Abstract

Mobile ad-hoc networks (MANETs) are dynamic in nature. Links between nodes may constantly change due to mobility. The performance of the transmission control protocol (TCP) degrades in such an environment mainly due to its inability to differentiate between congestion and link failures which are frequent in MANETs. Several TCP variants were proposed to adapt TCP to a mobile environment. In addition, other reliable transport protocols were especially designed for MANETs as an alternative to these TCP variants. Several network settings might require different transport protocols to coexist and interoperate. In this paper we present a model that can be used to achieve interoperability between reliable transport protocols. The proposed model consists of forming an intermediate easy-to-implement thin layer between the network layer and the transport layer in the TCP/IP stack. Such layer will be invoked at the receiver side and will preserve the semantics of the sender's transport protocol. Our proposed model focuses on TCP and ATP, the ad-hoc transport protocols, but it can be expanded to accommodate other protocols.

移动自组织环境的传输层互操作性模型

移动自组网(manet)本质上是动态的。由于移动性，节点之间的链接可能不断变化。在这种环境下，传输控制协议(TCP)的性能下降主要是因为它无法区分拥塞和链路故障，而这在manet中是常见的。为了使TCP适应移动环境，提出了几种TCP变体。此外，其他可靠的传输协议是专门为manet设计的，作为这些TCP变体的替代方案。多个网络设置可能需要不同的传输协议共存和互操作。在本文中，我们提出了一个可用于实现可靠传输协议之间互操作性的模型。提出的模型包括在TCP/IP协议栈的网络层和传输层之间形成一个易于实现的中间薄层。该层将在接收端调用，并保留发送方传输协议的语义。我们提出的模型侧重于TCP和ATP，即自组织传输协议，但它可以扩展以适应其他协议。
