Research On Resource Scheduling Alogorithms For Wireless Distributed Networks

Wireless distributed network has been developing rapidly in the wireless communication field in recent years. The advatanges of wireless distributed network provide this emerging technology with promising prospect. Especially with the rapid pace of the development of mobile internet and internet of things, wireless distributed network has attracted more and more research interests from both academic and industrial areas.However, because of its unique network characteristics, wireless distributed network also has some difficult problems to be sloved, including efficient and effective transmission scheduling, energy control strategy, appropriate routing algorithms, etc. These problems will prevent the further development and applications of wireless distributed network.In this paper, an in-depth research on these problems is conducted to explore optimal solutions. This paper mainly focuses on problems from two aspects:transmission control and energy scheduling. The problems have been divided into three parts, including non-confilciting transmission scheduling, energy limited based transmission scheduling, and energy harvesting based transmission control. To solve the first part, a graph coloring based transmission scheduling algorithm is proposed. The transmissions of the nodes in the network will be scheduled according to their colors to achieve no collisons. To solve the second part, an energy-aware transmission scheduling algorithm is proposed to prolong the network lifetime, as well as achieve short latency, low network load, etc. In the third part, a duty-cycle based dynamic transmission control algorithm is proposed. In this algorithm, the node’s duty-cycle will be dynamically controlled based on its energy harvesting potentiality and energy consumption. In this research, simulations of these proposed algorithms are also conducted to evaluate their performances. The results indicate that compared with other existing scheduling methods, these proposed algorithms can achieve better network performances and improve the quality of service provided by the network.
