Wanghui Zeng, Wenjun Zong, Chaosong Xiong · 2012
In this paper, we achieve the optimization of UWB invisible network through modeling approach. We establish a random topology network, obtain the optimal routing of source - destination node through redefined 'shortest path algorithm'. We consider the interference among the nodes and the throughput of the entire network and determine the best shielding radius of each receiving node in the shield radius, that is, the node within the shielding radius is not allowed to be sent in accepting period. According to determined flow routing and shielding radius of the receiving node, we utilize the greedy algorithm to find the optimal scheduling. Finally, according to the results obtained above, we obtain the time slot of the weight and flow rate as well as the solution of utility function via the linear optimization method. Some of the factors in the model are analyzed through horizontal comparison and longitudinal comparison. If necessary, some mathematical derivation should be carried out. From the above, we reach some conclusions for the development of UWB network communication protocol.
