بخشی از مقاله انگلیسی: 1 Introduction In the routing protocol of Wireless mesh networks, the design of routing metric and algorithm must satisfy the dynamic requirements of operations on the multi-objective performance (such as delay, bandwidth, reduce congestion, reduce interference, and QoS guarantees). Cognitive Radio Networks (CRNs) are being studied intensively. Routing in CRN is a challenging task due the diversity in the available channels and data rates [1]. The quality of wireless links would be affected or even jeopardized by many factors like collisions, fading or the noise of environment [2]. A wireless MANET is a collection of wireless mobile hosts that dynamically create a temporary network without a fixed infrastructure. The topology of the network may change unpredictably and frequently [3]. High quality multimedia forensics service is increasingly critical for delay-sensitive applications over heterogeneous networks [4]. A class of Delay Tolerant Networks (DTN), which may violate one or more of the assumptions regarding the overall performance characteristics of the underlying links in order to achieve smooth operation, is rapidly growing in importance but may not be well served by the current end-to-end TCP/IP model [5]. a computational intelligence approach -a reinforcement learning algorithm (RLA)-for optimizing the routing in asynchronous transfer mode (ATM) networks based on the private network-to-network interface (PNNI) standard is proposed [6]. Energy Saving IP Routing (ESIR), to be applied in an IP network. ESIR operation is integrated with Open Shorthest Path First (OSPF) protocol and allows the selection of the links to be switched off so that the negative effects of the IP topology reconfiguration procedures are avoided [7]. Dataflow convergence on gateway nodes may cause load imbalance, thereby causing congestion, packet loss and buffer overflow. Breaking up existing routing strategies into a small number of common and tunable routing modules, and then show how and when a given routing module should be used, depending on the set of network characteristics exhibited by the wireless application [8]. The higher-layer nature of inter-domain routing requires reviewing the whole routing process in order to maximize performance at low decision making cost, a clear case for fuzzy set logic-based algorithms [9]. Quality of routing (QoR) games which always have Nash equilibria. Nash equilibria of QoR games give poly-log approximations to hard optimization problems [10]. The directional routing and scheduling scheme (DRSS) for green vehicle delay tolerant networks (DTNs) by using Nash Q-learning approach that can optimize the energy efficiency with the considerations of congestion, buffer and delay [11]. 2 Routing metric modeling 2.1 Problem proposed In the wireless Mesh network, load balancing is importance for efficient use of network capacity and improving network throughput. Network load imbalance will have the following main problems: (1) relay causes a decline of network capacity; (2) near the gateway area easily causes congestion; (3) the bottleneck node affects the entire network connectivity. Therefore, the network load balancing is a key factor to improve routing performance. Load balancing in Wireless Mesh networks differ from traditional wireless networks, the load balancing mechanism for wireless Ad hoc networks is suitable dynamic nodes. And the mechanism for wireless sensor network nodes are taken into account the capacity constraints of energy and computing. Relative to the relatively stable network topology and less mobile features in Wireless Mesh networks, the existing load balancing mechanism is not suitable, it is necessary to design an efficient load balancing algorithm to achieve optimal network performance for wireless Mesh network. In this paper, the ultimate goal is Solving a link load awareness routing metric and an adaptive dynamic load balancing on-demand routing algorithm, to maximize the channel utilization, balance the network traffic and achieve lower routing overhead. |
