Review of Routing Protocols and It's Metrics for Wireless Mesh Networks

Abstract.In this paper, we study the impact of multi-radio multichannel Wireless Mesh Networks (WMNs) characteristics on the performance of Expected Transmission Count based metrics (ETX-based). Many characteristics of multi-radio multi-channel WMNs such as channel switching, an absence of a direct connection between neighbors, and difficulty of measuring the packet loss probability in the both forward and reverse direction may affect the performance of ETX-based metrics in hybrid multi-radio multi-channel WMNs compared to static multiradio multi-channel WMNs. Through simulation experiments, we compared the performance of ETX-based metrics with Hop count metric. The experiment result shows the superior improvement of hope count metrics over ETX-based metrics in terms of packet delivery ratio, goodput, and end-to-end delay. From the results, we concluded that major causes of the poor performance of ETX-based metrics in a multi-radio multi-channel WMNs are the extra delay caused by interface switching between channels and the inaccurate value of the ETX-based metrics.

“…The most widely utilized metrics in WMN routing protocols select the shortest path to the gateway based on the hop count, i.e., the number of nodes between the source and the destination. However, prior research has recognized the shortcoming of hop count metrics in WMNs because the shortest path metric results in a congested path [15]. Therefore, many researchers employ quality-aware metrics, which dynamically evaluate link quality characteristics to improve network performance.…”

The introduction of heterogeneous wireless mesh technologies provides an opportunity for higher network capacity, wider coverage, and higher quality of service (QoS). Each wireless device utilizes different standards, data formats, protocols, and access technologies. However, the diversity and complexity of such technologies create challenges for traditional control and management systems. This paper proposes a heterogeneous metropolitan area network architecture that combines an IEEE 802.11 wireless mesh network (WMN) with a long-term evolution (LTE) network. In addition, a new heterogeneous routing protocol and a routing algorithm based on reinforcement learning called cognitive heterogeneous routing are proposed to select the appropriate transmission technology based on parameters from each network. The proposed heterogeneous network overcomes the problems of sending packets over long paths, island nodes, and interference in WMNs and increases the overall capacity of the combined network by utilizing unlicensed frequency bands instead of buying more license frequency bands for LTE. The work is validated through extensive simulations that indicate that the proposed heterogeneous WMN outperforms the LTE and Wi-Fi networks when used individually. The simulation results show that the proposed network achieves an increase of up to 200% in throughput compared with Wi-Fi-only networks or LTE-only networks.

“…According to the characteristics of terminal mobility and the transmission requirements in different networking modes, we have to redesign the networking function for supporting the self-organizing networking ability and dynamic reconfiguration ability. Following this scheme, we implement the corresponding networking protocol in embedded Linux system for running in kernel space, where routing protocols can store and calculate the routing information and maintain the routing Routing protocols are divided into two categories, proactive routing protocols and on-demand routing protocols [15]. In proactive routing protocols, nodes will periodically broadcast announcement frames, perceive the topology changes, and maintain the shortest routing path.…”

Emergency communication and information technology has been an important research field in power emergency disposal industry. The existing onsite power emergency communication is based on satellite communication technology, which is expensive and lack of flexibility. In this paper, we propose to incorporate the technology of broadband wireless self-organizing networks into onsite power emergency communication systems. By analyzing the network architecture that can realize self-healing and high flexibility of onsite coverage, we develop a lightly hybrid networking protocol with the advantages of proactive and on-demand routing. Furthermore, we also design an interactive application software for mobile sharing of multimedia information. Software testing shows that the proposed emergency communication scheme can improve the performance in information submission, command scheduling, and rescue decision-making. Index Terms-Emergency communication, power grid rescue, self-organizing networks, networking protocol, mobile applications Manuscript
