	1	Dynamic Polling MAC Scheme Considering Emergency Access in WSNs Based on Priorities显示文摘In Wireless Sensor Networks(WSNs),polling can obviously improve the throughput and decrease average access delay by allocating bandwidth efficiently and reasonably.In this paper,a Dynamic Polling Media Access Control (DPMAC) scheme designed according to WSNs' features is proposed.DPMAC is a priority based access control protocol with the characteristics that its polling table is dynamically refreshed depending on whether the sensor node is active and that the bandwidth is dynamically allocated according to the traffic types.The access priorities are determined by the emergency levels of events and the scheduler proposed in our MAC is preemptive based on the deadline of the events.Simulation results show that DPMAC can efficiently utilize bandwidth and decrease average access delay and response time for emergency events with different access priorities in WSNs.

	2	Security Enhancement of Robust User Authentication Framework for Wireless Sensor Networks显示文摘In order to remedy the security weaknesses of a robust user authentication framework for wireless sensor networks, an enhanced user authentication framework is presented. The enhanced scheme requires proof of the possession of both a password and a smart card, and provides more security guarantees in two aspects: 1) it addresses the untraceability property so that any third party accessing the communication channel cannot link two authentication sessions originated from the same user, and 2) the use of a smart card prevents offline attacks to guess passwords. The security and efficiency analyses indicate that our enhanced scheme provides the highest level of security at reasonable computational costs. Therefore, it is a practical authentication scheme with attractive security features for wireless sensor networks.	Jiang Qi Ma Zhuo Ma Jianfeng Li Guangsong	2012	China Communications2012，9，10：	3
