In a Mobile Ad hoc NETwork (MANET), nodes are self-organized and have to cooperate for routing in absence of fixed infrastructure. Two nodes beyond the direct communication range need intermediate nodes to forward their packets. Working in an open environment, MANETs are vulnerable to attacks by malicious nodes. A trust-based on-demand routing framework is given to decrease the hazards from malicious...
This study improves the original model of vehicle routing problem by adding some strains such as time windows, volume, weight, as parameters into the model. The model is adjusted to an mutilate-goals vehicle scheduling problem based on the mutilate-goals programming, and study on how the time-windows and time-distinction affects the delivering planning. We use GAMS to simulate and solve this problem.
In framework for integrating Internet and MANET, because the equipments in the networks are fixed, there is no need to consider the problem of energy. In MANET (mobile ad hoc network), the energy of the mobile nodes will affect the life time and the performance of the network, so it must consider the load and energy of a node. This paper proposes a new routing method called Load balancing and asymmetrical...
A fast rerouting scheme is proposed to guarantee the QoS performance of rerouted path when handling link and node failures. The new scheme is based on deflection routing mechanism and improves on two aspects: first, it can promptly handle single node failure as well as single link failure, second, QoS metric is taken into accounted when calculating recovery routes. Simulation results show that the...
It is essential for us to do research on collaboration mechanism in management-control plane in intelligent optical networks. We propose an interaction schemes using mobile agent between the control plane and management plane to solve information collection delay and management messages congestion. We construct the integrated platform by mobile agent.
Route flap caused by link flap in OSPF always lead to network instability and unreliability. Most of the prevailing solutions are network-wide and require all routers to participate in the route flap suppressing process, which not only lack flexibility and scalability but also occupy additional computation resources across the network. In this paper, a localized approach is proposed to suppress the...
Routes in an ad hoc network may fail frequently because of node mobility. Stability therefore can be an important element in the design of routing protocols. The node escape probability is introduced to estimate the lifetime and stability of link between neighboring nodes and the escape probability based routing (EPBR) scheme to discover stable routes is proposed. Simulation results show that the...
Since performance on FPGAs is dominated by the routing architecture rather than wire length, we propose a new architecture-aware approach to initial FPGA placement that models the relationship between performance and the routing grid, using concepts from graph embedding and metric geometry. Our approach, CAPRI, can be viewed as an embedding of a graph representing the net list into a metric space...
