Abstract :
This paper presents a quantitative analysis by computer simulation of different handover algorithms for mobile satellite diversity based systems. The statistical but predefined nature of the constellation dynamics as well as the influence of the propagation channel in the handover mechanism enables the assessment of different levels of power and time hysteresis for different satellites within the network. Based on the above, two new handover algorithms are proposed for different modes of handover operation and compared with some known handover schemes by means of case studies in suburban environments for a LEO and a MEO satellite constellation
