Item Multicasting in wireless mesh networks: Challenges and opportunities(2009) Kumar, K.K.S.; Hegde, S.Wireless Mesh Network (WMN) is a multi-hop wireless network with partial mesh topology, which can replace wired infrastructure backbone in a traditional wireless network, to wireless. It is an exciting new technology that has applications in defense, metro-area Internet access, and disaster management. WMNs are believed to be a highly promising technology and will play an increasingly important role in future generation wireless mobile networks. This paper presents a survey on multicast protocols in wireless mesh networks and factors to be addressed while designing a multicast protocol for wireless mesh networks, like availability of mesh router infrastructure, effect of multiple channels and channel assignment, load balancing, selection of multicast routing metric, effect of guaranteed Quality of Service, andcross layer optimization. © 2009 IEEE.Item Congestion adaptive routing in wireless mesh networks(2010) Tiwari, A.K.; Basavaraju, T.G.; Chandavarkar, B.R.The main reason for packet loss in Wireless Mesh Networks (WMNs) is due to congestion. Presently, routing in WMNs is not congestion-adaptive. Routing may let a congestion happen which is detected by congestion control. The way in which the congestion is handled results in longer delay and more packet loss and requires significant overhead if a new route is needed. Hence, we propose a congestion adaptive routing protocol (CARP) for WMNs with such properties. Our ns-2 simulation results confirm that CARP can successfully achieve a high packet delivery ratio with lower routing overhead and latency in WMNs. ©2010 IEEE.Item Cross-layer IDS for rushing attack in wireless mesh networks(2012) Karri, K.; Santhi Thilagam, P.; Rao, B.N.Wireless Mesh Networks (WMNs) are a promising technology to provide the wireless internet connectivity. WMNs are becoming a popular choice for wireless internet service providers to offer internet connectivity as it allows a fast, easy and inexpensive network deployment. However, security in WMNs is still in its infancy. Security and privacy has been a major concern in WMNs. WMNs are susceptible to broad variety of attacks due to its open medium, dynamic topology and lack of physical security. WMNs are more vulnerable in Network layer. Several attacks are possible in the network layer. Some of the attacks have possible solutions but there is no solution for to detect Rushing attack which leads to the Denial of Service. In this paper, the authors proposed Cross- Layer Intrusion Detection System (CLIDS) for Rushing attack. We evaluated the performance of our technique using network simulator 2. Simulation results show that CLIDS has less false positive and false negative rates than single layer intrusion detection system. Copyright © 2012 ACM.Item Enhanced Clustering and Channel Allocation in Wireless Mesh Networks(Springer Science and Business Media Deutschland GmbH, 2025) Sushma Reddy, C.V.; Harshini, V.; Rayala, A.; Chandavarkar, B.R.Wireless mesh networks (WMNs) are crucial for establishing adaptable and scalable communication infrastructures among interconnected devices. Effective clustering and channel allocation are vital for enhancing WMN performance by addressing energy efficiency, latency, throughput, and interference challenges. Proper clustering facilitates the organization of network nodes into cohesive groups, enhancing communication efficiency and resource utilization. Additionally, channel allocation strategies ensure minimized collisions and improved overall network throughput, enhancing network stability and reliability. Existing approaches, such as clique-based channel assignment (CCCA) and two-hop neighbor clustering, present complexity, and interference level limitations. The significant contribution of this paper is to introduce a novel approach focused on clustering and channel assignment, referred to as enhanced clustering and channel allocation (ECCA), to optimize WMN performance—the clustering technique groups nodes based on maximal cliques in one-hop neighbors. Furthermore, channel assignment strategies are employed to minimize collisions and improve overall network throughput. The performance of ECCA is compared with state-of-the-art clique-based channel assignment (CCCA) in terms of the modularity, average number of nodes per cluster, average node degree, and coefficient of variance. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
