13 Apr 2008TL;DR: This work considers wireless mesh networks, and exploits the inherent broadcast nature of wireless by making use of multipath routing, and presents an optimization framework that enables it to derive optimal flow control, routing, scheduling, and rate adaptation schemes.
Abstract: We consider wireless mesh networks, and exploit the inherent broadcast nature of wireless by making use of multipath routing. We present an optimization framework that enables us to derive optimal flow control, routing, scheduling, and rate adaptation schemes, where we use network coding to ease the routing problem. We prove optimality and derive a primal-dual algorithm that lays the basis for a practical protocol. We use simulation to show on realistic topologies that we can achieve 20-200% throughput improvement compared to single path routing, and several times compared to a recent related opportunistic protocol (MORE).

TL;DR: A novel routing protocol named Game theory based Energy Efficient Clustering routing protocol (GEEC) is proposed, which belongs to a kind of clustering routing protocols, adopts evolutionary game theory mechanism to achieve energy exhaust equilibrium as well as lifetime extension at the same time.
Abstract: The energy constraint is one of the inherent defects of the Wireless Sensor Networks (WSNs). How to prolong the lifespan of the network has attracted more and more attention. Numerous achievements have emerged successively recently. Among these mechanisms designing routing protocols is one of the most promising ones owing to the large amount of energy consumed for data transmission. The background and related works are described firstly in detail in this paper. Then a game model for selecting the Cluster Head is presented. Subsequently, a novel routing protocol named Game theory based Energy Efficient Clustering routing protocol (GEEC) is proposed. GEEC, which belongs to a kind of clustering routing protocols, adopts evolutionary game theory mechanism to achieve energy exhaust equilibrium as well as lifetime extension at the same time. Finally, extensive simulation experiments are conducted. The experimental results indicate that a significant improvement in energy balance as well as in energy conservation compared with other two kinds of well-known clustering routing protocols is achieved.

08 Dec 2011TL;DR: Simulation results show that the improved AODV routing protocol in VANET can get better performances in forms of link stability and packet delivery ratio and two steps optimization in route discovery and route selection process to improve the route stability and decrease overhead.
Abstract: The rise in the number of vehicles has led to a rapid increasing need for vehicle communication today. The emerging Vehicular Ad Hoc Network (VANET) is becoming more and more important, which can provide intelligent transportation application, comfort application and other services for people in vehicles. In order to provide stable routes and obtain good performance in VANET, proper routing protocols must be designed. At present, some kinds of routing protocol have been used in VANET. As one of the most important routing protocols used in Mobile Ad Hoc Networks (MANET), AODV routing protocol is also used in VANET, and is often evaluated with other kinds of protocols. However, due to the different characteristics of the two networks, AODV protocol suffers poor performances when it is applied in VANET directly. So in our improved AODV routing protocol in VANET, we make two steps optimization in route discovery and route selection process to improve the route stability and decrease overhead. Simulation results show that our proposed AODV protocol can get better performances in forms of link stability and packet delivery ratio.

01 Oct 2006TL;DR: The opportunistic routing in dynamic ad hoc networks, the OPRAH protocols, which uses the air interface to find a more optimal path for each packet in a dynamic network.
Abstract: This paper describes the opportunistic routing in dynamic ad hoc networks, the OPRAH protocols, which uses the air interface to find a more optimal path for each packet in a dynamic network In the static environment the connectivity is perturbed only by fading between two fixed points, the performance of these protocols depends on how steady a route is Thus these protocols have the following advantages: ability to interoperate with wired protocols, to ensure that the ad hoc network can communicate with the legacy wired infrastructure, it works in a low mobility environment, and it should be implemented using relatively simple off-the-shelf components
