In recent years, on the researches in various routing protocols, applications to digital home wireless heterogeneous networks become more and more important. In this paper, we propose a routing protocol based on event-oriented applied for digital home wireless heterogeneous networks, and a knowledge discovery agent will dynamically maintain an n-bits map(More)
IPTV (Internet Protocol Television) is a very important field in the network development. Comparing to the traditional television, the IPTV combines the digital contents like media. The communication and the advertisement with the interaction serve into the emerging business model to provide the users to watch television service. Because the IPTV contains(More)
Sensor nodes are resource-constrained, such as low battery life, computation, bandwidth and memory, so traditional public key schemes are impractical in wireless sensor networks. In the previous schemes, symmetric cryptography is the most common method used in sensor nodes. How to distribute keys into every sensor node is an important issue in many(More)
A number of user authentication schemes have been proposed to provide roaming services in the global mobility network (GLOMONET). However, most of these schemes are based on an asymmetric cryptosystem, which has a higher computational cost. To achieve computational efficiency, Chang et al. proposed an authentication scheme using simple hash functions for(More)
