“…For the first part of the formula, every link in a path should compute a value of CBT, and the computing time of CBT in a whole path is n-1. For the second part, the regional energy-consumed condition is computed as equation (4) at every node in a path. The computation complexity of this process depends on formula (3).…”

“…Hybrid WMN combines advantages of infrastructure WMN and client WMN, which has stronger network connectivity, higher reliability, and larger coverage. 4,5 Its structure is quite more flexible and closer to actual demand than infrastructure WMN or client WMN. 6 In hybrid WMN, mesh routers have high capacity and stability, while mesh clients have limited energy and high mobility.…”

Existing routing protocols for hybrid wireless mesh network neglect the negative impact on network lifetime and route stability caused by energy constraints and mobility of mesh clients. To solve this issue, a regional energy-and mobility-aware routing protocol is proposed in this article. Both energy and mobility features in hybrid wireless mesh network are considered in this routing protocol. On one hand, within the communication transmission range, the intensity and degree of dispersion in energy consumption can be perceived. The node whose neighbor area has sufficient energy can be selected for network services, which can balance energy and extend the network lifetime. On the other hand, the mobility of clients is considered to enhance the stability and reduce network overhead. Therefore, regional energy-and mobility-aware routing protocol can balance network energy consumption, prolong network lifetime, and improve route stability. Simulation results via NS2 show that regional energy-and mobility-aware routing protocol can achieve better performance significantly.

“…Hybrid WMNs consist of relatively static mesh routers which form the backbone of the network and mobile clients. Mobile clients can act as a dynamic extension of the backbone network by implementing routing functionality, and improve the connectivity and coverage inside the WMNs [2], [3]. In this paper, we mainly focus our research on hybrid WMNs.…”

Route selection in hybrid wireless mesh networks (WMNs) that contain mobile mesh clients with constrained energy is a critical research challenge. Existing routing protocols take the advantages of backbone mesh routing protocols but lack of consideration of the characteristics of clients. Most of these protocols capture interference and traffic load, but lack of considering the effect of mobility and energy constraints of clients. In this paper, we propose a Cross-Layer Aware (CLA) routing protocol, which is based on comprehensively considering characteristics of mesh routers and mesh clients for gateway traffic in hybrid WMNs. In CLA, we propose a new routing metric jointly considering four parameters in a cross-layer design: the MAC layer channel condition, the routing layer path length, the application layer mobility and constrained energy of clients. These parameters can capture the interference, traffic load, stability and energy efficiency, so as to select an optimum route. In addition, we develop a constrained forwarding mechanism to reduce flooding overhead by limiting the forwarding number of clients in CLA, which can reduce the energy consumption wasted in overhead. Simulation results show that the proposed CLA protocol can effectively improve the whole network performance.

“… Black Mailing Attacks: A malicious node can black mail another node by propagating false information that the other node is malicious, which can disrupt the network's normal operation and consume network's precious resources [22].  Replay Attacks: a malicious node can resend old packets as if they are new ones they could be very destructive if these packets are old routing information, which will make all nodes are unreachable [23].  Selective Misbehavior Attacks: a misbehaving node can select when and to whom it misbehaves [21].…”

Mobile Ad hoc Networks (MANETs) consist of self-governed nodes, they have no fixed infrastructure. They are stand alone or connected to the bigger internet as per the different applications. The dynamic nature of MANETs adds many challenges to the network management techniques. Likewise, their special characteristics such as the lack of infrastructure, self-government, mobility, and limited resources makes them vulnerable to a lot of attacks. Reputation systems can help mitigating attacks. Trust management using a reputation mechanism is considered as a vibrant security solution to enable the collaboration of MANETs. In this paper, we propose a Functional REPutation system for Ad hoc Networks, (FREPAN), which aims to improve the MANETS performance and mitigate selfishness and misbehavior attacks' effects. The overall system structure is introduced and its performance is tested under the presence of the jellyfish attacks.
