Private road supply in networks with heterogeneous users

Supporting Nomadic Users within Virtual Private Networks

Virtual Private Networks (VPNs) are communication environments for groups deployed within a public network but are actually not taking care of mobility. Nomadic VPN users have special requirements relating to resource adaptation and customization. This paper discusses how mobile agent technology applied to DPE-based VPN provides seamless access, service capabilities to nomadic users within the ...

Opportunistic Splitting Algorithms For Wireless Networks With Heterogeneous Users

In this paper, we develop medium access control protocols to enable users in a wireless network to opportunistically transmit when they have favorable channel conditions, without requiring a centralized scheduler. We consider approaches that use splitting algorithms to resolve collisions over a sequence of mini-slots to determine which user will transmit. We consider an asymmetric model where d...

Resource Management in Wireless Cellular Networks with Heterogeneous Capacity Supply and Heterogeneous Traffic Demand (HetHetNets)

The term HetNets (heterogeneous networks) is used to describe cellular networks in which the capacity supply is heterogeneous due to the overlaid architecture of macrocells and small-cells. In this thesis we use the term HetHetNets to refer to cellular networks in which the traffic demand is also heterogeneous due to reasons such as user spatial clustering and diversified user traffic types, in...

Securing the communications in Private Heterogeneous Mobile Ad-hoc Networks

Mobile ad hoc networking has been a hot research topic for a decade or so, and many paradigms have been making use of it. One of these paradigms is the Personal Networks (PN). It is an emerging concept where the user’s personal devices form a virtual network which is secure and private, and reacts to changing environment and context intelligently. A fundamental property of the PN is that person...
