Nelder-Mead Based Iterative Algorithm for Optimal Antenna Beam Patterns in Ad Hoc Networks
Directional antennas shape transmission patterns to provide greater coverage distance and reduced coverage angle. Use of adaptive directional antenna arrays can minimize interference while also being more energy efficient. When used in an ad-hoc network, this reduces interference among transmitting nodes and thereby increases throughput. Such “smart antennas” use digital beamforming based on si...
متن کاملA New Routing Algorithm for Vehicular Ad-hoc Networks based on Glowworm Swarm Optimization Algorithm
Vehicular ad hoc networks (VANETs) are a particular type of Mobile ad hoc networks (MANET) in which the vehicles are considered as nodes. Due to rapid topology changing and frequent disconnection makes it difficult to design an efficient routing protocol for routing data among vehicles. In this paper, a new routing protocol based on glowworm swarm optimization algorithm is provided. Using the g...
متن کاملAn Iterative Quality-based Localization Algorithm for Ad Hoc Networks
In this paper an iterative quality-based algorithm for location discovery is presented which can be used in wireless ad hoc sensor networks. The algorithm will take the reliability of measurements into account and will produce a reliability index for every estimated location using a statistical approach. The algorithm can also work in a hybrid network with different kinds of distance measuring ...
متن کاملGrid Restrained Nelder-Mead Algorithm
Probably the most popular algorithm for unconstrained minimization for problems of moderate dimension is the Nelder-Mead algorithm published in 1965. Despite its age only limited convergence results exist. Several counterexamples can be found in the literature for which the algorithm performs badly or even fails. A convergent variant derived from the original Nelder-Mead algorithm is presented....
متن کاملMulti-beam Antenna-based Topology Control Algorithm in Ad Hoc Networks
Multi-beam antenna is drawing attention due to its power-saving and interference-reducing. A topology control algorithm K-DRNG based on multi-beam antenna in heterogeneous wireless Ad Hoc network is proposed. The algorithm is mainly composed of three phases. In the stage of information collection, each node collects information of neighborhood by adjusting the transmitting power and controlling...
