“…In the four classifications, we have the first case that reflects a better stability for the node in question and the latter which represents a poor stability of the studied node, intuitively the second is better than the third, because N in is greater than N out and secondly, even with N div >N con the diverging node stay in the coverage area of the studied node. We determine subsequently metric degree of stability that will calculate for each category the best stability node, we use in the formula (7) the coefficient γof flow defined in [23], we divide the coefficient of 4 intervals as shown in Table 1, and metric of stability degree of node i will be as follows:…”

The design of robust routing protocol schemes for MANETs is quite complex, due to the characteristics and structural constraints of this network. A numerous variety of protocol schemes have been proposed in literature. Most of them are based on traditional method of routing, which doesn’t guarantee basic levels of Qos, when the network becomes larger, denser and dynamic. To solve this problem we use one of the most popular methods named clustering. In this work we try to improve the Qos in MANETs. We propose an algorithm of clustering based in the new mobility metric and K-Means method to distribute the nodes into several clusters; it is implemented to standard OLSR protocol giving birth a new protocol named OLSR Kmeans-SDE. The simulations showed that the results obtained by OLSR Kmeans-SDE exceed those obtained by standard OLSR Kmeans and OLSR Kmed+ in terms of, traffic Control, delay and packet delivery ratio.
