Multi-Criteria Vertical Handover Comparison between Wimax and Wifi

Abstract

Abstract:In next generation wireless networks, the most tempting feature is the ability of the user to move smoothly over different access networks regardless of the network access technology. In this paper we study the benefit of Multiple Attribute Decision Making (MADM) strategies for network selection. We compare three of these methods naming Simple Additive Weighting (SAW), Multiplicative Exponential Weighting (MEW) and Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) in a realtime ns-3 simulation. Analytic Hierarchy Process (AHP) provides the weights of attributes which allow the comparison in different types of applications. Therefore, we propose a performance evaluation model with a reconfiguration of AHP parameters used in the literature. Simulation results show that the proposed parameters provide an improvement of Delay and offer allowable Packet loss in different types of applications.

A binary linear programming to the planning of wireless systems

“…In this situation, it is recommended to use an Analytic Hierarchy Process (AHP) as a methodology for defining the possible devices to acquire. An application of this is observable in [19].…”

A Network Selection Scheme Based on the Analytic Hierarchy Process for Marine Internet

“…Table 5 shows the values of such attributes. Some parameters are positive indicators [30][31][32][33][34], and the bigger the better, such as data transmission rate, network load, and accessibility probability; some parameters are negative, and the smaller the better, such as end-to-end delay, packet jitter, packet loss rate, and price; so, these parameters need to be normalized [35][36][37][38][39]. For positive parameters, the normalization formula is…”

Quality of experience and quality of service‐aware handover for video transmission in heterogeneous networks

“…17 Specifically, a QoS-aware algorithm for handover decision takes into account parameters related to network services, such as channel bandwidth, throughput, delay, and jitter. 14,21 Traditional Power Budget Algorithm (PBGT) 14 activates the handover execution when it detects a higher signal value in neighboring cells compared with the original cell. As a QoS requirement, this handover executes after taking into consideration both hysteresis (handover margin with value in decibel that the handover only executes if the target cell presents better signal strength than the serving cell plus this handover margin) and time-to-trigger (when an algorithm awaits a particular time to perform handover) 22 that are used to tackle unnecessary handover issues.…”

“…The AHP technique shows that its use provides a low complexity resolution and presents a good response. Drissi et al 21 also use AHP for a multicriteria handover, with only QoS parameters. Finally, Hussein et al 30 evaluate and solve an MCDM by applying fuzzy TOPSIS, considering criteria more focused on radio aspects, eg, signal strength and uplink signal-to-interference-plus-noise ratio.…”
