The node replica attack is known to be dangerous to wireless sensor networks (WSNs) because it enables the adversary to extend the damage throughout the network with very low cost. To stop such attack, we propose a similarity estimation based scheme with group deployment knowledge. Compared with prior works, our proposal provides extra functionality that prevent replica from generating false location...
In a multi-network environment, users can receive services via several networks, protocols, and connected devices. These services are usually bound to their specific technology and often limited to a dedicated service provider domain. We are developing a platform overcoming these limitations by enabling information sharing beyond the boundaries of network technologies and services. In this paper,...
Horizontal layered reference architecture of the third generation mobile network is presented in this paper. The work flow of location service is analyzed based on the architecture. The scenario of new location service mobility-ATM is described in it. Finally, an application of the service is designed and implemented to show how to develop 3G service in service layer of the architecture
