Many recently built residential houses and factories are equipped with facilities for converting energy from green sources, such as solar energy, into electricity. Electricity consumers may input the extra electricity that they do not consume into the smart grid for sale, which is allowed by law in countries such as Japan. To reduce peak-time electricity usage, time-varying pricing schemes are usually...
This paper presents a new analytical model to analyze the performance of a probabilistic caching scheme with various cache replacement policies in content-centric networks. The cache replacement policies include Random Replacement (RR), First In First Out (FIFO), and Least Recently Used (LRU). This analytical model is based on Markov chains under Independent Reference Model (IRM) and Zero Download...
WiFi-Direct, a Wi-Fi standard, enables devices to connect easily with each other without requiring a wireless access point and communicate at typical WiFi speeds for file transfer, Internet connectivity, etc. It is widely used in many applications such as the traffic local sharing. The loss model of WiFi-direct link can facilitate the theoretical analysis when designing or optimizing the systems hence...
WWAN video multicast is challenging because of unavoidable packet losses, and inability to perform retransmission per packet for every user due to the NAK implosion problem. Previously proposed cooperative peer-to-peer repair (CPR) strategy, leveraging on the broadcast nature of wireless transmission and “uncorrelatedness” of receivers' channels, calls for peers with good WWAN channels to streaming...
