In this paper we study the routing security issues of MANETs, we propose an algorithm to detect malicious nodes based on intelligent water drops algorithm and examine "routing modification attack" problem that can easily be exploited against the MANETs. We also propose a solution for this problem and examine security issues related to proactive routing(More)
In this paper a new algorithm has been developed to enhance spatial structure by using texture feature extraction. Then, this algorithm has been programmed and an integrated program has been prepared by using Microsoft Visual C++ 6.0. In order to ascertain the usefulness of this algorithm, it has been applied in two groups of images, the first group(More)
