摘要

在manet中处理链路中断对路由协议来说是一个挑战。本文提出了一种机制来减少链路中断对路由的负面影响。节点的传输区域分为靠近节点的安全区和靠近传输范围末端的不安全区(即缓冲区)。位于缓冲区的相邻节点发生链路中断的概率较高,而位于安全区的相邻节点的链路则更稳定。因此,优先使用安全区域内的邻居作为中继节点,而缓冲区内的邻居仅在必要时使用,以避免网络分区。这种机制的主要代价是两个节点之间的平均跳数比没有这种机制时要高,但模拟表明,该解决方案提供了更高的吞吐量。

Routing with transmission buffer zones in MANETs
Dealing with link breaks in MANETs is a challenge for the routing protocol. This paper proposes a mechanism to reduce the negative impact of link breaks on the routing. The transmission area of a node is divided into a safe zone close to the node and an unsafe zone (i.e. buffer zone) near the end of the transmission range. The probability is high that link breaks occur with neighboring nodes located in the buffer zone, while links to neighboring nodes in the safe zone are expected to be more stable. Thus, neighbors in the safe zone are preferred as relay nodes, while neighbors in the buffer zone are only used if necessary to avoid network partitioning. The main cost of this mechanism is that the mean number of hops between two nodes is higher than without the mechanism, but simulations show that the solution offers increased throughput.
