Routing protocols in satellite networks

Routing protocols provide basic connectivity for the Internet. Routing is the action of nodes finding paths to deliver data packets. The mobile ad hoc network (MANET) is a self-configuring network, based on mobile nodes and wireless transmission. The nodes’ flexible position enables MANET’s application in various scenarios including satellite communication. While providing stronger robustness, the mobility of nodes in MANET also incurs negative effects such as disrupted links and limited route lifetime. Ad hoc On-demand Distance Vector (AODV) routing is a reactive routing protocol, in which routes are searched and established on request. In this project, AODV is studied and implemented in the satellite communication. Different parameters in the protocol are studied firstly in wireless sensor networks (WSN) simulation. By comparing the characteristics of conventional WSN and satellite communication, the parameters are adjusted to conclude the best setting for this scenario. We survey the performance of AODV in satellite communication using ns-3 simulation engine. Finally, we propose four solutions to handle the possible errors in the implementations of AODV
