Abstract
A satellite network’s multiple access protocol must be well designed to efficiently occupy channel resources and meet various qualities of service requirements. In this paper, a combined free/demand assignment multiple access protocol based on gray forecast is proposed. In terms of access, the adoption of the gray forecast method allows the user to book the number of timeslots to have more than the existing number of burst of packets. In terms of bandwidth allocation, a user priority allocation method is used to prioritize users with high needs and focus on the allocation of satellite resources. Experimental results show that the proposed protocol can effectively improve the channel utilization of the entire system. Thus, this protocol has some advantages over existing protocols in network throughput and end-to-end delay.
Highlights
Challenges posed by communication networks [1] are attributed to the rapid development of social informatization, the continuous expansion of network users, the constant improvement of service demand and the emergence of new services [2]
On the basis of the achievements and deficiencies of related work, we propose a combined free/demand assignment multiple access-gray forecast (CFDAMA-GF) protocol for satellite network access
In the CFDAMA-GF protocol, a forecast method is used in the access procedure so that the number of reservation slots currently sent by a user is greater than the number of packets in the current queue to ensure that the packet arriving at the moment can be sent in time without queuing
Summary
Challenges posed by communication networks [1] are attributed to the rapid development of social informatization, the continuous expansion of network users, the constant improvement of service demand and the emergence of new services [2]. The number of timeslots allocated to a user from a system with remaining timeslots is allocated according to the requirements These remaining timeslots are freely poll allocated to all active user terminals, and channel resource allocation is reasonable because these protocols have demand assignment and free allocation. Demand assignment distribution is the most commonly-used access method by the existing satellite networks This distribution can allocate demand assignments according to each user’s timeslot request so that the number of users can be changed regularly without wasting channel resources. The basic principle of CFDAMA is in accordance with a user’s reservation request for allocation, and remaining timeslots are freely poll assigned to all active user terminals [17]. These users’ requests become accumulated in the frame for processing
