Vehicular communication is an important part of the Intelligent Transportation systems (ITS). Geographic routing in vehicular ad hoc network (VANET) is becoming an interesting topic to deliver safety messages between cars but also between a car and a roadside infrastructure within a designated destination area. the Car2Car Communication Consortium specified C2CNet architecture as a geographic routing protocol. the results of GeoNet project are presented in the paper, which aims at combining IPv6 networking and C2CNet. the system with IPv6 and C2CNet is designed and implemented in Linux. the prototype implementation is first evaluated indoor testbed withthe fixed positions. then it is evaluated in the field testbed withthree vehicles with various scenarios. For evaluation in field testbed, we have developed the AnaVANET evaluation tool to perform the evaluation taking into account all of geographic factors.

In this paper we present an approach that is capable to automatically generate semantic tagnets for given sets of german tags (keywords) and an arbitrary text corpus using three different analysis methods. the resulting tagnets are used to estimate similarities between texts that are manually tagged withthe keywords from the given tagset. Basically, this approach can be used in digital libraries to provide an efficient and intuitive interface for literature research. Although it is mainly optimized for the german language the proposed methods can easily be enhanced to generate tagnets for a given set of english keywords.

Device-to-device (D2D) communication as an underlaying cellular network empowers user-driven rich multimedia applications and also has proven to be network efficient offloading eNodeB traffic. However, D2D transmitters may cause significant amount of interference to the primary cellular network when radio resources are shared between them. During the downlink (DL) phase, primary cell UE (user equipment) may suffer from interference by the D2D transmitter. On the other hand, the immobile eNodeB is the victim of interference by the D2D transmitter during the uplink (UL) phase when radio resources are allocated randomly. Such interference can be avoided otherwise diminish if radio resource allocated intelligently withthe coordination from the eNodeB. In this paper, we formulate the problem of radio resource allocation to the D2D communications as a mixed integer nonlinear programming (MINLP). Such an optimization problem is notoriously hard to solve within fast scheduling period of the Long Term Evolution (LTE) network. We therefore propose an alternative greedy heuristic algorithm that can lessen interference to the primary cellular network utilizing channel gain information. We also perform extensive simulation to prove the efficacy of the proposed algorithm.

Proxy Mobile IPv6 (PMIPv6) supports multi-homing where a mobile node can connect to a PMIPv6 domain through multiple interfaces for simultaneous access. However, for an interface handoff, PMIPv6 does not allow simultaneous access since all the home network prefixes associated with one interface are associated with another interface of a MN. In this paper, we propose a dynamic home network prefixassignment (DHNPA) scheme where boththe fixed prefix model and shared prefix model are used for simultaneous access. Simulation results show that the DHNPA scheme can achieve simultaneous access and provide the information for handoff indication in multi-homing scenario. Copyright 2010 ACM.
