简介：龙门堂墓地位于湖北省郧县东约60公里的安阳镇小河村一组的五谷庙岭,2010年11月至2012年6月,为配合南水北调中线工程建设,南开大学考古学与博物馆学系对该墓地进行了抢救性发掘。共发掘墓葬77座,现将其中M37与M56两座墓葬的发掘及出土情况进行详细介绍。两座墓葬均为带斜坡墓道的长方形砖室墓,共出土陶器、铜器、玉器和石器35件,钱币233枚。依据墓葬形制、器物组合等判断,M37时代约为西汉晚期至东汉早中期,M56时代约为新莽时期至东汉早中期。

简介：随着M2M的快速发展,基于蜂窝网路的M2M通信已经成为当前的主要移动通信方法,然而基于蜂窝网络的M2M的能耗问题是阻碍其迅速发展的一个瓶颈。为了降低网络的能耗和实现负载的均衡,提出一种低能耗的能量感知物联网M2M路由协议。在AODV网络协议的基础上,对路由发现的过程进行改进,在对下一跳节点的选择上充分考虑当前节点到下一跳节点的发送能耗和下一跳节点对当前节点发送数据的接收能耗,同时对网络链路的断裂进行重新修复。仿真实验结果表明：该低能耗的路由协议能适时感知链路质量,同时在选择路由时尽可能地降低路由总能耗,是一种M2M下的可行路由协议。
