithms, the proposed algorithm gives better performance for different traffic classes.

Two different relay modes are defined in IEEE 802.16j WIMAX standard: transparent mode and non-transparent mode. IEEE 802.16j standard supports mobile station mobility; it defines three kinds of hand over mechanism: hard handover, macro diversity handover (MDHO) and fast BS switching (FBSS) In this paper we have simulated the hard hand over mechanism of IEEE 802.16j transparent mode networks using NCTUns Tool. We have used Adaptive modulation and coding scheme. The results show when the mobile station moves form base station 1 (BS1) to base station 2(BS2), it has to disconnect the original connection with BS1 before making a new connection with BS2. And also it shows that the throughput gradually decrease when the mobile station moves to NLOS.

“…The concept of vertical handover insure the quality by reduction in effects know by Ping-Pong, to reduce interruption in process call at the time of handover, enhance the system throughput [7]. Several algorithms are based on method of classical network technique [8] and some of them are based on Markova outcomes process [9]. The important parameters are following; these are examined in vertical handoff decision for the proposed scheme to develop.…”

Keywords. Vertical handoff, Heterogeneous wireless mobile networks, new call blocking probability 1. Introduction. As we are moving towards expeditious development and rapid evolution in wireless networks, we faced different type of challenges i-e combining a diverse number of networks. The fourth generation (4G) of mobile communication networks is expected to integrate a possibly huge amount of heterogeneous wireless network in that could be investigated towards the universal seamless access. there will be many challenges in the process of seamless mobility one of the main is efficient vertical scheme availability, that is decision for a mobile point (i.e. mobile cell phone, tab-pc, Laptop) to handover among the various types of networks i.e, cellular, wireless area network (WAN, wide local area network (WLAN) [1]. As we look back to the traditional cellular approach to the communication which also mention with name GSM, the predefine threshold which compare different parameters in specific order is basically used to handle handover decisions [2] the handover are not only cause of ongoing call connections but it can be helpful in order to provide best services package and to fulfill their requirements for stable communication with the comparison to horizontal handover the newly presented vertical handover not only based on the received signal gain which is known as RSS but also the different services i-e class mapping among the handoff-out and handoff-out networks [3] high data rate services (HDS) and Nonpareil global roaming (NGR) eminent fourth generation 4G from the previous of wireless networks (WN) [4], [5].the 4g networking model contains, mobile nodes or handsets terminals connects by different multiple interfaces which will be able to select the best suitable link for access among the all available alternatives. Those ace links consist of IEEE 802.11 access of wireless local area network (WAN) [6]. When we talking about the idea behind connectivity in best way through various networks, a good QoS and also decrease in the call dropping level after unnecessary and wrong handover a phone call in process might be drop or interrupted. The wrong decision of handover cause by unnecessary handover directly affects the QoS makes interruption with ongoing transmission. The more important is the process of handover accurately and seamlessly executes to enhance the QoS. The application of multimedia i-e video streaming, web browsing depend upon good QoS the mandatory is to identify the
