An Improved Algorithm for Delay-Constrained Unicast Routing
In this paper, an improved delay-constrained unicast routing (I-DCUR) algorithm for real-time networks is studied, which is based on the delay-constrained unicast routing (DCUR) algorithm. The improved algorithm is quite different from DCUR algorithm when an active node detects a loop. The active node will firstly consider constructing a new path along the link between the active node and the previous node rather than firstly remove some links backwards the constructed path. Experimental results show that over 40% occurred loops are dealt with the improved algorithm for network size of 100 nodes, while over 60% for network size of 200 nodes. Also, simulations are made to compare the improved algorithm to the original DCUR algorithm on the path costs. Results show that I-DCURs path costs are less than those from DCUR about 9%.
