Satellite communication is regarded as a promising way to achieve seamless global coverage with an array of advantages over the traditional terrestrial network. However, the non-uniform distribution of users and the highly topological dynamics have been a matter of facts. The traditional load balancing technique is able to guarantee a better traffic distribution around the Inter Satellite Links with heavy loads after considering the non-uniform distribution of users, but it transmits load information passively and fails to provide a fair traffic distribution over the entire constellation. Given the highly topological dynamics, traditional routing protocols may experience the convergence processes frequently or use a large amount of storage to keep the snapshots. This paper proposes a novel routing protocol named LPR for the Satellite IP Networks, which transmits the bottleneck link load information to upstream satellites in a Hop-by-Hop manner actively, to guarantee a better distribution of traffic among satellites. In response, upstream satellites select less congested paths and communicate a portion of data according to the priority of different classes of traffic. In addition, LPR applies the geographical position when selecting the routing path to eliminate the convergence process which may cause the routing tables invalid. Finally, various aspects of performance of LPR have compared with other mechanisms. Our evaluations show that a routing protocol with load-aware and position-aided leads to higher throughput and better traffic distribution compared to the traditional routing protocol and load balancing technique.

“…A simple representative of a geographically dependent source/ destination distribution assumes homogeneous distribution over the landmasses, considering continents and major islands (called landmass distribution), while traffic intensity above the oceans equals 0 (Mohorcic et al, 2002b). More realistic source/destination distributions should reflect the geographic distribution of traffic intensity, which is related to several techno-economic factors including the population density and distribution, the existing telecommunication infrastructure, industrial development, service penetration and acceptance level, gross domestic product (GDP) in a given region, and pricing of services and terminals (Werner & Maral, 1997, Hu & Sheriff, 1997, Werner & Lutz 1998.…”

Abstract-In this paper, a location-assisted on-demand routing (LAOR) protocol for low earth orbit (LEO) satellite systems is proposed and evaluated. This protocol can be viewed as a variant of the well-known ad-hoc on-demand distance vector (AODV) routing protocol, tailored to the requirements imposed by the characteristics of LEO satellite systems' topology. The LAOR protocol is assessed for different link-cost metrics and compared to centralized routing protocols proposed in the literature thus far. Simulation studies further document and confirm the positive characteristics of the proposed protocol.
