The most important issue in such environment is ABC (Always Best Connected) i.e. allowing the best connectivity to applications anywhere at any time. For always best connectivity requirement various vertical handover strategies for decision making have been proposed. This paper provides an overview of the most interesting and recent strategies.

In the next generation heterogeneous wireless networks it is desirable to consider the integration of various networks for providing the seamless connectivity to the mobile node roaming. The most important issue while providing the seamless connectivity is which network to choose from the given set of networks. During vertical handoff it is required to select the best network not only according to user preference but also the application, network and terminal contexts. The network selection algorithm plays a very important part in guaranteeing quality of service and seamless connectivity in such networks. This paper discuss the different network selection techniques available in the literature and explains a method for network selection which takes into consideration of multiple decision making criteria for selecting the optimal network.

While providing the seamless connectivity, a suitable network to choose from the given set of networks is the crucial issue. During vertical handoff, it is required to select the best network not only according to user preference but also the application, network and terminal contexts. The network selection algorithm plays a very important role in ensuring quality of service and seamless connectivity in such networks. Network selection in heterogeneous wireless networks has been widely studied by using various mathematical models, in which multiple attribute decision-making is one of the most popular models. This paper surveys the different network selection techniques available in the literature and explains a method for network selection which takes into consideration of multiple decision-making criteria for selecting the optimal network.

These systems need to provide browsing, querying, navigation, and, sometimes, composition capabilities involving various forms of media. In this survey, we review techniques for text, image, audio and video retrieval. We first look at indexing and retrieval techniques for text, audio, image and video. We also discuss features visual features for video retrieval such as colour, texture, shape. The indexing techniques are discussed for these features. We also compare most popular techniques used for indexing and retrieval.

The handover between these dissimilar networks can be explored by using vertical handover algorithms. This paper focuses on the vertical handover decision methods and algorithms effectiveness. Most of the algorithms which are based on RSS values provide vertical handover with small delay at a lower rate of throughput. There are such algorithms which provide significant improvements in throughput but at a cost of higher delays. As per the need for the real time applications in next generation wireless networks there is a requirement of developing new optimized algorithms that are able to produce high throughput and minimizing signalling cost and delay.
