y to keep pace with that. Lastly, the distribution and sharing of information is also problematic for the semantic technologies but still they are utilized for the sake of better knowing the mobility patterns of individuals [18].

Technological Infrastructure

Along with the above mentioned points, technological infrastructure also keeps its importance because it supports the services mentioned above and in case of using inappropriate infrastructure; there is a possibility of its not being able to support the desired task. There are two different points of views that can be used to illustrate how it can be judged which infrastructure is best suited for the task. First one involves the communication issues as for developing apprehending context-aware services. Help is taken from communication technologies. Their functionality is enclosed because almost all the systems distributed are, somehow, connected with each other. Not only the systems but the applications are also having interconnectivity in the course of devising the contextual computing environment.

 

As mentioned earlier that there are two different perspectives, one is discussed in the above paragraph whereas second one is of integration. Distribution is the challenge in the way of communication and demands technological support for the sake of developing integration at least at the level of software. This level includes the architecture of the software along with framework of development. Not only this but middle layers are also included in the software level that is used to develop integration. Modules are used to make the systems and also develop the operative relations and it is interesting to know that these modules are defined by the architecture models and acquire their general structure from the computing systems. These architectures are implemented by the frameworks giving room to those who are involved in development of software to improve the operations of those traits that are associated with contextual computing system. Furthermore, the framework is supported by the middle ware layer that serves as a linkage between three of the parts i.e., architecture, framework and technology especially the one involved in resolution of communication issues. Moreover, this linkage is also facilitated by the presence of this layer [18].

 

Moving towards Mobility Models

So, in other words the functioning of mobile wireless system may be assessed and enthused by the use of mobility models. It is important to measure because algorithms and protocols are also evaluated on the basis of that measurement. Every mobile environment is designed on the basis of diverse applications that are stimulated because of various aspects associated with that. This is why; it is very difficult to define the realistic mobility models as it is really critical to decide which model falls best in the category of mobility models.
