High throughput routing algorithm metric for OLSR routing protocol in Wireless Mesh Networks

Wireless Mesh Networks are new type of multi-hop wireless network with high rate and strong reliability. Multipath routing is employed for load balancing, fault tolerance purposes in wireless mesh networks. With the more and more application need, multipath routing has gradually become an important topic to study. An algorithm of multipath routing algorithm based on dynamic source routing protocol(DSR) is proposed in this paper. This algorithm provides multiple QoS guarantee, such as bandwidth, delay and cost, achieves multipath load balancing and improves networks’ performance. The experimental results show that our algorithm achieves better QoS performance and more advantages over DSR and split multipath routing protocol(SMR).

Considering the high throughput requirement in Wireless Mesh Networks (WMNs), a novel network coding based routing (NCBR) protocol is presented in this paper. The NCBR protocol could actively create potential coding opportunities in the process of path establishment, which attempts to choose an appreciated route with more coding benefits among available path candidates. After this paper gives the proposed coding condition, it describes the working principle of NCBR protocol in detail. Based on NS-2 platform, average end-to-end throughput is measured to evaluate the effectiveness of NCBR by varying the offered load and number of flows. The simulation results demonstrate that the proposed NCBR protocol performs better in enhancing average end-to-end throughput than traditional AODV and AODV+COPE schemes. In particular, average end-to-end throughput could be improved by 11% compared with the AODV+COPE case.

The Wireless Mesh Networks (WMNs) technology has recently emerged as a promising high-speed wireless technology, which provides the last mile broadband Internet access and delivers integrated wireless communication solutions. Integrating the traditional wireless with new wireless technologies such as cognitive radio (CR) technology creates a platform for high-speed broadband communication. In a multihop ad hoc cognitive radio network (CRN) environment, the performance of the network is degraded by the routing protocols, which are adapted from the traditional wireless networks. In an endeavor to optimize the performance of the CRNs, existing routing protocols can be adapted and optimized. Secondly, new dynamic routing protocols can be designed to meet the requirements of CRNs. This paper investigates the existing routing protocols in WMNs and proposes a new routing protocol called extended Weighted Cumulative Expected Transmission Time (xWCETT). The xWCETT routing protocol was evaluated through network simulations using the NS 2. Its performance was evaluated with respect to the end-to-end average latency, the throughput, jitter, packet delivery ratio, and the normalized routing load. The comparative evaluation results show that the xWCETT achieves superior results in terms of average throughput, latency, and the normalized routing load.
