Minimal Effort

Wireless Mesh Network (WMN) is a convincing theme to many net researchist because of its minimal effort in sending, straightforwardness in the establishment and heartiness in activity. Notwithstanding, current routing protocols intended for MANET, can't work productively in WMN on the grounds that spine in WMN shaped by Mesh Router has low portability and are not put under power and memory duress. In this paper, we are coming with a new idea of routing using geographic multipath, which will be beneficial for an Infrastructural WMNetwork and also don't depend on node's location. The proposed protocols has awareness, about the node's congestion and the node's location of all next neighbors, and utilize Hop-Count array technique. Furthermore, with help of a procedure of congestion-cognizant, nodes can select the perfect connection with adequate bandwidth for the requirement of comer traffic. In the proposed protocol for routing we accomplish various remarkable characteristics of Hop-count array (metric) depend on routing algorithm: straightforwardness, durability and feasibility of affectation. Results demonstrate that throughput increments extraordinarily with our proposed protocol when contrasted with unadulterated AODV and AOMDVin heavily loaded traffic situation.

Wireless mesh network (WMN) operates both in infrastructure and ad-hoc mode. It provides extended network coverage based on heterogeneous wireless technologies through multi-hop communications. In WMNs, the routing mechanisms and network organization need to be improved so that optimal path discovery or different protocols adaptability can be achieved. Hybrid routing is a demanding issue to be discussed these days as need of higher mobility management in the diverse situations and environments. It's required to improve the older schemes for higher data rate and minimum energy consumptions. The proposed work presents a design of a novel routing algorithm for optimal route discovery, congestion reduction, dynamic route selection and scalability in hybrid mesh networks. The authors have focused on Hybrid Routing Protocols to originate a novel routing scheme based on AODV (Ad hoc On-Demand Distance Vector routing protocol) in Ad-Hoc level with clustering scheme and DSDV (Destination Sequence Distance Vector) as proactive routing protocol in Backbone Mesh Router Level to form a new hybrid routing protocol. In this work a Novel Hybrid Distance Vector (NHDV) routing protocol algorithm has been introduced, which is the combination of DSDV (Destination Sequence Distance Vector) and AODV routing protocols. A clustering scheme with the combination of two efficient clustering schemes for Ad-hoc mesh client levels is discussed in detail and a performance metric for DSDV is also discussed which ETX (Expected Transmission Count) is for measuring packet loss ratio at each link for higher throughput. A new performance metric introduced in AODV as Mesh Router Count is used to improve the performance of communication to the Mesh Routers. The proposed work is the design of new algorithm that presents an optimal solution in bringing out a revolutionary change to Hybrid Routing.

In this paper, routing protocols of wireless Meshnet work is studied about implmentation and verification them on platform. Fistly, routing algorithm of a single-interface Mesh network is studied about implementation routing protocols. This Mesh platform can provid us with wireless aceess, video surveillance and some other services. Experiments results demonstrate that the path throughout will deerease rapidly as the number of Hops increases. Because in a single interface Mesh network, all links are working on the same interfaee, which causes serious interference.

Multicast Routing Algorithm

Multicast is an indispensable communication technique in wireless mesh network (WMN). Many applications in WMN including multicast TV, audio and video conferencing, and multiplayer social gaming use multicast transmission. On the other hand, security in multicast transmissions is crucial, without which the network services are significantly disrupted. Existing secure routing protocols that address different active attacks are still vulnerable due to subtle nature of flaws in protocol design. Moreover, existing secure routing protocols assume that adversarial nodes cannot share an out-of-band communication channel which rules out the possibility of wormhole attack. In this paper, we propose SEMRAW (SEcure Multicast Routing Algorithm for Wireless mesh network) that is resistant against all known active threats including wormhole attack. SEMRAW employs digital signatures to prevent a malicious node from gaining illegitimate access to the message contents. Security of SEMRAW is evaluated using the simulation paradigm approach.

<p>Video Streaming is a method to deliver multimedia content that allow files to be used or watched directly without the need to download and save it. Video streaming also include image processing, in image processing there is a component to compare the value of an image, that is PSNR. This research will compare the reactive and proactive routing protocol performance of AOMDV and DSDV using PSNR, Packetloss, and Throughput parameters in Wireless Mesh Network (WMN) for video streaming. The simulation uses 4, 16, 36, 64, and 100 nodes. The results of this research is AOMDV routing protocol with the greater variation in the number of nodes and the distance between nodes resulting in higher packet loss, decreasing throughput and decreasing values of PSNR. While in DSDV routing protocol with the greater variation in the number of nodes and distance between nodes has an impact on the increase of packetloss value, a very drastic decrease throughput value compared with the AOMDV routing protocol, a decrease in PSNR value and in some scenarios does not produce PSNR values. The comparison of PSNR values between the two routing protocols are also influenced by variations in the number of nodes and distances between nodes along with packetloss and throughput parameters. The greater packetloss will decrease the PSNR value generated.</p>

Since the wireless mesh network topology dynamics and the radio channels instable, the design of wireless mesh network routing protocol become one of the key factors to determine the performance. This paper mainly studied the existing several kinds of typical three-layer mesh network routing protocol (DSDV and AODV), aimed at the defects of three-layer routing limited to the network topology changes, the paper proposed a network model based on two-layer routing. Forwarding the packet, establishing and maintaining the communication links are accomplished on the Mac layer. Simulation tests showed that two-layer routing has a big improvement on the efficiency of packet forwarding, and it effectively reduced the routing overhead and end-to-end delay simultaneously.
