Dynamic topologies and constrained recourses are two main characters of satellite networks. These characters require a specialized and efficient routing algorithm. In this paper, a QoS routing algorithm based on PEC multi objective optimization method is proposed to find paths that satisfy all user QoS requirements efficiently. A new routing scheme is also developed to reduce the computing load in...
Due to the recent developments in wireless technology and electronics, it is feasible to develop pervasive algorithms for satellite environments. Multi-Layered Satellite Networks (MLSNs) that consist of low earth orbit and medium earth orbit satellites are becoming increasingly important since they have higher coverage and better service than single-layered satellite networks. One of the challenges...
In the paper, the existing colony algorithm is improved for the routing computation of satellite networks with rapidly-changed network topology. A virtual topology strategy with new grouping is first proposed to deal with the problem of the rapidly-changed network topology, and then the improved ant colony algorithm is applied in routing optimization of satellite networks. Finally, the good performance...
