The Smart Home is based on the Wireless Sensor Network (WSN) and Embedded System (ES). The most important parts of the Smart Home are low-power and high-security. And it is very vulnerable to various attacks ether an active or passive one in WSN. We shed light upon some existing security flaws in W2 and ZigBee. Some are quite useful to defend the various attacks, but don't suit for the Smart Home...
Combined with the application of wireless sensor networks(WSN) for smart grid, this paper constructs the energy model of WSN, analyzing the principle and implementation method of Low Energy Adaptive Clustering Hierarchy(LEACH) algorithm. In consideration of characteristics of power communication, this paper pointed out weakness of the LEACH algorithm and proposed another improved SG-LEACH algorithm,...
