In this case, the rejection of the null hypothesis would indicate that the market follows a random walk
hypothesis, and, consequently, that the market is weak-form efficient.
For Random Waypoint mobility model, and Random Walk
model has the smallest throughput value that obtained from the network when has 300 amounts of stations.
Although it is widely accepted that cell migration is complex and multifactorial, our results show that this process can be described with a modification of the random walk
model that also considers the application of external forces within a complex biological environment.

To perform a random walk
on a complex network, each node needs to calculate the transition probability from the node to each of its neighbors, but the knowledge available to this endpoint is limited to its local information.
Before the concept similarity is calculated by random walk
of a graph, it is needed to establish the initial distribution of the concept map.
By assuming that the covariance matrix presents time-dependent positions and the station monuments are subject to a random walk
process, then the formal uncertainty of the estimated velocities is approximated by (Zhang et al., 1997; Williams, 2003; Bos et al., 2008):
The Brownian model performed best at the shortest distances (< 7 cm); the correlated random walk
model overtook the Brownian model at 16.5 cm, and overtook the sea star model at 22.5 cm.
A random walk
algorithm is used to estimate the candidate confidence.
In addition, the data dissemination cost of the EDFC strategy is higher than the LTCDS strategy, although the length of each random walk
