“…In this problem domain, authors in [24] proposed a technique called Congestion Avoidance Hybrid Wireless Mesh Protocol (CA-HWMP), which gives preference to avoids the congestion before its occurrence to improve packet delivery and improve network throughput. In this paper, we included the details about the proposed idea, algorithm and its limitations in Section III.…”

“…In WMN, routing is performed at the Data Link layer, and the proposed mechanism utilizes this routing protocol for congestion avoidance with small modification in basic mechanism. That is why it is named as Congestion Avoidance Hybrid Wireless Mesh protocol (CA-HWMP) [24] and it uses HWMP in IEEE 802.11s with modification in mechanism for congestion avoidance. It includes three steps, monitoring, notification and intelligent re-routing.…”

“…In literature, researcher proposed a number of congestion control mechanisms to resolve this problem, but every protocol has own limitations. In [24], we proposed a routing protocol to avoid congestion mechanism to address this problem which increase the throughput of the network. In this paper, we evaluate the proposed technique for congested scenarios and found that this protocol helps to reduce delay and packet loss.…”

Abstract-The wireless technology is one of the core components of mobile applications with mobility support at low deployment costs. Among these, Wireless Mesh Network (WMN) is one of the technologies that supports mobile users for un-disrupted, reliable data connectivity, provides high bandwidth even in areas, where access of such services is difficult. Additionally, it features capabilities like self-configuring, self-healing, and self-organizing. IEEE proposed a MAC standard for WMN enhancements named IEEE 802.11s for multi-hop networks. Within this standard, the mandatory routing protocol called Hybrid Wireless Mesh Protocol (HWMP) is proposed for efficient utilization of resources to achieve high bandwidth at MAC layer. To improve this protocol, a congestion avoiding protocol was proposed, which utilizes alternate paths just before the congestion state is reached. The proposed technique does not add any overhead, it utilizes congestion notification frame, which is already part of standard. This paper discusses simulation results of the proposed routing protocol against the existing HWMP protocol for packet delivery fraction, throughput and delay. The results indicate that the proposed technique significantly improves performance of IEEE 802.11s.
