Non-geostationary (NGEO) satellite networks have a series of advantages over terrestrial networks. However, traditional routing algorithms such as the Dijkstra's Shortest Path (DSP) algorithm always lead to some Inter-Satellite Links (ISLs) heavily loaded. To guarantee a better distribution of traffic among satellites, this paper proposes a Fuzzy Satellite Congestion Indicator (FSCI) to estimate congestion status among neighboring satellites. Indeed, a satellite notifies its neighboring satellites of its FSCI. When it is about to get congested, it requests its neighboring satellites to decrease their data forwarding rates by sending them a self status notification signaling message. In response, the neighboring satellites search for less congested paths according to Fuzzy Route Determination. The routing strategy discussed above is Fuzzy Satellite Routing(FSR). This routing algorithm avoids both congestion and packet drops at the satellite. It also ensures a better traffic distribution over the entire satellite constellation. The mechanism of multiple traffic classes is also discussed in FSR. The good performance of FSR, in terms of short end-to-end delay, higher throughput, and lower packet drops, is verified via a set of simulations using the Network Simulator 2 (NS2).

Summary The past few years have witnessed the prosperity in the mobile Internet. The increased traffic with diverse QoS requirements calls for a more capable and flexible infrastructure. The satellite systems with global coverage capability can be used as the backbone network to interconnect autonomous systems worldwide. In this context, routing data in the satellite networks is of great importance considering the integration of the satellite networks with the terrestrial Internet protocol networks. This paper provides a systematic routing design in the geostationary orbit/low earth orbit (LEO) hybrid satellite networks. We first give the description of the architecture of the geostationary orbit/LEO satellite networks based on which the user mobility management mechanism is proposed. The core idea of the user mobility management mechanism lies in the division of the earth surface, which results in the separation of the user and the satellite segment along with the separation of the user identifier and locator. We then give an analysis of the division of the earth surface. Based on the separation of the user and the satellite segment, the hop‐constrained adaptive routing mechanism with load balancing capability is proposed. The simulations on an Iridium‐like LEO satellite network further document and confirm the positive characteristics of the proposed routing mechanism. Copyright © 2016 John Wiley & Sons, Ltd.

“…The underlying idea is to minimize the path similarity without introducing any extra control messages, and thus reduce the probability of eavesdropping consecutive packets over a specific link. A recent work in [15] designed a so-called intelligent routing strategy based on traffic lights (the congestion status). The idea supporting this work is that a packet may adjust the route dynamically according to the real-time color of traffic lights at each intermediate node, that is, a combination of preliminary planning and real-time adjustment.…”
