求帮翻译成中文 关于无线传感器网络的。

MyriaNed Basics
The MyriaNed WSN differs in some aspects to what is available today, like ZigBee Mica Motes and others. First of all it is based on gossiping. This is the main starting point and philosophy of MyriaNed. The ideas are researched at the Free University of Amsterdam (VU), by Prof. Maarten van Steen [Steen]. Today there is an extensive cooperation between his group and DevLab. Because the nature of gossiping news items in a WSN is so different from routing them in a“classic” way, we have developed our own Medium Access Controller (MAC), called gMac. The basic properties of this MAC is that it does broadcast transmissions of the news items. This implies that the MAClayer
doesn't need to have an ID or network address. However, there might be a need
to have an ID assigned to each individual node. This is implemented outside the MAC, mostly as part of the application. What is also important for a WSN application is that it is very energy efficient. Because the radio is the most energy consuming part of a WSN node, gMac has special properties that addresses this issue. gMac uses a Time Division Multiple Access (TDMA) message communication protocol with a very tight synchronisation mechanism between the nodes. The following sections will go into more detail on these issues.

Answer 1

与现有的如ZigBee Mica Motes或者其它WSN相比，MyriaNed无线传感器网络在有些方面有所不同。首先，它是基于随机转发（gossiping，也可以不翻译）的。这是MyriaNed的主要的出发点与核心思想。这个思路是阿姆斯特丹自由大学（Free University of Amsterdam ）的Maarten van Steen教授提出的，现在则开始与Devlab合作研究。由于随机转发的自然特性，使得WSN在路由方面与经典方式与众不同。我们已经开发出了自己的MAC协议，称为gMac。这种MAC协议的基本特性是广播传输，这就意味着MAC层不需要一个ID或网络地址。然而，给网络中的每个节点分配ID是有一定必要性的。当然这个工作在MAC层之外，一般在应用层中完成。对于一个WSN的应用而言，能源效率也是非常重要的。由于无线通信是WSN节点中能源消耗最多的一部分，因此gMac的一个特别属性是解决这个问题。gMac使用一种在节点之间严格同步的TDMA协议进行信息通信。接下来的章节将对上述问题进行更为详细的描述。
