Recently, there has been extraordinary propagation in the number of virtual teams for knowledge sharing; however, finding out what affects team member’s behavior is important. This paper integrates the Theory of Reasoned Action (TRA) and the Theory of Planned Behavior (TPB) to construct a model for investigating the socio-behavioral factors behind virtual knowledge sharing. The results of previ...

As sensor networks are deployed over various terrains, the complexity of their topology continues to grow. Voids in networks often cause existing geographic routing algorithms to fail. In this paper, we introduce a novel concept: virtual position to address this issue. A virtual position is the middle position of all direct neighbors of a node. Such virtual position reflects the neighborhood of...

This paper considers the problems of admission control and virtual circuit routing in high performance computing and communication systems. Admission control and virtual circuit routing problems arise in numerous applications, including video-servers, real-time database servers, and the provision of permanent virtual channels in large-scale communications networks. The paper describes both uppe...

We discuss challenges arising from using virtual coordinates for routing in ad hoc and sensor networks in multi-domain network scenarios. Recently, it has been shown that virtual coordinate based routing techniques are able to overcome several problems in ad hoc networks. They are independent of known geographic locations and less prone to routing failures. Additionally, some of the proposed so...

Multi-user virtual communities have become an accepted fundamental component of communication whereby community members share information and knowledge for mutual learning or problem solving. Virtual communities in a multi-user virtual environment (MUVE) have evolved into active social networks, formulating an alternative social existence and this phenomenon warrants further investigations. In ...

The Virtual Network Mapping Problem arises in the context of Future Internet research. The core idea is the introduction of virtual networks to the Internet to be able to improve its functionality in a non-disruptive way. This also enables the creation of specialized networks which directly provide functionality required by some application classes. The challenge of fitting all the virtual netw...

T h e routing techniques used in Conventional packet radio networks are n o t suitable for dynamic multihop wireless networks because of their unique architecture. In this paper, a n e w hierarchical multihop routing algorithm is introduced which balances the cost of locationupdate and path-finding operations by partitioning the terminals and mobile base stations t o produce a virtual topology....
