Research and Analysis of Slot Allocation Strategy for Hybrid Resource Scheduling in Wireless Multi-hop Cooperative Networks

Multi-hop,hybrid scheduling,slot allocation

In order to expand the scale of wireless multi-hop cooperative network, improve the network fault tolerance and reduce the delay of network establishment, we can combine the centralized and distributed mode to network. When the network scale is small, in order to reduce the scheduling delay, we can use distributed mode. When the network scale is big, in order to improve the stability of the system, we can use centralized mode. Therefore, considering the time to network establishment and network access, the time of three-way handshake of distributed scheduling, and to establish routing of centralized scheduling£¬this paper discusses and studies the hybrid scheduling, combines with the advantages of distributed scheduling and centralized scheduling, propose the slot allocation scheme of hybrid scheduling, which makes up for each other in the adaptation problems, meet the maximum needs of the indicators.
