Abstract
The time division multiple access (TDMA) is thought a better choice for mobile ad hoc networks, especially for sparse and dynamic airborne wireless networks, and its efficiency largely depends on the slot scheduling method. Fully taking the dynamic characteristics of the 3-dimensional airborne network into account, we proposed an adaptive slot assignment TDMA (ASA-TDMA) scheme. It allows for changeable traffic load of the nodes due to the network topology dynamics in sparse airborne ad hoc networks. Slot allocation is performed not only when nodes request for time slots to access, but also when real-time load level changes. The sharing algorithm realizes concurrent transmissions to achieve high slot utilization. Furthermore, our scheme can flexibly adjust the schedule strategy to deal with network emergencies such as node failures. Simulations are provided to validate the performance our approach, and the results show its advantages over some known methods.
