“…Another flexible and scalable network selection scheme for multi-service heterogeneous wireless networks has been proposed in [4] in which, the profiles were created for users to symbolize their characteristics in terms of traffic status, mobility and QoS and the best cell was determined for each user by profile matching. In order to satisfy the individual requirements of every single user, authors of [5] addressed the network selection problem by taking into consideration a new user preference oriented network selection algorithm (UPNS) by combining entropy theory and fuzzy analytic hierarchy process algorithm (FAHP). In [6] authors have presented the design of a tool for network selection procedure within heterogeneous wireless network environments.…”

In wireless communication, new radio access technologies are emerging, capable of supporting larger coverage area and faster data rates. In a wireless heterogeneous environment consisting of disparate radio access technologies, selection of the best network is an important research issue. In this paper, we propose a novel network selection algorithm for a heterogeneous environment consisting of WiMAX and LTE standard. The proposed algorithm is based on received signal strength, signal to noise ratio, available bit rate, achievable throughput and bit error rate. Relative weights of the decision making attributes are optimized by employing particle swarm optimization approach. The number of satisfied users calculated (as per their demand with wireless network selected) by proposed algorithm is optimized by modified PSO and confirmed by Monte Carlo method. From the simulation results it is inferred that the number satisfied users while running multimedia applications has been improved by 50 % as compared to the existing network selection algorithms.

The Long Term Evolution (LTE) has been proposed for supporting higher bandwidth applications and large amount of users by installing many base stations known as eNodeBs. However, in an area, users may associate with some particular eNodeBs which may cause the unbalanced load distribution. In this paper, a heuristic load balance algorithm called Ripple Algorithm has been proposed. The algorithm is designed as a distributed algorithm without global knowledge assumption. The results show that the algorithm can perform well in many testing scenarios with low complexity.

“…A novel user preference oriented network selection algorithm (UPNS) was proposed, by combining entropy theory and fuzzy analytic hierarchy process algorithm (FAHP) with service level agreement (SLA) management model [4]. In [5], an effective access network selection algorithm for heterogeneous wireless networks was proposed that combines two Multi Attribute Decision Making (MADM) methods, the Analytic Hierarchy Process (AHP) method and the Total Order Preference by Similarity to the Ideal Solution (TOPSIS) method.…”

ABSTRACT:Always best connected services (ABC) allow multimode mobile terminals to stay connected to the best available networks, at anytime according to user preferences. One of the key aspects in realizing such ABC service is mainly attributed to an effective and dynamic access network selection process. However, most of the previous works consider the access network selection process as a static optimization problem which fails to address the dynamic QoS conditions intrinsic in wireless networks. One of the main challenges remaining is to find an efficient way of obtaining dynamic QoS parameters such as available bandwidth. In this paper, propose a novel dynamic access network selection algorithm capable of adapting to prevailing network conditions. Proposed algorithm is an estimation process where network selection in heterogeneous wireless environment (WiMAX & WLAN) performed using available bandwidth estimation relies on dynamic parameters designed using .net.
