Link availability for any time in mobile ad hoc networks
Jianer Chen · Journal of Circuits and Systems · 2009
The metric for routing selection in terms of path availability which is based on link availability can be used to select reliable paths.Based on the random walk-based mobility model,we propose a prediction method for calculating the link availability of any time(LA(t)) on the basis of the duration T during which two nodes keep their movement status unchanged for the first time.Meanwhile,a general method which can calculate the average LET for a given model is developed as well as the general expression of LA(t) is given.A large number of simulation experiments based on various parameters demonstrate that the result of our method is more approximate to the practical result as compared with those of other methods.
