MaNet has emerged as one of the most focused and thrust research areas in the field of wireless networks and mobile computing. In ad hoc mobile networks, routes are mainly multi hop because of the limited radio propagation range and topology changes frequently and unpredictably since each network host moves randomly. Therefore, routing is an integral part of ad hoc communications. Many routing ...

A hybrid switching node structure with light and microwave links is proposed, which is applicable to the future data relay satellite systems, aiming at the development trend of coexistence of lightlink and microwave-link in the future. An experimental system for the light and microwave hybrid switching node based on wavelength selective optical switches (WSS) and optical transceiver modules, is...

In this paper, a new hybrid routing protocol is presented for low power Wireless Sensor Networks (WSNs). The new system uses an integrated piezoelectric energy harvester to increase the network lifetime. Power dissipation is one of the most important factors affecting lifetime of a WSN. An innovative cluster head selection technique using Cuckoo optimization algorithm has been used in the desig...

The influence of explant nodal positions on the in vitro shoot growth and proliferation were studied in the two rose cvs. ‘Bianca’ and ‘El Torro’. Third, fourth and fifth nodal explants were cultured on the modified MS medium supplemented with 1.0 and 5.0 mg/l BA. In both the cultivars, higher rate of proliferation (‘Bianca’ 3.75; ‘El Torro’ 2.65) were obtained from the explants distal to the a...

Mobile Ad hoc Network (MANET) consists of a set of wireless nodes which are connected but can freely move. These mobile nodes include a particular type of nodes, known as ‘gateway’ nodes, which are directly connected with internet and other mobile nodes in a MANET get internet access through them. Prior to access, any mobile node requires discovering such a nearest gateway node using a gateway ...

genetic algorithms, navigation, optimization Real-time navigation requires the dynamic updating of node-node (state) transition costs. These state transition costs are based on, among other things, distance, traffic patterns, and intelligent clustering of nodes based on similarity in the navigator’s intents at each destination, maximum distance preferred between nodes, and other pragmatic consi...

Introduction: All of the Imaging modalities have advantages and disadvantages alone. So if we want to have the best and perfect image, combining these modalities produces something we desired. PET-MR images consist of morphologic and metabolic data. MRI and PET provide high spatial and contrast resolution and high sensitivity and molecular information respectively. Hybrid PET-...

A mathematical model of Calcium Induced Calcium Release in a heart cell has been developed that consists of three coupled non-linear advection-diffusion-reaction equations. A program in C with MPI based on matrixfree Newton-Krylov method gives very good scalability, but still requires large run times for fine meshes. A programming model with CUDA and MPI that utilizes GPUs on a hybrid node can ...
