By applying power usage statistics from smart meters, users are able to save energy in their homes or control smart appliances via home automation systems. However, owing to security and privacy concerns, it is recommended that smart meters (SM) should not have direct communication with smart appliances. In this paper, we propose a design for a smart meter gateway (SMGW) associated with a two-phase...
The resource of DTN (Delay Tolerant Network) is constrained and its links are unstable, so the states of network can't be fed back in time to the source node of data. The rate control mechanism and window mechanism of congestion control can't solve the congestion problem of DTN. The paper has proposed A DTN Congestion Control Mechanism Based on Distributed Storage (DCM). When the congestion of a DTN...
Delay tolerant network (DTN) is a network which implies asynchronous communication and does not require an end-to-end path at any point in time. Its main characteristic is the links between nodes are volatile and may break down for a long time at any time, so it can't be assumed that a path exists between the source node and the destination node. The current studies on DTN mainly use theoretical analysis,...
The smart home concept brings innovation and convenience to our every day's life style at home. Without context awareness, smart home applications cannot offer services that can adapt to users?? dynamic situations; they also fail to give preferential treatment for users?? various preferences. Such design paradigm forces human to live in the world of machines rather than a human oriented world. The...
