k-DAG Based Lifetime Aware Data Collection in Wireless Sensor Networks [PDF]
International Journal of Wireless & Mobile Networks (IJWMN) Vol.
5, No. 5, October 2013, pp.17-33, 2013 Wireless Sensor Networks need to be organized for efficient data collection and lifetime maximization. In this paper, we propose a novel routing structure, namely k-DAG, to balance the load of the base station's neighbours while providing the worst-case latency guarantee for data collection, and a distributed algorithm for construction a k-DAG based on

A Multifunctional Binder for Current‐Collector‐Free Zn Powder Anodes
Advanced Materials, EarlyView.By introducing abundant polar groups as Zn2+ absorption sites and hydrogen bond arrays, a protein structure‐derived binder for ZP anode and iodine cathode is proposed. This design can regulate the Zn2+ flux, benefit the formation of free‐standing electrode, inhibit the side reactions, suppress the shuttle effect of polyiodides, and enable the large ...
