In this paper we describe an approach to respond to a request for information with the identification and location of the appropriate person as a source of information for answering the question. The expertise of a person is characterized using a weighted profile that has been derived from a series of documents describing the expert's activities. Having these profiles, requests for information can be matched with these profiles. The best matches correspond with the people that are experts for providing information on the request.

In some distributed models information can be disappears in one place and other place. In reality there are no miracles. A message goes from one network to another; it can be lost or corrupted in the process. Here, we present a realistic but high-level communication model where communicators represent various wireless and wired network. The model was originally developed in the process of specifying particular network architecture. The purpose of the abstract communication model is not to design a new kind of network; rather, it is to discover the common part of all message-based communication networks. The generality of the model has been confirmed by its successful reuse for very different distributed architectures. Wired Communication Network can increasing amount of information in different areas it is important that security be considered in every phase of network design and maintenance and wireless Communication Network there is an endless quest for increased capacity and improved maintenance.

Just as terrestrial networks have shifted to routed, message centric networks, the satellite networking regime is beginning to transition in the same manner. Based on established networking theories and unique orbital models, a satellite based communications network architecture is modeled that would fulfill the requirements of capacity, coverage and logistics for current and future military needs. Specifically, various satellite constellations and network characteristics are examined with a focus on how to enhance current methods of routing data in this environment. The authors explore how Social Networking theories can be applied to the routing decision making process in the space environment. Utilizing aspects of adaptation and the weak-tie relationship, an adaptive hybrid routing protocol model is proposed leveraging the predictability of orbital mechanics to increase performance and decrease network overhead.
In Chapter 3 we considered some of the typical structures that characterize social networks , and some of the typical processes that aect the formation of links in the network. Our discussion there focused primarily on the network as an object of study in itself, relatively independent of the broader world in which it exists. However, the contexts in which a social network is embedded will generally have significant eects on its structure, Each individual in a social network has a distinctive set of personal characteristics, and similarities and compatibilities among two people's characteristics can strongly influence whether a link forms between them. Each individual also engages in a set of behaviors and activities that can shape the formation of links within the network. These considerations suggest what we mean by a network's surrounding contexts: factors that exist outside the nodes and edges of a network, but which nonetheless aect how the network's structure evolves. In this chapter we consider how such eects operate, and what they imply about the structure of social networks. Among other observations, we will find that the surrounding contexts aecting a network's formation can, to some extent, be viewed in network terms as well — and by expanding the network to represent the contexts together with the individuals, we will see in fact that several dierent processes of network formation can be described in a common framework.
