Mathematically evaluating network performance before implementing real networks is very important in design of mobile ad-hoc wireless network because we can save time and effort. In this paper, we propose mathematical models to analyze route availability which is the probability that there exists a routing path between arbitrary source node and destination(More)
In this paper, we propose a Stability-aware Cooperative Routing scheme for Reliable high-speed data transmission in Multi-rate mobile ad hoc wireless networks, called SCRRM, to provide high data transmission with stable and reliable routes. The main features and contributions of our proposed routing scheme are as follows: First, we use the cross-layer(More)
In this paper, we investigate the multi-hop connectivity in cognitive radio ad-hoc networks (CRAHNs). Specifically, we propose an algorithm to check the multi-hop connectivity of two arbitrary secondary nodes with random nodes' locations and primary nodes' active states as inputs. Then, we use statistical simulation approach with our proposed algorithm to(More)
