摘要: | 随建即连的网路是由一群行动主机自我组织起来的网路,和传统的移动无线网路不同的地方在于随建即连的网路不需要依靠一些固定的基础设施,例如基地台(Base station)以及接取点(Access point),他们的通讯方式是藉由中间节点的转送,以多点跳跃(multi-hop)的方式来完成,由于不受那些基础设施的限制,所以移动性高,而且部署非常容易。由于这些主机会一直移动,造成整个网路的拓朴不断的改变,所以必须要有一种快速的方法来侦测目前的拓朴(topology)情况,当使用中的路径中断时,才能够迅速的寻找到另外一条路径来继续传送。在无线网路中,安全性是一个很重要的关键,由于在一个无线的环境下传送资料是非常不可靠的,所以安全性也必须要考虑进去。我们研究了许多种路由的方法以及增加安全性的方法,由于我们的目标是希望整个方法是能够迅速以及简单,所以我们提出了一个方法,使得寻找路径加上增加安全性能够用一个简单的方法来实现。 An ad hoc network is a network composed by a group of mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure such as base stations and access points. These mobile hosts complete their transmission by transferring the data by intermediate nodes and send the data by multi-hop. Because ad hoc networks do not limit to the infrastructure, they have high mobility and they can be built easily. Because these hosts move, the topology of the network will always change. We have to use an algorithm to detect the topology fast. When some links are broken, we can find another path to keep transmitting the data as fast as possible. In wireless networks, security is a very important issue. Data transmission is vulnerable in the wireless surrounding, so we have to consider the security. There are many proposed routing methods and many ways to enhance the security. Because our goal is how to find another route to keep transmission when some links are broken and enhance the security easily, our proposed algorithm which combines the redundancy base multi-path routing protocol and the Diffie-Hellman key exchange algorithm can achieve our goal. |
