TL;DR: It can be shown that R-AODV does provide a more reliable data transfer compared to the normal AODV if there are malicious nodes in the MANET, and enhances security by ensuring that data does not go through malicious nodes that have been known to misbehave.
Abstract: A mobile ad-hoc network (MANET) is a peer-to-peer wireless network where nodes can communicate with each other without the use of infrastructure such as access points or base stations. Nodes can join and leave the network at anytime and are free to move randomly and organize themselves arbitrarily. Due to this nature of MANET, it is possible that there could be some malicious and selfish nodes that try compromise the routing protocol functionality and makes MANET vulnerable to security attacks. In this paper, we present a security-enhanced AODV (Ad hoc On-demand Distance Vector Routing) routing protocol called R-AODV (Reliant Ad hoc On-demand Distance Vector Routing). The implementation of this work is done by modified a trust mechanism known as direct and recommendations trust model and then incorporating it inside AODV which will allow AODV to not just find the shortest path, but instead to find a short path that can be trusted. This enhances security by ensuring that data does not go through malicious nodes that have been known to misbehave. The R-AODV protocol has been implemented and simulated on NS-2. Based on the simulation result, it can be shown that R-AODV does provide a more reliable data transfer compared to the normal AODV if there are malicious nodes in the MANET.

TL;DR: In this article, the routing information of neighboring mesh APs is monitored via a dedicated monitoring antenna of a current mesh access point (AP) in a multi-radio wireless mesh network.
Abstract: Techniques for providing multi-radio wireless mesh network solutions are described herein. According to one embodiment, routing information of neighboring mesh APs is monitored via a dedicated monitoring antenna of a current mesh access point (AP). The current mesh AP is one of mesh APs of a wireless mesh network, each having an uplink antenna, a downlink antenna, a local link antenna, and a monitoring antenna. Traffic of an uplink antenna of the wireless mesh AP is dynamically reconfigured and rerouted from a first routing path coupled to a first uplink mesh AP to a second routing path coupled to a second uplink mesh AP, if the second routing path has a better routing condition than the first routing path based on the monitored routing information associated with the first uplink mesh AP and the second uplink mesh AP. Other methods and apparatuses are also described.

TL;DR: A new RPL-based routing protocol, termed as directional mutation ant colony optimization-based cognitive RPL (DMACO-RPL), for CR-enabled AMI networks, which utilizes a global optimization algorithm to select the best route from the whole network.
Abstract: Advanced metering infrastructure (AMI) networks, which are an integral component of the smart grid ecosystem, are practically deployed as a static multihop wireless mesh network. Recently, routing solutions for AMI networks have attracted a lot of attention in the literature. On the other hand, it is expected that the use of cognitive radio (CR) technology for AMI networks will be indispensable in near future. This paper investigates a global optimization-based routing protocol for enhancing quality of service in CR-enabled AMI networks. In accordance with practical requirements of smart grid applications, we propose a new RPL-based routing protocol, termed as directional mutation ant colony optimization-based cognitive RPL (DMACO-RPL), for CR-enabled AMI networks. This protocol utilizes a global optimization algorithm to select the best route from the whole network. In addition, DMACO-RPL explicitly protects primary (licensed) users while meeting the utility requirements of the secondary network. System-level simulations demonstrate that the proposed protocol enhances the performance of existing RPL-based routing protocols for CR-enabled AMI networks.

TL;DR: A new distance-based clustering routing protocol, LEACH-SC (LEACH-selective cluster), which can greatly reduce the overall network energy consumption, balance the energy consumption among the sensors and extend the lifetime of the network.
Abstract: Cluster-based routing protocol is always a hot research area in wireless sensor networks. Classical LEACH protocol has many advantages in energy efficiency, data aggregation and so on, so it is widely used until now. In this paper, based on the LEACH protocol, we propose a new distance-based clustering routing protocol, LEACH-SC (LEACH-selective cluster).In LEACH-SC, a new method is used to choose cluster heads, i.e. an ordinary node A will choose a clusterhead which is the closest to the center point between A and the sink. The simulation results show that compared with LEACH, LEACH-SC protocol can greatly reduce the overall network energy consumption, balance the energy consumption among the sensors and extend the lifetime of the network.

TL;DR: A new hybrid wireless routing protocol specifically designed to address scalability, which combines features of reactive routing with location-based geographic routing, in such a manner so as to efficiently use all the location information available.
Abstract: A key design issue in routing for wireless ad hoc networks is scalability. By scalability we mean the ability of the network to support increases in node numbers without significantly degrading network performance. In this work we introduce a new hybrid wireless routing protocol specifically designed to address this issue. Our new protocol combines features of reactive routing with location-based geographic routing, in such a manner so as to efficiently use all the location information available. The protocol is designed to gracefully exit to reactive routing as the location information degrades. Another aspect of our protocol is that it can be spatially dependent - meaning different physical areas of the network can be using quite different routing procedures at the same epoch. That our protocol can dramatically increase scalability can be measured via the routing control overhead which we show, through analysis and simulation, to be significantly reduced relative to current protocols. This is particularly so when a large fraction of nodes possess up-todate accurate location information. Our new protocol operates even though nodes can be mobile, and it provides an enhanced, yet pragmatic, location-enabled solution that can be deployed in all emerging wireless ad hoc networks.
