OLSR (Optimized Link State Routing) protocol is a priori Routing applied in MANET network. All nodes the network have information to other locally and need send large number of control messages maintain topology whole In UAV application scenarios, with increase node density, overhead will be too high problems hidden terminals intensified. Secondly, due fast moving speed UAVs, when neighboring U...

Composite adaptive radial basis function neural network (RBFNN) control with a lattice distribution of hidden nodes has three inherent demerits: 1) the approximation domain RBFNNs is difficult to be determined a priori ; 2) only partial persistence excitation (PE) condition can guaranteed; 3) i...

Outlier detection has many important applications in the field of fraud detection, network robustness analysis and intrusion detection. Some researches have utilized the neural network to solve the problem because it has the advantage of powerful modeling ability. In this paper, we propose a RBF neural network model using subtractive clustering algorithm for selecting the hidden node centers, w...

Recent studies have shown that cyberbullying is a rising youth epidemic. In this paper, we develop novel automated classification model identifies the texts without fitting them into large dimensional space. On other hand, classifier .cannot provide limited convergent solution due to its overfitting problem. Considering such limitations, developed text engine initially pre-processes tweets, eli...

We extend the well-studied concept of a graph power to that of a k-leaf power G of a tree T : G is formed by creating a node for each leaf in the tree and an edge between a pair of nodes if and only if the associated leaves are connected by a path of length at most k. By discovering hidden combinatorial structure of cliques and neighborhoods, we have developed polynomial-time algorithms that, f...

IEEE 802.11 is a standard for mobile ad hoc networks (MANET), implemented with various different protocols. Destination-Sequenced Distance-Vector Routing (DSDV) is one of the several protocols of IEEE 802.11 intended to provide various Quality of Service (QOS) parameters under acceptable range. To avoid the collision and interference the MAC protocol has only two solutions, one, to sense the ph...

We consider the rendezvous problem faced by two mobile agents, initially placed according to a known distribution on intersections in Manhatten (nodes of the integer lattice Z): We assume they can distinguish streets from avenues (the two axes) but have no common notion of North or East (positive directions along axes). How should they move, from node to adjacent node, so as to minimize the exp...

Mobile ad-hoc networks (MANETs) have no fixed infrastructure, so all network operations such as routing and packet forwarding are done by the nodes themselves. However, almost all common existing routing protocols basically focus on performance measures regardless of security issues. Since these protocols consider all nodes to be trustworthy, they are prone to serious security threats. Wormhole...
