Although a standalone and isolated mobile ad hoc network (MANET) is practical in many scenarios, integration with the Internet is much more advantageous. The integration of a MANET with the Internet provides MANET users with Internet access and hence increases the scope of the MANET application. In addition, the Internet can benefit from this integration by an extension of the network coverage area. However, the integration of heterogeneous networks raises many issues. To overcome the incompatibilities between different architectures, gateways are used. This paper proposes a lightweight integration scheme for a MANET and the wider Internet, based on the optimized link state routing (OLSR). OLSR routing messages are reengineered and optimized to meet the needs of integration without involving additional routing messages for gateway discovery. The compulsory registration of a MANET node with a gateway node in a traditional integration is not required in the proposed approach, meaning that nodes can move freely within the local MANET with no disruption in the connection to another node in the external network. The proposed system is evaluated using the OMNET++ network simulator and is compared to another existing system. The simulation results demonstrate the validity of the proposed approach.

基于OLSR的移动Ad Hoc网络与Internet的集成。

尽管独立的隔离移动自组织网络（MANET）在许多情况下都是可行的，但与Internet集成更为有利。MANET与Internet的集成为MANET用户提供了Internet访问权限，因此扩大了MANET应用程序的范围。另外，通过扩展网络覆盖范围，Internet可以从这种集成中受益。但是，异构网络的集成提出了许多问题。为了克服不同体系结构之间的不兼容性，使用了网关。本文基于优化的链接状态路由（OLSR）提出了一种用于MANET和更广泛的Internet的轻量级集成方案。重新设计和优化了OLSR路由消息，以满足集成需求，而无需为网关发现添加其他路由消息。在所提出的方法中，不需要在传统集成中将MANET节点强制注册为网关节点，这意味着节点可以在本地MANET中自由移动，而不会中断与外部网络中另一个节点的连接。建议的系统使用OMNET ++网络模拟器进行评估，并与另一个现有系统进行比较。仿真结果证明了该方法的有效性。
