A Cross Layered Approach for Network Selection in Heterogeneous Wireless Networks
نویسندگان
چکیده
Service delivery in a heterogeneous wireless network environment requires the selection of an optimal access network. Selection of a least favorable network can result in insufferable effects such as higher costs or poor service experience. Subsequently, network selection techniques play a vital role in ensuring Quality of Service (QoS) in heterogeneous networks. Network selection in such an environment is determined by several factors with different relative importance. The access network selection problem is usually looked at from the aspect of multi-criteria analysis. The proposed mechanism is based on a modified Multi Criteria Decision Making (MCDM) Scheme that assists the Mobile Subscriber Stations (MSSs) to dynamically select the top candidate network based on the QoS values. The performance analysis reveals that the proposed network selection scheme selects a better network and yields better results.
