Unmanned Aerial Vehicles (UAVs) play more and more important roles in modern warfare. However, the data routing for communication among UAVs faces several challenges, such as packet loss or routing path failure etc. The main problem of UAVs data routing is caused by the high mobility of UAVs. In this paper, an effective geographic mobility prediction routing protocol is proposed to improve the performance...
In order to find a stable-aware way in view of load sharing and routing stability to split traffic load over multi-path, we develop a traffic assignment for multi-path routing in cognitive radio ad hoc networks in this paper. In the framework of game theory, the problem coincides with a n-person noncooperative differential game. We show that the feedback Nash equilibrium of the game is a stableaware...
We study the problem of computing multicast trees with minimal energy consumption in multi-hop wireless ad hoc networks. We demonstrate in this paper, that for two multicast trees having the same number of forwarding nodes in an ad hoc network, the one with least steiner nodes consumes least bandwidth. A greedy Label Based Greedy Algorithm (LBGA) is presented. Our algorithm LBGA with time complexity...
The existing data gathering scheme in wireless sensor networks usually takes place from sensors to static sinks. If sink can move randomly, data gathering process needs the cooperation of sinks. In this article, a load balancing data gathering scheme is proposed. In our scheme, the sensed data for target is stored in the storage path pointed to the network center, and the query request put forward...
The certification service technology based on threshold secret sharing mechanism in mobile ad-hoc networks is deeply analyzed. The distributed key generation algorithm based on ECDSA (Elliptic Curve Digital Signature Algorithm) is proposed, which generate the key and key share without assuming any trusted dealer, and improve the security of distributed certification in mobile Ad-hoc networks. The...
This paper considers an issue joint rate control and dynamic scheduling in mobile ad hoc networks. We propose a cross-layer rate control scheme that jointly computes both the rate allocation and dynamic scheduling. The scheduling in ad hoc networks is a difficult problem and in general NP-hard, or requires centralized implementation. In this paper, we present a dynamic approximation algorithm adapted...
This paper establishes a differential game model with coupling constraint for routing in ad hoc networks. We propose two definitions: coupling constraint equilibrium set (CCESet) and coupling constraint equilibrium solution (CCES), and design an iterative algorithm. The simulation results show the effect on the payoff values for different coupling constraint, and the effect on strategies for different...
