Simulation Results

Aircraft communication and satellite link handoff issues in spatial information network are very important and are focused in this paper. The simulation modules of satellite network nodes and links in network simulator version 2(NS-2) are analyzed in details in this paper. A method of extending NS-2 kernel module is proposed based on analysis of satellite network simulation principle and approach. As an example, the aircraft communication simulation module is designed and implemented. Simulation results show that flight of aircraft has effect on the link handoff characteristic, and show that the proposed extension method is feasible.

The Internet Of Things

The geostationary (GEO) satellite networks have two important influencing factors: high latency and transmission errors. Similarly, they will happen in the large-scale multihop network of the Internet of things (IoT), which will affect the application of 5G- (5th-generation mobile networks-) IoT. In this paper, we propose an enhanced TCP mechanism that increases the amount of data transferred in the slow start phase of TCP Hybla to mitigate the effect of long RTT and incorporates a refined mechanism of TCP Veno, which can distinguish packet loss between random and congestion. This scheme is evaluated and compared with NewReno, Hybla, and Veno by simulation, and the performance improvement of the proposed TCP scheme for GEO satellite network in the presence of random packet losses is demonstrated. At the same time, the enhanced TCP scheme can improve the transmission performance in the future 5G-IoT heterogeneous network with high delay and transmission .
