A trustworthy and energy-aware routing protocol in software-defined wireless mesh networks

Abstract

Abstract-Hybrid Wireless Mesh Networks (HWMNs) were proposed to address the challenges in wireless communications to support mobile applications across different domains. Due to the multi-hop and decentralized network architecture, HWMNs are naturally susceptible to various security threats, especially internal attacks. Therefore, HWMNs must be able to detect anomalies, provide secure routing and protect user privacy through the cooperation among nodes. However, the existing routing protocols for HWMNs cannot ensure the security to protect the users privacy effectively. Moreover, traditional HWMNs are vertically integrated where the control and data planes of mesh routers are bundled together, which makes it complex and difficult to configure the network according to predefined security policies, and to adaptively respond to various dynamic security threats.Software-Defined Wireless Mesh Networks decouple the control plane and data plane of routers and thus enable a more flexible and efficient configuration of security policies. Taking up this opportunity to address the aforementioned challenges, this paper proposes a privacy-aware, secure and energy-aware green routing (PSGR) protocol that can defend against internal attacks, achieve stronger privacy protection and reduce energy consumption in Software-Defined HWMNs. The elaborate theoretical analysis verify that the PSGR protocol can implement the security and privacy protection against internal attacks effectively and efficiently. Simulation results demonstrate a superior performance of PSGR in terms of packet delivery ratio, network throughput and energy efficiency compared to the existing PA-SHWMP, PASER, and HWMP protocols in the presence of Blackhole/Grayhole attacks and wormhole attacks.

Energy-aware wireless mesh network deployment using optimization mechanism

“…Besides, a hybrid (proactive and reactive) routing protocol [12] has also been proposed. Some other mechanisms include software-defined energy-aware routing protocol [13], [14], admission control for preventing fast battery depletion [15], operating certain nodes in sleep mode [16], limiting certain router functions for a period of a time [17], [18], energy aware multi-layer design [19] and topology control mechanism [20], [21]. For channel management, a dynamic channel assignment for wireless mesh network [22] or implementing a genetic algorithm and neural network to optimize energy [23] are also presented.…”

On Platform to Enable the Cognitive Radio Over 5G Networks

“…However, when the global common channel is not available, other neighboring SUs share a separate common available channel. Also, the availability of spectrum is varying continuously, therefore, it is suggested to estimate the availability of spectrum before for efficient transmission [65]. The route selection delivers an important factor in the transmission QoS such as spectrum idle time and spectrum bandwidth.…”

Quality of Service (Qos) Neighbor Routing In Grid and Triangular Mesh Topologies of Wireless Mesh Network

“…The simulation results proved that the PDR values were increased and there was a reduction in the overhead and delay. In 2016, Hui Lin et al [8] proposed a new protocol called PSGR, which is a privacy-aware, secure and energy-aware green routing protocol. This protocol implemented in software-defined HWMNs and it provided security and robust privacy protection and reduces energy consumption.…”
