“…Consider that the volume D of data packets needs to be routed from source s to destination d. if D is large; usually it is impossible to send data in a single path in a mobile environment. As our aim in this research is to have multipath routing in our network, we divide the total data volume D into comparatively smaller data volume packets D 1 , D 2 ,… called temporal data sets [3]. Since at this time we have only one available path, which had been constructed in reactive route setup, for keeping the network busy, the first temporal data set is going to be routed from s to d from that route.…”

Abstract-Mobile Ad hoc networks (MANET) are communication networks that consist of wireless nodes, which placed together in an ad hoc manner. Nodes can enter or leave the network at any time, so that the network topology changes frequently. In this paper we are going to propose an algorithm for routing in mobile ad hoc networks. Routing task has some challenging problem in MANETs, based on having dynamic and unplanned nature. For facing with these challenges we propose an Adaptive Multipath Ant Routing algorithm (AMAR) by combining ideas from artificial intelligence (AI) and multipath routing in this algorithm for improving the network performance. In an extensive set of simulation experiments, we compare this algorithm with AntHocNet and AODV and OLSR which are three reference algorithms in this research area.

“…In this paper we are going to propose an Adaptive Multipath Ant Routing algorithm (AMAR). This algorithm is based on a specific self-organizing behavior observed in ant colonies, the shortest paths discovery, and on the related optimization framework of Ant Colony Optimization (ACO) [2], with the use of multipath routing [3].…”

Abstract-One of the most important issues in Smart Grid is to provide consumers with the knowledge of their energy usage, as well as allowing the utility to monitor and control the electric system components with real time status. This would require the design of a network architecture that is capable of providing secure and reliable two-way communication from meters to other Smart Grid domains. While networking technologies and systems have been greatly enhanced, in wireless communication environments the smart grid faces new challenges in terms of reliability. In this paper we are mainly concerned with assessing the performance of wireless mesh networks for the last mile communication. We consider a tree-based mesh routing scheme based on a multigate mesh network architecture. The multigate mesh routing scheme is based on a flexible mesh network architecture that expands on the hybrid tree routing of the IEEE 802.11s. The network is specifically designed to operate in a multi gateway structure in order to meet the smart grid requirements in terms of reliability, self-healing, and throughput performance. To further exploit the multigate network structure, a timer-based multipath routing diversity scheme is proposed in order to enhance the network reliability. The network is then used to measure the performance in terms of throughput and reliability.

“…In [6], the authors proposed a multipath routing mechanism, which adaptively searches for available network paths from a source to a destination, and optimally routes traffic among the paths. However in [6], the routing problem was formulated as a static optimization problem, using the average value of some network parameters. On the contrary, we formulate the problem using a dynamic optimization framework, which is capable of reflecting the network dynamics.…”

Abstract-Maintaining performance and reliability in wireless networks is a challenging task due to the nature of wireless channels. Multipath data transmission has been used in wired scenarios to reduce latency, improve throughput, andwhen/where possible -balance the load. In this paper, we propose an approach for multipath data transmission over wireless networks. We demonstrate that the problem under study can be formulated as a Markov Decision Process (MDP) and we propose an algorithm called On-line Policy Iteration (OPI), to solve the formulated MDP in real time. We verified the proposed approach using simulations with ns-2 and data collected from real heterogeneous wired/wireless networks. The results indicate that we improve both delay and loss characteristics of end-to-end wireless communications outperforming the classical multi-path schemes including Round Robin and Join the Shortest Queue.
