We investigate the scaling law of throughput capacity of hybrid networks with non-trivial node mobility. By non-trivial mobility, we mean it is strong enough to improve capacity. A general model with heterogeneous nodes and spatial inhomogeneities is adopted. We show in a network, whose physical extension grows at f(n), with n users and k base stations, the per-node capacity is ??(1/f(n)) + ??(k/n)...
Accounting is a key task in commercial networks. With the increasing number of IP-based services and mobility support, accounting needs to evolve towards an integrated, service-oriented accounting approach in a mobile environment. Therefore, this dissertation digest paper presents the Service-oriented Tailored Accounting Configuration (STACO) architecture that enables a service-oriented accounting...
Most of the MANET protocols are evaluated by simulation environments. The validation is meaningful when they use realistic mobility models. Once the nodes have been initially distributed, the mobility model dictates the movement of the nodes within the network. If this movement is unrealistic, the simulation results obtained may not correctly reflect the true performance of the protocols. The majority...
